Jupiter 12 which one?

Jupiter-12 were only made in Kiev/Contax and L39/LTM/screw mount. For RD1 you need L39 mount J-12 and LTM to Leica M adapter, or (less conventional and more expensive) Kiev mount J-12 and Contax/Kiev to Leica M adapter.

Btw what is the longest focal length that R-D1 can use?

What do you mean ? framelines in viewfinder or the ability to focus long focal length lenses ?
 
The one on ebay says it's M39 mount for leica so I still need an LTM adapter?. Regarding the longest tele lens that I can use, like the 75mm or 90mm lens or even 135, is this doable with R-D1?.
 
You will need a screw mount to M adapter (LTM adapter) to use it on any M mount camera. The rear of the lens on a J12 is protuding very deep in the camera (the J12 is the 35mm one, the J11 is the 135mm one) and I don't know if it will fit inside the RD-1 (it fits in a M8 but barely), and metering will not be perfectly accurate as it protudes so deep inside the camera and close to the shutter blades.

Anyways, the first time you insert it into your RD1, be careful to see if it touches the shutter blades.

If you were refering to the 135mm one, you will also need a LTM adapter but won't have any metering issues. On a RD-1 it will be quite a long lens and will be hard to focus (and frame) accurately at anything bellow F8
 
if you find a J12, I highly recommend checking the serial. The older the better. Found that all older FSU lenses register focus much more accurately than the newer 80's lenses. First 2 numbers of the serial denotes the year... I had a 68 and it was really sharp.
 
I have just got myself a Jupiter 12 but haven't what year is it yet?
Before I mount it on my R-D1, could I just double confirm that if all version of Jupiter 12 will be able to mount on R-D1 & M6?
I don't want to take a risk on my R-D1 because I might have difficulties in getting someone to fix here in my country.

Thanks
 
The first 2 digits of the serial number is the year it was produced (19xx).

When I tried mine on my M8, I screwed it very gently and listened carefully to see if it would touch the shutter when screwing it in. It didn't so I proceeded with taking pictures.

However it protuded so far in the body that TTL metering ended up being quite inaccurate with it and the M8.
 
I do own a Jupiter 12 from 1991 and it works quite fine on the R-D1. But I have to control metering, which sometimes is far off and sometimes is fine.

Jupiter-12 works quite well on the R-D1, metering is an issue sometimes. The black version is said to be better than the chrome one. Just be careful not to touch the large protruding rear glass of the J-12, ALWAYS put it down upside down, otherwise the rear lens gets scratched!!

My J-12 mounts fine on my M6 without touching the shutter curtain, but I can't meter with it as it blocks the meter cell. (I can't remember what year it is - I don't have it with me right now - but it's a black 70s or 80s one).

Thanks for the info, I have checked mine, serial starts with 78...., so should be a 1978 edition.
Have tested few shots on my R-d1, so far so good.
