Pentax News and RumorsDiscuss rumored Pentax or photographic news (that upcoming Pentax full-frame K-5) and official Pentax announcements here! This is a discussion on K20D Noise Comparison against A700, 40D, D300, D3, part of the Pentax Cameras: Pentax News and Rumors category, related to d3: Comparision Chart Link

Wow. I've never looked at the output from the other cameras as I have little interest in buying one, but these seem to tell a story. There is a slight problem of differing image crops, makeing it a little hard to do 'perfect' comparisons....but nonetheless my thoughts follow:
A700: Strong anti-alias (AA) filtering and/or noise reduction resulting in loss of detail. 40D: Complete obliteration of detail in image processing at all ISO levels D300: Weak AA filter and low NR preserves detail at the cost of some noise (mostly Luminance, present uniformly across the luma spectrum...shadows, midtones and highlights) D3: Some anti-aliasing, but otherwise great.
K20D: Weak AA filtering and noise reduction preserves details. Higher ISO shows luminance noise mostly in the darker areas, with very little noise in the midtones and highlights.
It looks to me like the K20D is second only to the D3. I'm impressed.

My thoughts exactly. The D3 is the clear winner in the high ISO category, but the K20 is a close second and the rest fall away rather quickly. I am really disappointed in the 40D. It is the lowest resolution so I thought it would have low noise, but that's not the case. Good job Petnax!
I've been looking to replace my stolen K10d and have been scouring the net for more comparisons like this. Though I know it's early days yet, early firmware, not-scientific, etc... it's quite exciting to me that the K20d might live up to it's hype in terms of IQ.
On a similar vein - I like the idea of a "(mostly) raw RAW", giving some of the PP control back to the photographer/image specialist. It might save some battery juice too. Given that I feel Pentax thinks more about the photographer than most other companies, I wonder if they will ever offer the option. Although, having a button for RAW++ (+++) might be a little wierd...

Frank.
There is a setting in the K20, where you state the amount of NR that you wanna use.
Pentax is definitely a photographer’s company, even if some people feel that they are too old school at times
Did anybody notice under the picture of Tokyo skyscrapers, it is marked ISO 80. I was under the impression the lowest ISO for the K20D was 100. What gives?
