Here is a more controlled test comparing the two cameras. Note that my question is not "Do K20s perform better than K100s?" but rather "Is my K20 performing as well as it should?" Should I expect to see more difference between the K20 and the K100?
Same lighting, same subject, same lens, same f/stop, same tripod Three lighting situations, "bright", "medium" and "dim" semi auto exposure, K100 +0.7 EV to expose to the right (also with the K100 ISO 800 at 0.7, 0, -1 and -2 to compare pushed 800 with in camera 1600 and 3200) shot in raw Post processing in light room auto tone white balanced on the grey card in groups K100, at 1000x800 http://www.flickr.com/photos/ellarsee/sets/72157621756137388/ K20 at 1000x800 http://www.flickr.com/photos/ellarsee/sets/72157621756062718/ K100, cropped in tight http://www.flickr.com/photos/ellarsee/sets/72157621631845587/ K20 cropped in tight http://www.flickr.com/photos/ellarsee/sets/72157621631845587/ K20 ISO 3200 Exposure: 0.6 Aperture: f/5.6 Focal Length: 77 mm Exposure: 0.00 ISO Speed: 3200 http://farm3.static.flickr.com/2481/3742194472_2a6494a52f_o.jpg K100 ISO 3200 Exposure: 0.8 Aperture: f/5.6 Focal Length: 77 mm Exposure: 0.00 ISO Speed: 3200 Exposure Bias: +0.7 EV http://farm3.static.flickr.com/2481/3742194472_2a6494a52f_o.jpg K100 ISO 800 pushed 1 2/3 stops Exposure: 1 Aperture: f/5.6 Focal Length: 77 mm Exposure: +1.90 ISO Speed: 800 Exposure Bias: -1 EV http://farm3.static.flickr.com/2576/3742195532_35f085de3e.jpg -- The first step is learning to take great photos, the second step is learning to throw away ones that are merely good.
