優點:
1. A good choice for APS-C format; and
2. Can be a back-up lens for full frame, but should fix on 18mm.
缺點:
1. No Minolta feelings; and
2. Noisy focusing gear.
評價:
The only wide angle solution within my days in Dynax 7D, because my 20-35 became 30mm. The lens is totally not Minolta style, it is a Tamron.
