Pentax K-7 Review, Sample Photos and a Video Clip at InfoSyncWorld – Mike Perlman:
Pentax is one of the top manufacturers when it comes to image quality on the intermediate/semi-pro level, and we knew we would be capturing a few magazine quality shots here and there. At ISO 100, we experienced microscopic levels of noise, if it even existed. The new processing succeeding in reducing noise slightly, and noise is a difficult thing to stave off, especially with a high-resolution sensor. Colors were stunning, and the level of control we had over hues and tones was nearly overwhelming. The Pentax K-7 also captured images with razor sharpness, though we had to adjust the sharpness level on a few images in order to dial back the intensity. We also rarely encountered any fringing, and we achieved some of our best shots at night with awesome exposures, courtesy of a slow shutter speed.
