I have just received this new DA 15 Ltd (almost new) lens and tested it with roughly 100 pics from landscape to close ups and I find:
the shots taken at close range, in this case "artificial flowers" show perfect focus at about 2 feet away. I also took some of very small print, at close range ... all perfectly focused.
the shots taken during landscape sessions do not look very good: almost slightly OOF overall.
There is absolutely no way I can get remotely close to the quality of the photos from this thread:

Since I dumped most of the pics, I don't have them to show here.
My question: what is the best way to "fine tune" the AF so that it is consistent at both close range and "landscape" mode.
I haven't touched the fine AF adjustment for BF/FF yet, nor didI think this was necessary because the close up shots were bang on.

P.S.: I haven't tested it on my K5 yet. But that shouldn't be an issue I think.
