Originally posted by biz-engineer Which shot are you referring to exactly? I'd don't get really over critical with my shots in terms of edge sharpness, I'm not really a landscape shooter, shooting people more often than not at wide apertures so all the edging is blurry. Even some of my landscape work is not that stopped down and has deliberate edge softness. If I was into urban and landscape more seriously I think I would be more aware of this particular issue.
I've noted that my FA77 and FA43 are both performing better at +10 Fine Adjustments also. Bought both from Pentax direct I should be able to get them to have a look at the glass I guess...
