Originally posted by ScooterMaxi Jim Most folks perceive the chroma noise as more film-like - and find it far more acceptable than luminosity noise. Of course, that's a personal choice (although you see a lot of folks say they prefer the noise look of the K20D - when consistent and not banding.
When I was talking about how ugly the noise is produced by the K20D, I was not thinking so much about the chroma noise as the sprinkled with pepper appearance the K20D images have. I also shoot with Sony, Minolta, Olympus, and Nikon; and I have never seen any of their cameras produce anything like that.
The K-5's noise is probably the most film grain appearing of all the digital cameras I have. I was pleasantly surprised. But boy, if you shoot at high ISO's and have large fields of a uniform color, then the K-5 can sure produce some funky effects with those fields that are not appealing. One just has to recognize what can happen when photographing and work around it.
