This is the same shot taken using the Konica Minolta Dynax 5D at ISO 1600. The exposure was 1/2000th at f8. What's interesting is that using identical ACR 3.4 settings, ACR insisted on an exposure adjustment of -1.3. That's based on the highlight values up to the clipping limit in the file. Again, zero sharpening and NR have been used, and a linear curve is applied. Shadows, brightness and contrast are all auto, WB is As Shot, and saturation is zeroed. The file has been enlarged to the same overall size as the A100 shot - 10 megapixels - using Bicubic Smoother interpolation. This is to show a direct comparison in sharpness and detail as well as noise. I find the comparison enough to make me wonder whether my A100 has a defective sensor, or at least one at the very limits of QC/performance control. How can such a great difference exist otherwise?
