Beautiful build quality, all-metal, it inspires the strength, the 2 mounts on the adapter, Sony side as Nikon side are well finished, no play, although farms.
One curiosity is that the copy I received does not look like the photo on the product file, the toothed ring is silver, not black, the inscription above is not A1-NEX but "Big_is A1-nex "(see picture) ...
I recommend this to all pocesseurs adapter Sony E mount and Nikon who would ride their objectives above, just know that indeed, only the A and M modes operate as it should, you can take pictures with the other modes, but the result is capricious ... Ah, we also need your Nikon lens has an aperture ring, in my case, the Micro Nikkor 60mm f2.8, a wonder!
Last important detail, since the MaP is manual, an update is not a problem at all, but what is difficult is to not move once the item is, for indeed, unlike a self MaP, the point is "locked" the shutter button half way, but again, any movement forward / backward and up / down changes the point! Naturally, this has an impact only if the opening is very large when the POC is weak and sensitive.
