Originally posted by oldbagley Greetings to all, I hope this will go to the right place (ie - K10D club)! Please excuse any errors - I'm a bit confused as this is my first post.
I have been a long time user of the Samsung GX10 and really like how it feels and what it does, and recently acquired a GX20 (K20D equivalent) for use with longer MF lenses and higher ISO's.
I note that when shooting RAW, the GX20 produces images with very low saturation levels compared to Raw images on the GX10. When both are set to JPG, both produce good levels of saturation and colour.
My question is - Does anyone know if this 'poor' RAW saturation on the GX20 is normal and just a charateristic of the CMOS sensor when compared to the CCD item in the GX10, or might I have bought a 'lemon'?
Many thanks in advance for any thoughts you may have.

Its the characteristic of the GX20 CMOS versus the GX10 CCD, but not he characteristic of current CMOS sensors. I went from a K10 to a K20 and was actually very disappointed in what images looked like, even after post processing. Considering your dealing with a sensor built when CMOS technology was in it's infancy, it was probably to be expected. I don't think you'll be that thrilled with the GX20 at higher iso either. There really wasn't much improvement in noise until the K5 series. On my K20, iso 800 was about as high as I was comfortable going, which was about where the K10 topped out as well.
On a side note: Recent generation CMOS sensors are much better than the K10 CCD ever was, but not everyone agrees. for them there's the K10 forum.
