You do have a point there, in my experience all my lenses were out to varying degrees so I made an average adjustment for all my lenses with consideration for the one I used the most. The adjustments are so fine you bascially are adjusting mm at a time which is only really visible when shooting close up photography.

Very nice, I'm also an avid macrophotographer but I recently dropped my K10d and it broke. Luckily it is insured so I'm planning of upgrading to the K-7 now.

I had the same problem on my 16-50 DA*, it can only be fixed by adjusting the focus of the CAMERA and not the lens. You either need to have the camera and lens calibrated by a Pentax service center, or you can do it yourself. I downloaded a small application from the web, plugged my camera into the computer, ran the debug application and accessed a new submenu on my K10D which allowed me to adjust the focus of the lens through the software. Now it focuses crisp and clear. I recommend searching the web for this application : GX10-K10D Debug Mode Control and follow the instructions (AT YOUR OWN RISK I might add).

Morning,
The spam is unfortunately still a problem. I am a 25 year user of Pentax equipment but a new forum member and I have just received 2 scam emails. I have reported it to the help center, but thought I would post a comment here too.
