Sounds like you mis-calibrated. How did you do the MF adjust?

Which light source - artificial light? What distance?

I own the a900 and in order to use the calibration data, IIRC the menue item must be left ON.

Camera was on a tripod, natural light, anti-shake off, mirror locked up, apture 2.8, distance to target 12 ft., 40 expousers -20.....+20.

+15 was sharpest.
