I'd like to see some anecdotal reports from the various adapters being used on NEX (now alpha) E mount bodies, especially, the new full frames a7/a7r. I hope photographers migrating to or augmenting their current system camera with the Sony a7/a7r will use this thread as a resource.
I plan initially to go with a Sony LA-EA3 to use with the good selection of alpha mount primes I possess for the a7r I have on order. As one can see from the link, this adapter only auto-focuses with lenses with on-board motors, but will provide lens diaphragm support for all "a" mount lenses. Sony also has the LA-EA4, that offers autofocus for all alpha mount lenses, including "screw drive" lenses.
I intend to acquire a collection of "m" mount lenses in the near future. The "fast" series from Voigtlander look interesting (21 f/1.8, 35 f/1.2, 50 f/1.1, 75 f/1.8). There are several "m" to "e" mount (or NEX) adapters available. The Metabones "speedbooster", will of course be of no use on the full frame a7's. This adapter from
Hawk's Factory would seem to offer a solution to the long minimum focus distance prevalent in RF lenses.
Please post the adapter solutions that work for your system lenses and NEX/alpha 7 body.
