There seem to be conflicting opinions on the use of an LTM Jupiter 12 on some LTM cameras, such as the Bessa and the Canon P. Sometimes they work, sometimes they don't seems to be the conventional wisdom.
But what happens if you put an LTM to M adapter on a Jupiter 12? Will it "work" on a Leica M, RD-1, or Hexar RF body?
What about a Jupiter 3 for those of us that cannot swing a Zeiss 50/1.5 sonnar lens?

A J-12 worked happily on my M2, and the only 50mm lens I have for the camera is a J-3. The bulbous rear of the J-12 will interfere with the metering on those M bodies that have it.

The J-3 should work on any LTM body. If it's in good working order, which can take some luck or work, it's a very, very nice lens.
AFAIK, the J-12 should not be put on a Bessa body; the rear element can hit the shutter. I don't know how it reacts on the Cannon P. They do seem to fit on Leica M and LTM bodies, although the rear element blocks the meter on bodies that have one -- as Payasam noted.

Works on my Hexar RF. Seems to meter ok, at least in daylight (the only conditions I've shot it in). Does not work on my CLE or Bessa R2.
This is a lens to mount carefully on any camera as the rear element will press directly against the shutter on many and on the rest it is a hair's width away.

My J-12 works fine on my M2 and M6 with an adapter - but it does stop the meter working on the M6.
The reason they can hit the shutter on a Bessa is, I believe, because the Bessa has a double-shutter, with the front shutter further forward than the cloth shutter on a Leica (or FED/Zorki).

Newer J-12 models - the black version - can be used with Canon P.
