I take it from your comment on +-10 your not really sure what or how to calibrate your camera.?

On my K-x I never used auto focus lenses, I got them with my IIs 4 weeks ago so no, I have no idea about calibration of the lenses/camera.

Hi Aidan,

First you have to exclude focus error. That's the hard part, especially when not in a testing environment. Figure out AF microadjustments. Also, I have a 3rd party focusing screen on my K5 (the ee-S) that way i know where i'm focusing. Be patient with fast lens, it's far from easy.

The Sigma 50 is supposedly a very nice lens, sharp wide open and vith very nice bokeh, thanks to its large front element. (I say supposedly as i've never used one).

Show us a few shots, we'll be able to help more.
