The adapter specs are for 52mm to 67mm, but I managed to get it on 49mm without any problem.

I bought this at the forums. Not sure where to get it in shops.

This thing is fantastic.

The adapter doubles as my left hand grip. It's light. Very, very light.

AF is fast as expected. Half press, confirm, half press, confirm. I have it set to spot focus. Wide focus mode isn't as effective, and goes bonkers sometimes. Local focusing works as expected.

The cons? Battery life. This thing sucks battery like Charlie Sheen does a line of coke. And, you do not get DOF preview. During live view, everything is at wide open aperture. So a little practice is required if you are shooting at smaller apertures. Because of this as well, the shutter produces two distinct sounds (w/front curtain on). First sound is the aperture closing down, and the second the shutter moving.

Overall: If you have some A-mount glass, and a NEX-5N, get this adapter. I run around now with the NEX-5 and NEX-5N together, in the same bag.

I got my entire set from Uncle Chin @ Studio Zaloon.

1)5N Body - RM2180
2)LA-EA2 - RM980
3)SAL35F18 - RM690

It was quite funny; he had no idea Sony Style had the EA2 adapter in stock already. If I didn't ask him about it, he would think it was only coming in January. So he brought in stock the next day for me. Excellent service.

Great news although not 100% confirmed....new firmware updates for NEX3/5/C3 which unable the LA-EA2 usage !!

how much is the ea2 adapter? whre did u get it from?

Which meant new store also facing the 'clicks' problem? the old store not yet finish?
