Received a message from Francesco Bollorino about an issue that his testing of the Sony NEX VG900 camera uncovered; that the supplied lens mount adapter the LA-EA3 works in full frame mode with no vignetting but does not have auto focus features. While the older LA-EA2 lens mount adapter allows for crop mode shooting without vignetting but does have auto focus features. The LA-EA2 is for APS-C sensors so pops up vignetting in FF mode on the Sony VG900. Perhaps a marriage between the two lens mounts would give the VG900 users an adapter that covers the camera’s full frame with full auto features?
There is a second language at play here, so some of the labeling on the video is incorrect, but you get the gist.
