this is why i have not posted for a (long) while
to me, most of my photos look out of focus, using my Sigms 17-70mm F2.8-4.5 DC Macro on my K7
As in the image attached, the focus is on the student, but he looks blured and everthing else behind him is sharp?
F/L 53, 1/500, f4.0, ISO 125, manual mode, Multi-Seg metering, Autofocus , Auto W/B, Fine Sharpness2 +1, Shake Reduction On, JPG 14m ****
Any ideas, any Pentaxian live near me that could take a look at my gear to see what they think?
