I bought the adapter for my A-mount lenses / Minolta on the new A7. Fits perfectly and all the functions are available. Of course, APS-C lenses do not reveal the full-frame sensor from the entire area, but can be corrected automatically or in the post on the PC. Certain lenses are entirely unsuitable, such as the 18-270mm Tampron. By contrast, the Tamron 10-24mm works very well. From focal length 16 practical no limitations on the full-size can be seen. Super function even old Mintolta mm lenses and of course Sony A full format as my 70-400mm G lens. Overall, a great thing.
