A Breed Apart: Leaf shutter 35s wth lenses faster than f/1.7!
Two are rare, two aren’t, and two are easy to find and quite affordable!
By Jason Schneider
During the “Golden Age of Rangefinder 35s” that peaked in the ‘60s, there were literally dozens of Japanese-made, non-interchangeable-lens 35mm rangefinder cameras fitted with fast normal (45-50mm) lenses in the f/1.7 to f/2 aperture range. All had leaf shutters, most featured range/viewfinders with parallax-compensating field frame lines, and many had built-in CdS-cell meters, providing non-TTL autoexposure and/or metered manual exposure. The reason this type of camera was able to flourish is that, at the time, it offered photo enthusiasts something akin to the Leica shooting experience at substantially lower cost, albeit without the ability to switch lenses.
Well, to paraphrase a hackneyed metaphor, “Nothing exceeds like excess,” so a handful of intrepid Japanese manufacturers decided to up the ante by offering leaf shutter 35mm rangefinder with even faster lenses, with apertures like f/1.4, f/1.5, and f/1.6. From a marketing perspective, this strategy was hardly a great success, but it resulted in some fascinating, if somewhat ponderous, cameras with outstanding performance parameters and impressive low light shooting capabilities.

Yashica Lynx-14E with 45mm f/1.4 Yashinon-DX lens is big, roughly the same size as classic Nikon F with plain prism and 24mm f/2.8 Nikkor!
The Kallo 140 introduced by Kowa Optical Co. in 1959 certainly foreshadowed the trend that Mamiya, Yashica, and Konica were to embrace but technically it’s an interchangeable-lens camera with a leaf shutter behind the lens, like the Voigtlander Prominent I and II, and the Aires-35-V, which offered 50mm f/1.5 and 45mm f/1.5 normal lens options respectively. I call the Kallo 140 (which was, from 1960, rebranded as the Kowa 140) an “ILCINO,” an “interchangeable lens camera in name only.” Why? Because only two lenses other than the standard 50mm f/1.4 Prominar were ever made for it, the rare 85mm f/3.5 Prominar medium tele, and the virtually unobtainable 35mm f/2.8 Prominar wide-angle. Here’s the lowdown on this truly exotic beast:

The exceptional and elusive Kallo 140 sported a 50mm f/1.4 Prominar lens, the fastest ever fitted to an interchangeable lens, leaf shutter rangefinder 35. The camera, which was introduced in July 1959, is a handsome, beautifully made, medium sized rangefinder 35 measuring 5-3/8 x 2-7/8 x 3-1/4 inches and weighing in at a hefty 2 pounds 1-1/4 ounces with standard, amber coated, 7-element, 4 group 50mm f/1.4 lens. Its viewfinder features a pair of true projected, parallax compensating yellow frame lines for the 50mm f/1.4 and 85mm f/3.5 Prominar lenses, with the outer edges of the finder defining the field (sans parallax compensation) for images shot with the 35mm f/2.8 Prominar. The leaf shutter that sits directly behind each mounted lens is a Seiko SLV with MX sync, and shutter speeds of 1-1/500 sec plus B. Both shutter speeds and aperture rings (to f/22) are locked together, but unlike other systems using the infamously inconvenient LVS system, uncoupling them is easy—just push the lefthand “ear” of the aperture ring as you turn it, and it won’t drag the shutter speed ring along with it. Brilliant!

Kowa 140, rebadged c.1960 version of the Kallo 140, is shown here with 50mm f/1.4, 85mm f/3.5, and 35mm f/2.8 Prominar lenses.
To interchange lenses on the Kallo 140 you press a small spring-loaded tab on the underside of the lens, turn the knurled ring in the middle of the barrel 60 degrees counterclockwise, and lift the lens off. At the rear of the lens is a spring-loaded aperture coupling tab, and outboard of this tab there’s a chromed brass rangefinder coupling tab that simply moves in and out as you turn the focusing helical. Mount the lens on the Kallo’s beautifully machined 3-lobed external bayonet and the aperture tab enters an arc-shaped slot in which it couples to the aperture ring, and the rangefinder cam contacts a rounded end pin that couples the lens to the rangefinder system—simple, elegant, and ingenious. According to Japan Camera Industry Association (JCIA)] records the Kowa 140 sold for an initial price of 25,800 yen ($72 at the insanely favorable official exchange rate n 1959!), and its 50mm f/1.4 Prominar lens is a Sonnar type. Prices vary widely, but the Kowa Kallo 140 with standard lens has recently fetched $700 at auction and a complete 3-lens outfit in mint condition was offered at $2,800.

Mamiya Super Deluxe of 1964 with superb 48mm f/1.5 Mamiya-Sekor lens. It has CdS metering and a parallax compensating range/viewfinder.

Mamiya Super Deluxe f/1.5: The Mamiya Super Deluxe is a series of high-end, noninterchangeable lens, leaf shutter rangefinder cameras introduced in 1964. The models with 48mm f/2 Mamiya-Kominar and 48mm f/1.7 Mamiya-Sekor lenses debuted in August; the version with the 48mm f/1.5 Mamiya-Sekor lens was announced in November. All three models have Copal-SVE leaf shutters with speeds of 1-1/500 sec plus B, MX sync via a PC connector, a built-in self-timer, and a cold shoe. They all feature big, bright, high magnification range/viewfinders with true projected, parallax-compensating frame lines, a CdS metering system with cell mounted above and to the side if the lens, and manual center-the-needle metering with indexes in the viewfinder and atop the camera. The meter was designed for 1.35v mercury cells and must be modified to give proper readings with current 1.5v batteries. Robustly constructed, and nicely finished in an assertively rectilinear post-deco style, all Mamiya Super Deluxe cameras feature excellent optics, and the 7-element, 5-group 48mm f/1.5 Mamiya-Sekor is capable of outstanding imaging performance. Models in pristine condition with the coveted 48mm f/1.5 lens go for about $400.00 to $550.00; examples fitted with the f/1.7 or f/2 lens are user-collector bargains that fetch around $150.00 apiece.

Yashica Lynx-14 of 1965 has magnificent 45mm f/1.4 Yashinon-DX lens and CdS metering system with center-the-needle exposure setting.
Yashica Lynx-14 and -14E: The original Yashica Lynx 1000 introduced in 1960 had a 45mm f/1.8 Yashinon lens, a built-in selenium meter and a top shutter speed of 1/1000 sec, one stop faster than most other leaf shutters. In 1962, the Lynx 1000 was upgraded with a CdS cell metering system and dubbed the Lynx 5000. Three years later, in 1965, Yashica took the Lynx concept to an entirely new level, releasing the Yashica Lynx-14, sporting a humongous 45mm f/1.4 Yashinon-DX lens, a sophisticated high-performance 7-element, 5-group design that’s the fastest and one of the sharpest lenses ever offered on a noninterchangeable lens rangefinder 35, and dropped the top shutter speed to 1/500 sec. Finally, in 1968, the company brought forth the Yashica Lynx-14E (labeled IC to denote its integrated circuit), which has the same impressive f/1.4 lens, but features an upgraded CdS metering system with a more sensitive, higher voltage meter cell, and over/under indicator lights in place of the Lynx-14’s precise but less rugged center-the needle system. Both the Lynx-14 and -14E have the same great automatic parallax correcting range/viewfinder with "Magic Spot" rangefinder with bright orangey-yellow field frame lines and well-defined rangefinder patch. The Copal SVE shutter in both models has speeds of 1-1/500 sec plus B, a built-in self-timer, and MX sync, with X at any speed, very useful for outdoor fill light. There’s a PC socket on the right side near the top, but neither model has a hot shoe. Film speed settings range from ASA 10 to 800, and there’s a little sticker on the back to remind users to press the chrome button labeled “switch” (it’s on the lower right front of the -14E in shooting position) to turn on the exposure meter. The port for the CdS cell is on the upper part of front of the camera, next to the range/viewfinder windows, so exposures must be manually compensated when using filters, a minor inconvenience.

Yashica Lynx-14E of 1968 was the last of the breed. It retained the superb 45mm f/1.4 Yashinion-DX lens, replaced meter needle with lights.
Both the Yashica Lynx-14 and -14E were designed to take mercury batteries (the Lynx-14 took a single PX625; the Lynx-14AE took two PX640A cells) and must be converted to provide proper readings with current alkaline or silver oxide cells. Since both cameras are completely mechanical except for the meter, they remain fully operational sans battery power. The last Yashica Lynxes are awash in character and their 45mm f/1.4 Yashinon-DX lenses are superb, but these are big, hefty camera s(the Lynx-14 measures 5-1/2 x 3-3.8 x 6-15/16 inches and weighs in at 30 ounces). The good news: You can pick up a clean fully functional Yashica Lynx-14 or -14E for around $75.00 to $125.00—the lens alone is worth the price. Just make sure the seller offers full return/refund privileges.

Konica Auto S1.6 released in 1967 is essentially a Konica Auto S2 with a faster lens, a superb 7-element, 5-group 45mm f/1.6 Hexanon.
Konica Auto S1.6: Unveiled in 1967, the Konica Auto S1.6 is basically a Konica Auto S2 with a 1/3-stop faster 45mm f/1.6 Hexanon lens, and the last member of the very popular Auto S series (the later Konica S3 was really the top-of-the-line Konica C35 series and dubbed “C35 FD” in Japan). The Konica Auto S1.6 is fitted with a more sophisticated 7-element, 5-group lens in a Copal-SVA 1-1/500 sec plus B shutter and has a built-in pull-out shade, and a hot shoe. It’s also the last Konica rangefinder camera of its era to offer full manual exposure plus the signature shutter priority autoexposure mode pioneered on the Konica Auto S models. It therefore remains useable even without battery power. The meter employs a CdS cell at the top of the lens I.D. ring, thus automatically compensating for mounted filters, reads out the camera-selected aperture in shutter priority AE with a needle and index in the viewfinder. It’s powered by a 1.35v PX625 mercury battery so it will require modification to work properly with current 1.5v alkaline or silver oxide cells. Its big, bright range/viewfinder has projected frame lines that not only provide automatic parallax compensation, but also correct for field frame size, the reduction in angular coverage as you focus closer—a unique capability in this class of camera. Solidly constructed, with excellent balance, ergonomics, and impressive on-film performance, the Konica Auto S1.6 is a great user camera that’s a phenomenal value at the current price range of $75.00 to $125.00 for a clean working example.
