comment:This is a fairly small lens, though much larger than the Minolta AF 24/2.8 and 28/2.8 primes. It looks a bit like a wide converter was added to the front of those lenses. The bayonet hood looks just like a scaled up version of the 24/2.8 hood. Like the 28/2.8 this lens seems to be supported by in-body lens compensations. "JAPAN"

Film wide angle lenses don't make much sense for smaller sensors. The Sony E 16-50 PZ OSS is sharper with less aberrations. This lens has a strange combination of attributes. Between focus shift from stopping down and rather poor performance wide-open, it is not a lens that is easy to get the most from. But there is also little distortion and quite a flat focus plane.

The little E-mount primes are much sharper as is the DT 16-50mm F2.8 SSM.
