Hello John, I have both the K10 and K20 and the low light on the K10 is much worse, as you have experienced. The K20 and K7 have basically the same sensor so the low light performance between them is very similar. There are a few who think the K7 is better and a few who think the K20 is better. Be that as it may, the K-x is at least as much better than the K20 as the K20 is compared to the K10. Did I say that right. The step up from K10 to K20 is big, but the step up from K20 to K-x is even greater when it comes to low light performance.
Yes, the shot needs the little catchlight removed, as you noted, but overall, the need to image process for high ISO is significantly lower than with the K20. -- Best regards, Bruce Tuesday, August 31, 2010, 2:27:04 PM, you wrote: JS> From: Bruce Dayton >> One big difference for me was that with the K20 and earlier I really had >> to have good conditions (lighting, processing, etc) to make a high >> ISO shot reasonable.
