Jupiter 8-1??

As far as I can tell just a regular Jupiter-8. Is on the Princelle 2nd ed. book page 143 as K575 circa 1990's manufacture with black anodized finish.
 
it looks like one of the last batch of Jupiter 8's.
made as a replacment lens or to be sold as a faster lens for the Fed 5 as the Zorki 4K was
last made in 1978, and this J-8 is a 1990 vintage.
either way, with shipping cost, that is a pricey J-8 by todays standard.
 
Is it a Rangefinder lens? - I won an Industar 50-2 on E-bay (it was only £2) as it was on the RF section and there was a load of text about Industars and Zorkis / FEDs , when it got here it was an M42 lens 🙁 .. To be honest, the £2 was worth it for the extra feedback and that the front cap fits my Jupiter 8 (inside the front ring but it fits ;-) and I don`t have any M42 lenses at all thesedays - so now I have one, there`s no excuse for not buying a £10 Spotmatic to relive my youth ;-)
 
It's definitely rangefinder -- 39mm LTM. The jupiter 8 is very common in that mount. I'd never seen or heard of a Jupiter 8-1, so I was curious if it was something interesting. Aside from the serial# on the side and the 8-1 designation, it looks exactly like the black J-8 I use on my bessa r.

J-8 were made only for rangefinders. The equivalent f/2 aperture objectives for Zenit were the Helios (58/2).

By all means get an M42 SLR. (GASsing you here 😀) The Industar-50-2 is an excellent 'pancake' Tessar-type lens. There are always nice Zenit around where the I-50-2 will fit nicely.

Thanks Jay, I wasn`t sure as I`d never heard of Industars in M42 either a week ago ;-) it hasn`t got the Auto Aperture setup which the Helios lenses have and that probably confused the seller, definately not a lens for TTL metering (Stopdown only) despite being relatively moden (made in 1978) though my knowledge of M42 glass is very rusty, apart from keeping a Zenit TTL and a couple of lenses in a case for years in case I needed it, I replaced my entire M42 setup with K mount glass in 1982.....

I have to admit that if I saw an original 60s Zenit going cheap I`d grab it, I had the TTL of course and it was a very good camera but if I was going THAT "modern", and start playing around with M42 glass again I`d get another Spotmatic 🙂 .

I`ll have to get an M42-Nikon adapter and see how this little Tessar performs anyway 🙂

Well, given the difference in lens registers, I think you'll be hard pressed to find an adapter (one that allows focusing at infinity, anyway)

Too new Paul , that`s just an "E" with the Light meter missing 😉 - may as well pay £20 for a mint Spotmatic as get a Zenit as new as that 🙂 ..

Philipp - the lens is an M42 SLR lens, not a Rangefinder one so it would be fine on the Nikon SLRs with an F to M42 adapter - I tried the Helios 58 on a Sigma SD9 a while back using a K to M42 adapter and apart from the lens being Pants (it was the later 1981 version) it focussed fine ..

Will have to be the spotmatic I think , As all the early Zenits 1,C,3,3M and early E's and some B's are m39 if I recall correctly , I can do you a near mint TTL if you like ?

😉 😀 😀

Register for Nikon F (on the camera) is 46.5 mm, for M42 it's 45.46mm ==> no infinity focusing. The adapter needs corrective optics. Have you ever seen a M42 [lens] to Nikon F [camera] adapter?

""The adapter needs corrective optics. Have you ever seen a M42 [lens] to Nikon F [camera] adapter?""

No, only seen the PK ones which I used on an SD9 which is basically the Pentax K mount hardware wise .. no corrective optics in that, but I guess as M42 was used By Pentax in the beginning, they`d make their SLR mount backwards compatible for registration..

Paul - I gave away a mint TTL recently, I forgot that not just the earliest Zenits were L39 threaded SLR lenses and some Es / Bs "suffered" also ;-0 . Ahh well, FSU SLRs aren`t as much fun as FSU RFs anyway 😉

The Industar-50-2 is one of the M42 lenses which do work well with an optical M42-Nikon adapter. This is the lens which I first used with an adapter on my Nikon-mount Fuji S2 DSLR. Other lenses have issues with these adapters. The Pentax Takumar 50/1,4 for instance will have its focusing movement hampered by the optical element- lens can't move back far enough to focus to infinity. Other lenses (namely the wide-aperture ones f/2 or faster) tend to create flares and haloes, at least with the digital sensors. The extra glass at the rear of the mount tends to throw reflections back into the sensor and cause flare blooms around bright highlights. Helios lenses tend to do this. Stopping to f/4 largely eliminates this problem.

On film, the flaring is not too obvious, though some 'blooming' can still be observed in the brightest of highlights.

Some say that the optical element can reduce the lens' resolution. It may be true since adding an extra element to the system can alter the lens' designer's best intents 🙂. I haven't seen any significant deterioration of detail though, other than the aforementioned flaring. The optical element in the adapter is a weak negative lens which acts like a very low-powered lens teleconverter. A 50mm lens will be converted to something like a 51 or 53mm.

BTW, the lack of auto or preset diaphragm facilities, or even click-stops for that matter, in the Industar-50-2 isn't really a disadvantage. On cameras which allow stop down metering (such as the Canon EOS), the lens aperture can be turned up or down to whatever the shutter needs in daylight shooting situations. No need to check the aperture scale at all, unless DOF considerations are important.
 
Thanks Kim and Jay - I remember the adapters to use FD glass on EOS bodies had an optic in there and they were patchy at best.. If I had all the Takumars I owned once, I`d give it a try but jot for a slow Industar - anyway it gives me an excuse to pick up another Spotmatic and relive my youth ;-)
 
If you want a Pentax or Fujica M42 body, I can probably help.
