comment:After selling my first copy, I bought a second. The second copy is the sharpest one yet--sharper than my RS.

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 is supported by in-body lens compensations. "JAPAN"

This second example is pretty sharp wide-open. There is also little distortion and pretty flat focus plane.
