| comment: | A nice looking copy in original packaging with original hood, missing original lens caps. "LENS MADE IN JAPAN" This is a large lens. It looks very similar to the 24 and 28 mm F1.8 EX DG lenses. This copy is better aligned than the other EX DG primes I've tried or any of the other full frame ultra wide angle lenses. It is decently sharp wide-open in the center. The Minolta 20 F2.8 has a much flatter focus plane which is probably better for many uses of an ultra wide prime. This works quite well for small indoor rooms. |
