    Hey guys, just got my Jupiter 12 from ebay yesterday, old Russian rangefinder lens. I thought it'd be fun to do a comparison between it, and a fairly well regarded modern lens.

    Obviously in terms of pure performance its a silly comparison, but I thought people would be interested in how the old lens compares. Especially since it's so cheap, and easy to adapt on the Full Frame A7 series. It's something I haven't seen yet, and think it would have been helpful when i was making the decision to purchase. Hope you guys enjoy!

    I'm not an expert in comparisons, but I tried my best to keep things comparable. They're just OOC JPEG files. Click the images to see them fullsize! (you may have to select 'Original' at the bottom right corner of the image):

    Jupiter 12 35mm f2.8 @ 2.8 1/50th 800 ISO
    Sony FE 35mm f2.8 @ 2.8 1/50th 800 ISO

    Jupiter 12 35mm f2.8 @ 2.8 1/100th 800 ISO
    Sony FE 35mm f2.8 @ 2.8 1/100th 800 ISO


    What do you guys think? Although the Sony is much sharper, I think the images from the Jupiter 12 look quite pleasing. Plus its pretty fun to use and about 1/8th the cost of the Sony :p Let me know if you guys have any questions about the lens, i can try my best to answer. I don't think there's as much info about adapting it as there as there is for the Jupiter 8.

    Well first, welcome PotatoBoy! Are you from Idaho, by any chance? As for your comparison, I agree, those old Russky lenses are fun to play with. But your first two photos pretty much tell the story, don't they? Everything but the center of the frame on the Jupiter is, well, er... character? :D

    I made exactly the same comparason, and i fully concur.
    If you shoot the jupiter on a film Leica, the result is quite different. Her the Jupiter really shines, even in corner performance.

    Interesting,.......the J12 is the Soviet copy of the Ziess Biogon which was designed nearly a century ago. It's a good performer for general photography although Soviet quality was very variable. However, to properly see it side by side with the Sony you need to stop down a couple of stops when it will probably compare quite favourably........

    What is really interesting is that, not only is the J12 NOT a retrofocus design, it also has that weird back element that virtually touches the film/sensor. From what we have been lead to believe there should be horrible phenomenas apparent, but actually it's very respectable.

    The J12 is a TINY lens which weighs little and costs the same,....An excellent landscape lens when you are carrying everything over hard terrain....However, filters can be problematic due to the deepset construction.

    Pretty much nailed it. A fun lens, but nothing close to the 35mm Sony.

    And welcome.

    jup12 wins the cool award, no contest :) the f/2.8 blurry field curvature on the sides adds emphasis to centered objects, which is something that you can't get with the fe35.

    the michaelfoto pic indicates that it cleans up nicely on the sides when stopped down, what a cool shot.

    thx for posting these pics.

    I have to state that it is not only stepping down that makes the difference. It is mainly because oldfashioned film accepts a much steeper angle from the lens than the sensor, In case of the Jup 12 its so close to the film/sensor that it allmost touches.

    yes, the wider the rangefinder glass is, the more problematic it is on these cameras... here is a wide shot of the jupiter 12 on an a7, still weak on the outer edges, but the aperture isn't listed:
