I just got rid of my D80 in exchange for two D70S bodies with the better metering and hopefully no ''hot pixel" issues .
BUT , the high iso is a bit scary compared to the D50 . Is it mainly a sensor thing if they are different sensors ?
I was wondering if by shooting in RAW I could clean the images up a bit better and get closer to D50 output ?.
Does anyone have any samples of D70/S images taken at 800-1600 iso that have cleaned up quite nicely ?

I can actually clean up iso 800 and even 1600 shots quite nicely . I don't think sensors have made as much difference as processors in this regard .

The sensors are the same, although the steppings might be different and have minor improvements here and there. I think most of the improvement is due to the newer and better image processing engines though. I have no complaints at all on my D40 up to 800, will use it at 1600 and not even think twice about it, and is still passable at 3200, way better than my D80!

Some reading for you. Also, click on Letkeman's link and go to her gallery. Scroll down to the technical stuff. Good discussions of high ISO shooting, using Neat Image, etc.

Thanks for that link... gives me something to think about. I use NN, but haven't made the time to play around with my own settings. I downloaded the D70s profiles from the website, but have had mixed results.

I did some prints at different iso levels on my D40 and iso 800 doesn't look much different to 200 . I notice the D70 only has "long exposure NR" and no other noise reduction settings . Last night I managed to get some ok results at 800 after noise reduction in photoshop .

Its going back at bit now, but I tended to feel the D70s was decent up to about ISO640 then started to fall apart.

The D50 I felt could hit ISO1250 (auto ISO) and it was still clean, much less chroma noise.

I personally felt the D70s was better than the D200 for noise, I felt that started to break down at ISO320 (bird feather detail loss).

It has its weaknesses but I think it is a better camera than the D80 when you take into account impotant factors like metering .
