    Hi,
    I am finding on the internet this lens

    BRONICA Zenzanon E II 75mm f/2,8
    at a decent price. I would like to know if you ever heard about such a lens as I was not able to find many reviews.

    I liked its size and how compact it make the camera look like (as well as the f/2.8)

    Regards
    Alex

    Bronica was (is?) a medium format camera. So the registering depth is long and so the combination of Nex and it it's lenses quite big. It may be quite usable combination for portrait work but not very practical for everyday work. Besides I think that there is no adepter for Nex available. Resolution may be quite low too.

    I've had one myself. It's for the Bronica ETR range of medium format film cameras [I use an ETRSi]. It's a good lens, a step up from the MC version although not quite as good as the later PE range [which I replaced it with].

    I'm not sure of the value of using it on the Nex though, it really would be unbalanced on a Nex body. Also the relative crop factor from 645 medium format to APS-C would mean the focal length becomes an equivalent 280mm or so whilst the apparent depth of field would drop from f/2.8 to around f/7.1 - if I've got my maths right!

    Still, if the price is right and you can get an adapter, give it a go and let us know how you get on!

    Your math is bit off. Focal length doesn't change, field of view does. 75 mm lens works as 115 mm would work in 35 mm but focal length doesn't chage, camera just crops it's image from the center. So it is irrelevant if the lens was intended for medium format or full frame.

    Btw, does anybody have suggestion for cheap medium format lens with focal length of 40mm? Intended use is a diy pan&tilt objective.

    Fair enough but that's why I wrote "equivalent"!

    I don't know of many cheap 40mm m/f lenses though, being wide angle they're relative more expensive, certainly my 40mm PE cost over £150 IIRC.

    Yep, that is the problem. As this is going to be a toy I wont put very much money to it. Maybe I will find a suitable one some day. Wide angle enlarging lens would be ideal but medium format lens would work too. I have a 50 mm meopta enlarging lens it may have big enough image circle. It is of course a telephoto with Nex so it is of limited use.

    Can you please explain the 35mm you wrote? If I buy this lens what I understand is that it will be covnerted to a 115mm. The price I found is quite okay so I wanted to try this as a manual lens to practice. I am not sure though if there are other things that I should take into consideration.... or where I would be able to find a converter for my nex.

    As 35 mm film camera, I should have written.

    The focal length of objectives doesn't change when you use it with adapter but field of view does if sensor/film size is different. So 75 mm medium format or full frame lens will have same field of view as a 115 mm lens in a full frame (35 mm film) camera.

    There seems not to be adapters from Bronica to Nex. There may be one to M42 but the combo would be quite unpractical. Those medium format adapters tend to be quite expensive too.

    Jupiter-9 will probably be much cheaper as you need one cheap adapter. There are some 70mm-210mm zooms that would be usable too but these have maximum aperture of 3.5 or 4. Or some 135mm lenses may suit your use. 85mm is unfortunately a very wanted focal length. I will get the Samyang 85mm/1.4 some day.

    Jupiter is a brand of a lens maker and Jupiter 85mm/2 was available in several mounts. I think that this article describes the mount:
    Contax rangefinder lenses - Camerapedia

    There seems to be adapters for it:
    Contax RF adapter (not Contax G) advice?: Sony NEX Talk Forum: Digital Photography Review

    And somebody is using this lens with Nex:
    Jupiter-9 black KIEV CONTAX RF 85mm SONY NEX-3

    Kiev-10 mount Jupiter-9 isn't compatible with nex!

    Most desirable mount is M42 but is going to cost much more:
    Jupiter 9 f2 85mm Russian lens for Sony NEX | top35mm.com
    (I don't know anything about above site).

    I will purchase Samyang 85mm/1.4. I think that it is much better buy but it is much more expensive:
    Samyang 85mm f1.4 IF MC Pentax

    But this isn't very high on list as I am quite satisfied Pentax 55mm/1.8 and Tamron 105mm/2.5 (and several zooms [Vivitar series 1 70-210/3.5 waits the end of chinese spring festival so that I can order the adapter for it]).

    For this lens you would actually need a Contax Rangefinder to NEX adapter, there are many available on ebay. There are several versions of the J-9, one for m42 slr mount, one for Leica thread mount (rangefinder), and the one you've found for Contax rangefinders.

    The Leica and Contax lenses are basically the same, differing only in the mount. The m42 version is much shorter and has a fatter body than the rangefinder lenses. If everything I've read online is accurate the m42 version does not perform all that well. The rangefinder lenses are pretty good though.
