Jozef,

You are right.These pics were a quickie to compare sharpness more than anything else so I enclose 2 images of a local church taken within minutes of each other, See clock. Both images (K1 31mm: SDQ 18-35mm) were under exposed but after some work on Photoshop the Sigma has blown highlights of the sky compared to Pentax.. In other respects the images are not too much the same. To me both images show how useless I can be on days of high contract light!!:-D

Did the Sigma image have blown highlights in SPP ?

I suspect you may have lightened the whole image in Photoshop, rather than just the shadows.

Scenes like this often benefit from a "double dog-leg" curve -- steep in the highlights and the shadows, and straight in between.
