comment:This is my second used copy of this lens purchased from individual sellers on eBay. I returned the previous one since the left side was very mushy. This one is better aligned than the previous one. There is less glow along high contrast edges and the corners look reasonably even. "LENS MADE IN JAPAN."

This lens has a great deal of focus plane curvature and chromatic aberration. It certainly doesn't fit the macro designation other than the fairly close focusing ability. It actually works quite well for portraiture. The rendering wide-open is very nice unlike the Minolta wide primes which are a mess in any out-of-focus area. Maybe the misalignment in this copy helps smooth the out-of-focus rendering?

The APS-C 30 F1.4 EX DC is definitely sharper especially in the corners as are the Minolta and Sony primes.

This lens is growing on me. The Sigma EX lenses may not be super sharp like their current Art series, but they do seem to have lovely rendering.
