"Best" 35 or 50 mm fixed lens for Canon?

[quote name='decltype' timestamp='1326204520' post='14672']

Just wanted to note that there are plenty of EF-NEX adapters with built-in (mechanical) aperture control being sold on ebay for <$50. I have one EF-NEX, and one EF-m4/3. They both fit nicely, and the build quality is very good (they are made from metal).



I gave my NEX-5 away, though... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/rolleyes.gif' class='bbc_emoticon' alt='Rolleyes' />

An EF->NEX adapter is by definition electromechanical, not mechanical, if one wants to perate the diaphragm in the EF lens. In EF lenses the diaphragm is controlled electrically, or rather, electronically. If it is a mechnical coupling only, the only way to set the aperture is by using the diaphragm preview button on an EOS body, and dismounting the lens while holding the aperture preview button depressed, and next mounting it on the EOS->NEX adapter on the Nex body. That's rather awkward to do.



Of course, one could use an adapter with its own diaphragm, but that introduces a lot of distortion, because it is not placed anywhere near an optical plane of the lens, and apart from the vignetting it will likely produce. I'd rather use a not so good native lens, to be very honest.



I see the electronic version isn't available yet: [url="http://conurus.com/index.php"]http://conurus.com/index.php[/url]

I thought it was by now.



Kind regards, Wim
Gear: Canon EOS R with 3 primes and 2 zooms, 4 EF-R adapters, Canon EOS 5 (analog), 9 Canon EF primes, a lone Canon EF zoom, 2 extenders, 2 converters, tubes; Olympus OM-D 1 Mk II & Pen F with 12 primes, 6 zooms, and 3 Metabones EF-MFT adapters ....
