comment:	A somewhat rough looking copy missing the hood and caps purchased at an eBay auction from an individual seller. This lens has changed very little over time. The RS version adds more curved aperture blades and a rubber cover to the focus ring and that's about it. 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" This copy of the RS is a bit sharper than the original I have. It is still nowhere near as sharp as the tiny Sony E 20mm F2.8 pancake lens. There is a little distortion and quite a flat focus plane.
