Need advice on Jupiter lenses and mount please

[StillSanj]

Hey gang. I am in Eastern Europe and I came across a bargain deal for Jupiter lenses. They are a Jupiter 8,9,11, and 12 and in mint condition I would say. The problem is, only the Jupiter 8 is in m39 mount and the others are a bayonet mount. I'm having a hard time distinguishing which mount they exactly even are.

I have a canon 70D and I believe it would be hard and expensive to adapt them to my 70D except for the Jupiter 8. However, I would really like to find a way to utilize them, as they are in such a good state and I love trying all my lenses not just reselling them, and with that mount I doubt their value is high even in mint state, so I might get more out of using them.

Does anyone have any experience with a similar situation and could give me advice? I also have an older nikon d100 which I believe might be easier to adapt to. I would really like to use them on my 70D but if not, any alternative input would be appreciated. The adapters for that seem to be expensive and scarce.

What would be the best and least expensive way to utilize these lenses? Would some surgery be possible to change the mount? You see my confusion so any input would be appreciated.

Also, on the m39 Jupiter 8- better to get m39 to m42 adapter or just m39 to eos?

Thanks guys.

Those i guess are rangefinder lenses in m39 and Contax-kiev mount.
All of them cannot be used on Canon EOS as the register distance is very short.
You can use J8, 9 and 11 on a mirrorless body.

Best and least expensive way to use them: a Russian film rangefinder camera.
Only digital is a mirrorless camera, but it can be expensive, especially if you want Full Frame sensor.

There are two types of adapter for the Contax/Kiev Bayonet lenses. Lenses that have their own focusing ring use what is called the external mount adapter which is a simple tube with flanges and is not expensive. That Jupiter 12 uses that kind of mount. The 9 and 11 may also, I am not sure as I have only owned those lenses in M39.

Lenses that don't have their own focus ring require an internal mount that provides a graduated focusing helicoid, which is why they are so expensive.

The Jupiter 12 has a rear element that extends deeply into the camera. It can interfere with the shutter and/or mirror of many SLR/DSLR cameras. To my knowledge it will work with a Contax or Kiev SLR and a Sony A7 full frame digital. You would be safer to insure it works with your camera before you try to mount it.

The Jupiter 8 uses a different back flange distance than Leica LTM lenses and generally needs to be shimmed to work properly on a Leica or Leica model rangefinder. That isn't a problem using it with a mirrorless camera however, it works just fine on my Sony A7 and A6000 using a standard M39 adapter. I expect that this is true on an adapted SLR or DSLR since you aren't using a rangefinder to focus the lens.

StillSanj,

The answer is very simple: As long as you are using your Canon SLR camera, you can forget all those Jupiters which are designed for the use on a RF-camera like the Jupiter 12, 3 or 8. Only Russian lenses with either M39/Zenit or M42 mount are without limitations usable on your gear.
There would be e.g. MIR-1 37mm or a Jupiter 11 135mm or 9 85mm (among some others) available in this mount. Be careful with the 85mm lens as they are not very different.
In other words: Only the heavy and huge ones are usable for you and all the very small and tiny RF ones are not compatible with a SLR.
