comment:For the price I had to buy this. Stopped down a notch my copy has proven to be very sharp, except for the far corners, but if hasn't stopped me from enjoying this fun lens. It sits on my a700 perfectly, and while the combo is far from light, it is comfortable to use. The much complained AF/MF ring isn't that bad once you get used to it. Flare is something to be expected with a lens this wide, but can be avoided quite easily. All in all, a great prime if you can get it with a reasonable price.
