Jupiter-12 35mm f/2.8 (L39)

Have tested a Jupiter-12 35mm f/2.8 which has a M39 mount (Leica screw mount, L39)

Below are some of the test shots taken with this lens.
The B&W pictures are analog and are taken with a Zorki 6, AGFA CINEREX (X-ray film) and developed in X-tol.

My review has more and hires images and can be found here if you're interested: Jupiter-12 35mm f/2.8 (L39) Review

Beautiful images, but I wonder, how do you mount this lens on a modern dslr camera :/

You can't...the J-12 was designed for rangefinder cameras with a short registration distance*. When mounted, the rear element is only a few millimeters from the shutter. This protruding rear element is also a problem with many rangefinder cameras. With some there is interference with the TTL metering. With others it will not clear the shutter curtains or light baffles. The J-12 may be adapted (with varying degrees of success) to many mirrorless cameras, but again the proximity of the rear element can result in poor performance with some sensors.

Why these sample images were posted here is anyone's guess. The J-12 cannot be adapted to any current or past Pentax camera.


* Leica thread mount (LTM) and Contax/Kiev mount

I love the Jupiter 12 lens. Like a lot of Soviet glass, it provides beautiful results.

True. I especially like the sample #2. The grain, which I don't especially like from the film days is actually doing it a favor here. It looks so much more 3d because of it. Someone could just easily ps it out, but it make the image much worse.
