Well, I found that on the ST 20/4,5 and the three examples of the K20/4.0 that I had (still have one) the sharpness at the edges diminishes substantially, to the point of a soft blur in some cases. I've made a lot of pics with those lenses, and when the size gets up there, that soft blur becomes quite noticeable. Unacceptable! Could I have had a total of FIVE poor examples? Doubtful ...
Since I could get a fair sum for those lenses, I took the money and ran. The K18/3.5 seems to be quite a bit better in that regard. [EMAIL PROTECTED] wrote: > Are you serious about the K20mm f/4 being lousy?
