Re: For the 20-40 ED Limited lovers, a good review

No. But...

It's sad...but I've changed 20-40 to FA31. I can't get any predictable results from 20-28(29) mm focal range. 30-40 mm is excellent. Very good.
It seems to me my copy is decentering, but the service center says that everything is very good.
But...I had sharp right corner at 20 mm and very soft left corner and so-so center. I never had such results with my lenses for 34 year of my photo life.
I've tried to tweak AF, used MF, LV - no any predictable results.

Sometimes, I've got good photos at 20-29 mm, but rather often - no good. It made me crazy. I can't understand why there is so high scatter of results...
