The Pentax Papers, Part 3, from the Super A of 1983 to the *ist of 2003

The last Pentax 35mm SLRs: great shooters that are often overlooked.

By Jason Schneider

In a way, all the analog Pentax SLRs that came after the glorious pro—level Pentax LX released in 1980 live in its shadow, and none surpassed it in terms of overall performance, construction and elegant design. However, the succeeding Pentax A-series, three models that debuted in 1983 and were in production for 4-5 years, all included noteworthy technical advances. They added a programmed autoexposure (P) mode to what were basically M-series bodies, and that required a new KA mount that allowed in-body control of the lens aperture. The KA mount was backward compatible, allowing K-mount lenses to be used in manual and aperture-priority mode on KA-mount cameras. And the Pentax A series were the first Pentax cameras to use in-finder LCD digital displays for exposure information. The Pentax super A/ super PROGRAM and the program A/program PLUS also had a translucent window of the front of the pentaprism housing to illuminate the LCD without requiring battery power.

Pentax Super A (Super Program in N. America)

Introduced in 1983, the Pentax Super A/Super Program was accompanied by a new line of SMC Pentax-A in KA mount with an "A" lock on the aperture ring that allowed the body to set the f/stop for programmed and shutter priority AE modes. The camera can also be used in aperture priority AE and metered manual exposure and has two flash modes (TTL auto flash and a programmed mode for dedicated flash units). Lenses with earlier versions of the K-mount (K and KF) can also be used, but without shutter-priority or programmed AE modes.

Exposure modes are selected using a dial concentric with the shutter release, along with the aperture setting of the lens. The shutter dial has the following positions:
L (locked)
AUTO
M (manual shutter-speed selection)
125 (shutter speed fixed at 1/125 sec for flash sync)
B ('B' shutter setting)

In the Auto position, setting the aperture to 'A' on the lens gives programmed AE; any other aperture value gives aperture-priority AE. In the 'M' position on the dial, setting the aperture to 'A' gives shutter-priority AE; any other value gives metered manual exposure. Shutter-priority AE works normally if the shutter speed is set to 1/125 sec.

The Super A offers a wide shutter speed range of 15 to 1/2000 sec. Shutter speeds are selected electronically via rocker buttons on the top panel, a method used the Pentax ME Super. The selected speed is displayed in an LCD panel next to the release, and simultaneously in the viewfinder. Another LCD in the viewfinder shows the aperture value when in programmed or shutter-priority AE, but not in aperture-priority AE. In metered manual mode, the second viewfinder LCD shows the number of stops over- or under-exposure in up to +/-3EV values based on center-weighted average readings.

The camera is compatible with Pentax dedicated flashes, and there’s an in-finder flash-charging indicator. With dedicated flashes that support TTL metering, the camera automatically sets the proper lens aperture, when in programmed or shutter-priority AE, and the flash indicator in the viewfinder flickers after exposure, to verify correct exposure.

The viewfinder has a central split-prism rangefinder surrounded by a microprism collar, and the camera accepts an external winder (once finger-grip on the front of the body is removed). There’s a self-timer to the right of the lens mount and a PC contact on the left. The camera requires two 1.5V LR44 alkaline or SR44 silver-oxide batteries, or an equivalent 3V lithium battery. The viewfinder LCDs alternate correct settings data and an 'ooo' readout when the batteries are low.

Note: The Super A was followed in 1984 to 1988 by the similar Pentax Program A/Program Plus— a less expensive model, that lacks the Super A's top LCD and 1/2000 sec shutter speed and offers programmed AE but not shutter priority AE.

While neither the Pentax Super A/super Program or the Pentax Program A/Program Plus has the visceral panache of a Pentax LX or even an MX, these models are clearly among the best buys out there for anyone hankering to get into analog photography on the cheap. They’re widely available complete with 50mm f/1.4 Pentax lens for $150 to $200 and you may be able to glom onto a nice one for even less. In terms if picture talking potential per dollar that’s awesome.

Pentax A3 (A 3000 in the Americas). The A 3000 was introduced in 1984 and ceased production in 1987. It uses the Pentax KA bayonet mount, features programmed autoexposure (P mode), has a built-in winder, an electronically controlled Seiko vertical metal focal plane shutter with speeds of 2 sec to 1/1000 sec, flash sync at 1/60 sec, and a 12-sec self-timer. Its TTL center-weighted open aperture metering system covers a range of EV 1 to 18 (at ISO 100 with f/1.4 lens) and provides DX coding (plus manual settings) for films ISO 25 to 1600. Conceived as a broad- spectrum entry level model, the Pentax A 3000, which is powered by 2 AA batteries, is a fine choice as a walkaround analog SLR, and you can snag a clean used one with lens for only $50 to $75 or even less!

The Pentax P Series

No, the P denoting the Pentax P-series doesn’t stand for “plastic” even though all these cameras have plastic outer body parts over a cast alloy chassis. The P really stands for P (programmed autoexposure) mode, a common feature of all 4 models. Other common features include manual mode, DX-code auto film speed setting (which defaults to ISO 100 if the code can’t be read), an exposure lock, and a depth of field preview. All but the P3/P30 also offer Av (aperture priority) mode, and the P5/P50 has +/- 3EV exposure compensation. Note: What P-series Pentaxes may lack in terms of “pride of ownership” they’re outstanding when it comes to picture taking performance per dollar.

Pentax P30/P3 1985-1988: Known as the P3 in the U.S. and the P30 elsewhere, it was a broad-spectrum camera aimed at casual shooters as well as enthusiasts and it featured traditional shutter speed dial with a PROGRAM AE setting, It features a KA mount for P mode, provides Av mode when M or K series lenses are used, and works with any manual focus lens up to the FA series.

The pentaprism viewfinder covers 92% of the on-film image at 0.82x magnification and has a matte focusing screen with a horizontal split-image rangefinder. Its manual wind lever has a 130° throw, modes include Program, Manual X and B exposure modes, and it provides shutter speeds of 1 to 1/1000 sec (down to 8 sec in P mode), The X mode provides automation with some Pentax flashes, and there’s an exposure lock, but no exposure compensation. The meter provides center-weighted readings from EV1 to EV 18 (at ISO 100 with f/1.4 lens) and in-finder LEDs show the selected and recommended (blinking) speeds. DX coding ranges from ISO 25-1600, but there’s no manual film speed setting. Other features: 12-sec self-timer, DOF preview lever, power supplied by two 1.5v SR44 or LR44 button batteries. The U.S. P3 version is all black; international P30 versions are dark gray.

Pentax P50/P5 1986-1989: Dubbed the P5 in the U.S, this manual focus KA mount camera has2 Program modes, a large LCD on top, and a total of 5 exposure modes. Settings are displayed on an LCD to the right pf the pentaprism housing and selected by navigating the menu with “up” and “down” buttons adjacent to the display. Major modes include Programmed AE biased toward fast shutter speeds, Programmed AE biased toward small apertures, Aperture Priority AE, Metered manual exposure, and P mode for dedicated flash. Shutter is a vertical travel metal focal plane with speeds of 1 to 1/1000 sec plus B, and flash sync is at 1/100 sec. The camera is compatible with some dedicated Pentax flash units, reads DX film speed codes, but has no manual ISO settings. It’s powered by two 1.5v LR44 alkaline or SR44 silver-oxide batteries.

Pentax P30n/P3n (1988-1990) and P30t (1990-1997): The Pentax P30n (P3n in the U.S.) is an improved iteration of the Pentax P30/P3 that provides aperture-priority and fully programmed autoexposure as well as metered manual exposure. It uses a KA bayonet mount to convey aperture information, enabling P and AV modes, and metered manual exposure, and is compatible with any manual focus lens up to the FA series. All other features closely parallel those of the Pentax P30/P3.

The Pentax P30t of 1990 has a diagonally split rangefinder focusing screen, and a plastic film door inn place of the metal film door used on previous models. It sold well and remained in production for 7 years.

Note: All P-series Pentax models are readily available on the leading online auction sites, typically at around $50-75 in clean working condition with 50mm f/2 or 50mm f/1.7 Pentax lens. They’ll probably never be prized as collector’s items but they’re awesome picture takers.

The Pentax SF Series (1987-1993)

The Pentax SFX (SF1 in the U.S.) was the world’s first AF SLR with a built-in retractable TTL auto flash (Pentax called it the “RTF,” an acronym for Retractable TTL Flash). The SF series also incorporated the advanced Pentax SAFOX (Sensor Ability Fortifying Optical Correction System) autofocus module, which performed on a par with those of Pentax’s archrivals, Nikon, Canon, and Minolta.

Pentax SF-1 with Pentax 35-70mm f/4 Zoom Lens. This popular Pentax of 1987 offered multiple exposure modes and unique shutter specs.

The Pentax SFX (SF1) of 1987 to 1989 was an enthusiast aimed model that provides Programmed, Aperture Priority, and Shutter Priority AE plus metered manual mode, has a metering range of EV 1 to EV 20 at ISO 100 with 50mm f/1.4 lens, and offers exposure compensation of +/- 4 stops in half stop increments. Shutter speeds range from up to 7 hours (!) to 1/2000 sec plus B, with flash sync at 1/100 sec, and its K-AF mount also accepts all K-mount manual lenses and M42 mount lenses with an adapter. Focusing modes include AF Single, AF Servo, and manual, and lenses autofocus in about 0.3 sec with or without the AF Spotbeam aid that gets out to 4m. The dioptric adjustable pentaprism viewfinder provides a 92% field of view, has LED readouts for focus confirmation, exposure, shutter speed and flash readiness. The built-in pop-up flash has a metric guide number of 14 at ISO 100. Other features: Top-mounted full-info LCD, self-timer, auto wind (to 1.8 fps) and auto rewind The Pentax SFX (SF1) is powered be one 2CR5 lithium battery or 2 AA cells in the optional grip. Standard lens was the SMC Pentax 35-70mm f/3.5-f5.6 Pentax Zoom with macro feature, and the camera weighs in at 665g without battery.

Pentax SFXn/SF1n 1989-1993: The successor to the Pentax SFX (SF1) that was in production for 4 years, it employs a vertical metal focal plane shutter with speeds from 30 to 1/4000 sec (note: speeds slower than 1/30 sec are available only in manual mode), and provides flash sync at 1/125 sec. Exposure modes include Programmed AE (that can be set to normal, action, and depth sub-modes), Aperture Priority, Shutter Priority or metered manual. It can be set for DX-coded films (ISO 25-5000) or manual settings from ISO 6-6400 in 1/3-stop intervals. It provides motorized film transport at up to 2.2 fps and is powered by one 2CR5 lithium battery or four AA batteries with the optional grip. Other features, including the retractable built-in flash, closely parallel those of the SF1.

Both the Pentax SFX (SF1) and the Pentax SFXn/SF1n are functionally excellent user cameras for serious analog shooters and more versatile than most thanks to their multiple exposure modes, built-in flash, and reasonably good AF performance even by modern standards. The fact that you can snag a clean working example complete with original Pentax lens for a paltry $50 to $75 makes them excellent choices as primary or backup cameras. While their “post-modern retro” styling may not be everyone’s cup of tea, ergonomically they’re quite good.

Pentax SF7 (SF10 in some territories) 1988 -1993. This autofocus 35mm SLR was designed to provide a range of exposure modes with Pentax ‘F’ series KAF lenses. Programmed, or Shutter Priority AE modes require camera control of the lens aperture and are only available if an ‘F’ lens is mounted; earlier lenses can be used for other modes but will not support all functions. However, AF can be used with any K-mount lens mounted on the AF Adapter 1.7X, provided it has an aperture of f/2.8 or wider.

Pentax SF-7 with Pentax 35-70mm f/3.5-4.5 zoom: With built-in flash and flexible exposure options it's now a great choice at a bargain price.

Settings displayed on a large LCD panel at the rear of the pentaprism housing are selected using a mode button and a knurled selector switch next to the shutter release. The camera has a vertical travel metal focal plane shutter with speeds from 30 to 1/2000 sec (1-1/2000 sec plus B in manual) with flash sync at 1/100 sec. The camera supports programmed auto flash or TTL metered flash with select Pentax flash units and has a small folding built-in flash (metric GN 12 at ISO 100), and there’s a flash ready indicator in the finder. Other features: hot shoe, DX setting for films ISO 25-5000, default setting of ISO 100, but no manual ISO settings. Auto focus is switchable via an AF/MF switch on the side of the lens mount. At used prices ranging from about $35 to $85 with Pentax prime or zoom lens, the SF7 qualifies as a bargain.

Pentax Z/PZ series, 1991-1995

The second generation of Pentax autofocus 35mm SLRs, they incorporate the upgraded SAFOX II AF module and power contact to enable the power zoom function with Pentax FA zoom lenses. All U.S. models were called “Z” and international models designated “PZ.”

The flagship Pentax Z-1 of 1991 utilizes KAF2 lenses and is also compatible with earlier K-mount lenses. KAF lenses support most Z-1 features except those related to power zoom capability. KA lenses with apertures of f/2.8 or faster can be used, but only with the AF Adapter 1.7X; without the adapter lenses with apertures of f/5.6 or faster can be focused using the Focus Indicator (FI), and in Shutter Priority and Programmed AE modes. Manual aperture K-mount lenses can only be used in Aperture Priority AE and manual modes. A special edition Z-1 SE was issued in 1994 to commemorate the 75th Anniversary of Asahi Optical company, and the Z-1 was succeeded by the Z-1p in 1995.

These versatile, high-performance cameras are excellent choices for serious analog shooters. If you decide to take the plunge, make sure the one you buy comes with no questions asked full refund return privileges—they’re generally reliable, but expensive to repair if problems arise.

Pentax PZ-20/Z-20 in the U.S. 1992

The Pentax Z-20 is a broad-spectrum, mid-level autofocus 35mm SLR with a built-in retractable TTL auto flash that uses Pentax KAF2 -mount lenses and provides power zoom capabilities. It uses an electronically controlled vertical-run metal focal plane shutter with speeds from 30-1/2000 sec and has a 12-sec electronic self-timer. Exposure modes include picture modes (portrait, landscape, action, and closeup) Program, AV, Tv, and metered manual mode. The metering system covers a range of EV 1 to EV21 (at ISO 100 with 50mm f/1.4 lens, the ISO 35-5000 DX coding system is complemented with manual ISO settings of 6 to 6400, exposure compensation of +/- 3 stops is adjustable in ½ steps, the built in pop-up flash has a metric Guide Number of 13, the built in motor advances the film at up t 2 fps, and it’s powered by a 2CR5 lithium battery.

Pentax Z-20 body.jpg
Pentax Z-20 body incorporated a TTL phase-matching SAFOX II AF system for enhanced AF performance, and 6-segment multi-metering.

The Pentax Z-20 employs a TTL phase-matching SAFOX II AF system, provides a focus lock, and enables 3-speed power zoom, Zoom Clip Mode, Image Size Tracking Mode, and Auto Zoom Effect when used with an FA zoom lens. The Penta-mirror finder uses an Aspheric Micro Matte focusing screen, covers a 92% field of view at 0.77x magnification, and provides lighted full-info readouts in the finder and via a full-info LCD panel. Other features: auto loading and auto rewind, TTL 6-segment multi-metering, a learning function in Hyper Program Shift, and a removable back cover. It measures 5.7 x 3.7 x 2.5 inches (W x H x D) and weighs in at 17.6 ounces, body only without battery.



The Z-20 is an excellent all-around shooter, except perhaps in low light where its slightly dimmer penta-mirror viewfinder isn’t the hot ticket. The Pentax Z-20 is readily available used in clean working condition with Pentax prime or zoom lens at prices in the $50-125 range. You can occasionally snag one fir a lot less and truly mint examples may be somewhat higher priced.

Pentax PZ-70 (Z-70 in the U.S.) 1995

Pentax Z-70 with SMC Pentax 35-80mm 1/4-5.6 lens. A creditable camera compromised by its plastic lens mount. What were they thinking?

With a feature set closely paralleling that of the Z-20, the Pentax Z-70 is a versatile, feature-packed camera that offers a lot of flexibility and control to photographers at a modest price and is an excellent value.​

One deficit: it has a plastic lens mount instead of a metal one, so if you’re a heavy user or change lenses often, you might prefer a different Pentax model. The good news: The Pentax K-70 is dirt cheap, about $35-60 in nice shape with Pentax zoom or prime lens.

Pentax MZ/ZX Series

The innovative MZ/MX series brought back the concept of small and light back to the AF SLR forefront from the previous generation of manual focus Pentaxes. Known as MZ Series internationally they were, except for the MZ-S, known as ZX models in the U.S. The exception to this rule is the MZ-6, which was dubbed the ZX-L in the U.S. All members of this series are compact autofocus SLRs except for the manual focus MZ-M. The flagship model MZ-S features an all metal body, a faster framing motor, and a higher flash sync speed. Only the MZ-S and MZ-6 are compatible with the new P-TTL flash system—both models can control flash wirelessly using the popup flash in commander mode at both normal and high-speed sync settings. Note: more advanced SAFOX IV/V autofocus modules are integrated into this series.

Pentax MZ-S (Flagship model)

The Pentax MZ-S was introduced in 2001 as the top-of-the-line Pentax SLR with a study body of magnesium alloy. It reintroduced analog dials and had a slanted top panel as a distinguishing feature. It has high speed flash synchronization at 1/180 sec and shutter speeds up to 1/6000 sec. The flash system works with the in-camera flash as well as with the AF360FGZ wireless TTL flash unit. The MZ-S also featured imprint of exposure information on the edge of the film.

Pentax MZ-S with Pentax SMC 35-80mm f4-5.6 zoom: This formidable full-featured model commands premium prices on the used market.

Program modes: Normal, Action, Depth of field and MTF (Modulation Transfer Function). In the MTF program the camera sets the aperture to the value where the lens performs the best under the given light (it only works with F and newer lenses which has the required information encoded in them). Pretty spiffy.

Here's one reviewer’s assessment of the virtues of the Pentax MZ-S:

The MZ-S gives you boatloads of capability if you want to tap into it. It has 19 programmable functions ranging from setting auto bracketing to using the internal flash as a trigger for an external flash.

Here’s my assessment of the key selling features of this camera:
  • Autofocus, using a six-point version of Pentax’s SAFOX AF technology.
  • Six-point metering with options for center-weighted, spot or multi-segment.
  • 1/180 flash sync.
  • 1/6000 maximum shutter speed (I’ve never needed it, but it seems cool to have).
  • DX coding with manual override.
  • Automated film advance/rewind at up to 2.5 frames per second (blisteringly fast for 2001, I suppose).
  • Depth of field preview.
  • Bright viewfinder with 92% view (you can even have the focusing screens changed out if you want).
  • Photo information data imprinting (outside the image area… you’ll likely need a loupe to read it though).
  • Film reminder window for the forgetful.
  • And of course, the venerable K mount with its access to a universe of lenses.
Highly valued and much appreciated by Pentaxians, the Pentax MZ-S commands a premium price on the used camera market. They’re readily available but they typically run about $300 to $350 in good nick at the leading online auction sites and perhaps even more for mint examples fitted with a desirable lens like the superb Pentax 28-70mm f/4 Zoom. This could well be a case of getting what you pay for.

Pentax MZ-5 (ZX-5 in the U.S.)

Introduced in 1996 this enthusiast aimed autofocus 35mm SLR uses the Pentax KAF2 mount, which accommodates earlier K-mount lenses, and sports a traditional shutter speed dial. Its electronically controlled vertical metal-bladed shutter provides speeds of 30 to 1/2000 sec, its exposure system incorporates Av, M, P, and TV modes except that P and Tv modes are not available with M and pre-A type lenses lacking an “A” setting on the aperture ring. A, F, and FA lenses support 6-segment evaluative, center-weighted, and spot metering modes while K and M series lenses support center-weighted and spot. Other features: +/- 3EV exposure compensation in ½ EV steps, metal lens and tripod mounts.

This camera and its later variants (e.g. the ZX-5N QD) are currently listed at silly prices ($25 to $50) with or without lens on the leading online auction sites. They’re great shooters for the money but be in guard for a common defect—flashes that don’t pop up. The camera has a hot shoe so it’s not fatal, just annoying.

Pentax MZ-6 (XZ-L in the U.S.) 2002

The first Pentax with the Pentax P-TTL flash system and the last camera in the MZ/ZX series before the Pentax *ist of 2003, it incorporates an electronically controlled vertical travel metal focal plane shutter with speeds of 30 to 1/4000 sec and a 12 sec electronic self-timer.

Exposure modes include picture mode (portrait, landscape, action, night and closeup), program mode, Av, Tv modes, metered manual mode, bulb and TTL flash. The auto focus has 3 points and spot focus modes in single predictive and manual modes. An AF illuminator is also available to enhance low light focusing. The meter has a six segment TTL cell with a range of EV 0 to EV 21 at (ISO 100, 50mm f/1.4), and can be set for DX-coded film speeds from 25 to 5000 ISO or manual speeds of 6 to 6400. Exposure compensation covers a +/- 3EV in ½ EV steps. Three shot auto bracketing is also available in ½ EV steps, and the built inn flash has a metric GN of 11 plus red eye reduction. The finder uses a matte focusing screen with a 92% field of view and a 0.7x magnification. The motorized film transport delivers a framing rate up to 2 fps in consecutive mode, and it’s powered by two CR2 batteries.

Pentax MZ-M (ZX-M in the U.S)

In 1997 Pentax took a big gamble in introducing a manual focus camera in the M-series mold, essentially as a niche filler for the eternal K1000 that was finally discontinued that year. Basically, it’s a manual focus version of the Pentax ZX-5, minus the autofocus, built-in flash, or TTL flash metering. Regrettably, they also replaced the metal KA2 lens mount with a less durable plastic one, but at least they retained the 2fps motorized film transport.

Weight: 320g, body only.

The Pentax ZX-M or MZ-M is currently available for a piddling $35 to $50 in clean working condition complete with Pentax prime lens. It would have been a creditable replacement for the iconic Pentax K1000 were it not for that plastic lens mount, and it might still suffice as a K-mount backup camera or as your kid’s first analog camera.

Pentax *ist 2003

The last film SLR by Pentax, the *ist and its nearly identical counterpart the Pentax *ist D marked Pentax’s transition to DSLRs. A small, attractive 35mm SLR with an engaging feature set, and claimed to be to world's smallest AF SLR, it received a lukewarm reception by a public that was rapidly moving to digital.

Pentax *ist.jpg
The Pentax *ist, last in a long line of Pentax 35mm SLRs, is plastic fantastic, but it's small, cute, and performs a lot better than you might think.

A broad-spectrum consumer camera with a body constructed mostly plastic, the *ist uses the venerable K mount and is compatible with KA, KAF, and KAF2 mount lenses. It also supports M and K series lenses, but only in Av mode. Its electronically controlled, vertical travel, metal focal plane shutter provides speeds of 30 to 1/4000 sec plus B, flash sync at 1/125 sec; exposure modes include Av, Tv, and M, Auto, and picture (with settings for action, landscape closep, portrait, and night scenes). The penta-mirror finder has a 90% field of view at 0.7x magnification and incorporates a built-in -2.0 to +1.0 diopter control. Autofocus was good for its time but is slow and somewhat noisy by today’s standards. The TTL meter employs a 16-segment design that allows for matrix, center-weighted, and spot modes and has a sensitivity range of EV0 to EV21 at ISO 100. Film speeds from ISO 25 to 5000 can be DX-coded, and manually set from ISO 6 to 6400, and exposure compensation values of +/-3EV can be set in ½ steps. The built-in flash has a metric GN of 11 and the motorized film transport has a maximum framing rate of 2.5 sec, and allows for multiple exposures, timed exposures and the use of a remote trigger. Date models if the *ist have selected settings for imprinting Year, Month, Day; Day, Hour, Minute; Month, Day Year; or Day, Month, Year on the film.

Pentax *ist Specifications
Focusing and viewing:
Nine cross sensors sensitive to both horizontal- and vertical-line subjects with single-line sensors at right and left.
Full AF area, spot AF, or single AF sensors selected automatically or manually; single-shot mode with focus priority; continuous AF with release priority.
AF sensitivity EV -1 to EV 18 at ISO 100 with 50mm f/1.4 lens; AF aid-light in flash head; manual focusing option.
Noninterchangeable mirror prism finder with fixed screen showing spot metering circle
AF sensor areas shown in black except operational one lit by red LED
depth-of-field preview
built-in -2 to +1 diopter correction.
Shutter: Electronically controlled, vertical-travel, multiblade focal-plane shutter with speeds from 30-1/4000 sec plus B,
Exposure modes: non-shiftable program, aperture-priority, shutter-priority auto modes with auto picture; program and five subject modes lit on mode dial; metered manual exposure mode; correct exposure shiftable to focusing point; AE lock;
exposure compensation ±3 EV in 1¼2-EV steps
three exposure bracketing ±3 EV in 1¼2- or 1-EV increments
unlimited multiple exposures
12- or two-sec self-timer, the latter with mirror lockup; audible ST and AF signal
Date and time: built-in time and date printing; 17 custom functions.
Metering: 16-segment evaluative metering, center-weighted or spot from EV 0 to EV 21 at ISO 100 with a 50mm f/1.4 lens;
provision for remote infrared and electronic cable shutter release
lighted rear LCD screen.
Loading and winding: Autoloading, winding, and rewinding with auto DX film-speed settings; manual ISO 6-6400; single-frame or continuous advance to 2.5 fps.
Flash: Pop-up flash covers angle of 28mm lens, retracts automatically when power is turned off; X-sync at 1/125 sec; ISO range 25-500; fill flash; slow shutter-speed sync; redeye reduction; high-speed and wireless sync possible with proper Pentax accessory flash units.
Size & weight: 122 x 84 x 63.5mm (W x H x D), 335g, body only
Batteries: Two CR2 lithium batteries.

The Pentax *ist looks rather cheap and delicate and its silver finished plastic body does not exude the ruggedness of earlier similar sized Pentax cameras like the ME and MX. Also, its penta-mirror finder is not as bright or crisp as the excellent pentaprism finders found in other Pentax models. However, it’s versatile, kind of cute, has a metal lens mount and tripod socket, is easy to carry, fun to shoot with, and is capable of fine results with the right lenses. At a price of $50-75 body only it’s a good value even if you only use it a backup camera, and your teenage analogue acolyte will love its perky retro looks.

Thanks for this--after I got my LX bodies I pretty much ignored other Pentax bodies until I went digital in 2004. I did look at the MZ-S at the photo show in NYC, but didn't love it and it became obvious that digital was coming not too long after that. Most of the other bodies you mentioned wouldn't have withstood my usage or lacked features that I needed. Swapping a pentamirror for a pentaprism was never an option for me since I didn't care about the small savings in weight and cost but definitely cared about the quality of the viewfinder which both the LX and MX had in spades. Interestingly, I think that even Pentax's lower end DSLRs have come with pentaprisms in contrast with both Canon and Nikon DSLRs that my students have used where the deficiencies of a pentamirror behind a slow kit zoom lens are quite obvious.

With all of the above, though, I agree with you that most of these cameras would be a great value for someone starting out today with film, particularly when compared with what I think are vastly over priced Pentax K 1000's on the used market. While the K 1000 was a great deal when sold new, they have become a bit of a cult camera in recent years and are priced accordingly. There's nothing wrong with them, but other models offer more for the money.
 
I have a Super A that sits alongside the MXs. An excellent camera with a great viewfinder. The push button shutter speed adjustment isn’t a problem as I mostly use aperture priority. I can ecen use the modern 40/2.8 DA lens in shutter priority or program in this camera. The P50/P5 also has a fabulous finder and is underrated.

Unfortunately, the MZ/ZX series suffer from a weak plastic part which means most are now broken. The MZ5 was nice to use while it lasted.
 
Thanks Jason for this excellent article. I didn't know much about any of the later Pentax cameras after MX and LX.

A couple of questions I've always been curious about: how the hell are you supposed to pronounce "*ist" and what marketing genius came up with that name?

I'm right there with you on that one. The *istD wasn't a bad DSLR for its time but I'm sure that the model name didn't sell any extra cameras.

I totally agree with you on pentaprism vs. penta-mirror viewfinders, the former being far superior. However I have put some plastic fantastic SLRs to pretty hard use and most have stood up remarkably well. For example, I've run several hundred rolls through my Konica TC-X (100% polycarbonate body except for the lens mount) with nary a whimper. It even has a pentaprism viewfinder albeit not the brightest I've ever seen and mine is fitted with the superb 40mm f/1.8 Hexanon AR lens.

Thanks very much for your kind words. "ist" means "is" in German so I guess you could pronounce is that way, but since it's a K-mount camera that starts with a (*) I guess you could call it a "star-kist"--but isn't that a brand of tuna? Alas, I don't know the name of the marketing genius who came up with *ist, but I can tell you that George Eastman had a better idea when he dubbed his point and shoot of 1888 the Kodak, an abstract name he chose because it can be easily pronounced in any language.

Fascinating. My limited hands-on experience with Pentax MZ/ZX models has been positive, and there are certainly many "fully working" examples currently offered for sale. Can you (or perhaps another knowledgeable Pentaxian) tell us which "plastic part" you're referring to? Otherwise this comes off as an unsupported generic condemnation.

An extract from a relatively recent post on Pentaxforums:

“The dreaded day has arrived and my Pentax MZ-5 is now suffering from the infamous mirror return problem. It started with a slightly longer reset after an exposure and quickly progressed to the mirror not resetting every third ot fourth frame. It occasionally stays up and will only release when the camera is switched off. I understand this is caused by a plastic cog splitting on the mirror drive motor, the repair of which is way beyond my capabilities so it looks as though it will end up on the well know auction sitte for sale as 'Nor Working - for Spares or Repair'.

I have owned several MZ models, all of which suffered a similar fate. They are repairable with a new brass cog but it is beyond my capabilities and not really economically viable. I believe the MZ-S, MZ3 and possibly MZ6 have better mechanicals.

Loved the MZ5n when I had one and it was working - I could use the DA40, which made a very compact kit.
 
I got a ZX-M for cheap some years ago and it's a decent little camera.

The P3 -- my mother had one in her later years of travel and it did the job well for her. My regret (and I was not in a position to do anything about it) was that she traded her very complete, well-used Leica IIIa setup for it, a high school graduation gift (!). Too bad I couldn't have just bought her the Pentax in return for her giving me the Leica gear (which included a Summar, many filters, and Rapid Winder).

I've had a few as well, with the MZ7 being my favorite
The dreaded plastic gear death is closer every day :(

Also the P30 suffers from the same weakeness as the ME (mirror box strut)
 
Besides the problematic plastic part MZ/ZX series cameras incorporate a frightening number of internal moving parts made of plastic.
Pentax repair specialist Eric Hendrickson refers to these as "Plastic Pentaxes"; they were the first Pentax SLR models he stopped servicing.

The Achilles Heel as mentioned is a plastic part; once it breaks camera body no longer functions.
Pentax once supplied an upgraded replacement made of brass. Alas this part is no longer made.

Later production may incorporate the upgraded part, however only disassembly can confirm this.
MZ-S bodies labeled PENTAX Corporation are a better bet than those labeled ASAHI OPT. CO., LTD.

IMO Pentax P series cameras are a better choice for those seeking an inexpensive Pentax K-mount body.
