I have been trying to look into this, but haven't been able to reach any conclusions yet. The tests I did last week was done with the K20D on a tripod and using the 2s self-timer. So alas, I'm left with a set of test shots with an awful lot of weird noise. I have learned about the firmware update adressing that problem, but haven't got around to update the camera yet. :-(
Though off-topic for a Pentax group, there was a very interesting discussion at www.foto.no last week (in Norwegian, unfortunately), discussing the dynamic ranges in raw files from various cameras. With the Canons in particular, but also the Nikons, it seems one can pull down details from highlights that seem to be blown by up to 2-2.5 stops, judged from the chimping screen. It was argued quite forcefully that underexposure was to be dreaded much more than overexposure, because of the lousy S/N ratio in the deeper shadows. Apparently, the K10D does not provide much leeway in the post-processing compared to what appears on the chimping screen, but nobody tested the K20D. It's tempting to speculate that the switch to a CMOS sensor in the latter could make a big difference... :-) Jostein 2008/6/26 Boris Liberman <[EMAIL PROTECTED]>: > Hi! > > The review just published on DPReview and mentioned here mentions that > K20D has 9.0 Ev of usable dynamic range whereas according to their > test of K10D, it has only 7.3 Ev of DR.
