Originally posted by Sailor As others have said, the resolution increase in going from 6 to 10 MP is quite modest and the price in lost high iso performance is pretty high - at least based on what I saw with my DS2 and K10D.
For whatever reason, the K200D and K-m both seem to improve on the noise performance of the K10D (different ADC, other differences in circuit path, also differences in JPEG engines for those who shoot that way).
I disagree with the prevailing opinion on the difference in resolution between 6MP and 10MP. It's not *huge*, I'll grant, but definitely noticeable. More detail without cropping, and "noticeably" more cropability.
Perhaps more significantly, I find the extra pixels mean that I can - if I choose - apply more aggressive NR to my 10MP images (K200D) than I could my 6MP images (DS). With no NR applied, I'd call their noise performance similar - K200D captures more detail, and when viewed at the same size as a DS image, very similar amounts of noise. I like that - more detail, similar noise. But I also like that if I so choose, I can apply more NR to the K200D image to yield one in which the detail has been smudged away to resemble the DS image, but there is *less* noise. I can get much cleaner images at ISO 3200 or even 6400 (push processed equivalents) than I ever did with my DS for any given level of detail.
Anyhow, FWIW, no way would I have bought the DL in the first place. Not because of the sensor, but because of the lack of SR and SDM. Seems that was a camera just begging you to upgrade from day one. I'd upgrade to a camera with SR in a heartbeat. But it wouldn't particularly matter if it were K100D Super, K200D, K-m, or K20D. K10D could be worth a look too, but for me, it's kind of an odd man out. Others, I recognize, feel that way about the K200D. All comes down to what you value, I guess.
