Question: Can I use the Sony 100mm f/2.8 Macro Lens with this adapter on Sony Nex 7?
Document: This lens adapter works exactly as advertised. I use it on a NEX 7 with the 16-50 2.8 SSM, and the 70-200 2.8 G. Focus speed and accuracy is great. If you have a NEX and would like to use Alpha mount lenses, this is the ticket!
Got a new adapter but with a old Minolta 100/2.8 Macro and Sony 35/1.8 (Easy Choice) both 2nd hand. Both are very very good.
My current A-Mount lens collection is as follows (all fully compatible with my LA-EA2):1. Sony 50mm f/1.42. Minolta 85mm "G" f/1.4 (OH. EM. GEE. This is the FIRST lens you should get. Trust me.)3. Minolta 135mm f/2.84. Minolta APO HS 80-200mm f/2.8 (I just got this and wow. WOW.
This adapter is worth getting We have a nex 5n & nex 7 we got two. Focus is faster now we use sigma lens which has lens stabilization with la ea2. Only gripe missing DMF which is a desired update hence 4 stars.
Sony LA-EA 2 Adapter for NEX 7. Great Product works with 8pin Contact & 5 Pin Contact older  Minolta & Newer Sony  ALPHA Lenses. Feels good Balanced when mounted on CameraDOES NOT HAVE AUTO FOCUS ASSIST FOR VERY LOW LIGHT FOCUSING. Wont focus unless a small LED light is on the Subject Or any thing.I think this function will work with all E LENSES. [...]
A key advantage to this is that while PDAF AF points will be used to focus, the focus peaking feature also highlights areas that are in focus.6-In AF-C mode, focus peak &#8220;assist&#8221; is unavailable.Overall focusing speed is as fast as one can expect. I tested the adapter with Minolta 200/2.8 G APO HS on my NEX-3, and my blazingly fast dog on her maiden visit to a dog park.
I was having problems focusing using the ea1 adapter and my Sigma 105mm macro, using manual did work though. I found this and gave it a shot since I had the lens, this made an unbelievable difference. The focus is faster than it is with an lens without an adapter.
Great product. Love the way I can use my other lenses with this camera now. Pictures are great with this adapter and my other lens.
I had been using Sony LA-EA1 adapter to use my A-mount lenses on NEX. It worked well especially since I prefer to use manual focus. However, a couple of my A-mount lenses that could be used on NEX weren&#8217;t very friendly due to their tight focus gearing (&#8220;High Speed AF&#8221;). So I ventured into LA-EA2 territory.The adapter itself is built well, like the LA-EA1.
I made the mistake of asking for a lens for Christmas to fit my Nex camera. It was the only lens that zoomed to 300. But, even though an alpha lens, didn't fit without an adapter. I was outraged at Sony's price, which was more than the lens cost, and almost as much as the camera cost. amazon's price was considerably better, but still very costly.
Answer: The SAL-100M28 correct?I have never tried it personally, but it should work.  Have read reviews of people using it.  Someone said it was a little on the slow side (but that was an older firmware, and I am not sure he knew what he was talking about).
