I'm actually very disappointed with my K200D, it has all the functions I'll probably ever need and is built like a rock, it's also capable of taking better photos than I can.
I'ts big failing in my eyes is that because it's such a good camera I can't justify buying a K7.

I see you used the Pentax Macro focusing rail which, according to what I've read is very smooth and stable but is as scarce as hens teeth. At a rough calculation the steps between frames is less than 0.5mm, the Pentax rail is rack and pinion driven whereas, say the Manfrotto rail is screw driven.
My question, how controllable is the rack and pinion stepping, compared to screw stepping of say one turn between frames.

No, how can one ever be sure about anything, it's all subject to interpretation. Maybe I read it the way I wanted to understand it.

Hi Stefan, That's exactly what Dick said, each one is adjusted independently so that they agree with one another.

The only two worthwhile photos from an overcast and wet weekend in Swaziland.
Taken with K200D and FA 100mm f2.8 Macro.

For interest, is it possible to have a lens tuned or adjusted for optimal sharpness, I'm thinking in particular about my Pentax 80-320mm f4.5 zoom. I know there are better zooms available but I've got this one.
I've only used prime telephoto lenses and am a disappointed with the zoom's resolution and would like to get the best out of it. I don't expect prime sharpness.
