Re: Yikes! The rumored Nikon D800.

tests between D3s and D3x show a better lowlight performance. means: better high iso IQ. i suspected that the pixel size is playing a major role, but with your remark about i am not sure that this is all. will check that.

i agree, 16mp is just a number and more resolution generally is better, but:

i dont need 3x mp at all and i cannot believe that you'll see better IQ on a 30mp sensor than on a 20mp sensor (technically same generation).

lets not forget the fact that the smaller the pixels, the more shake is amplified. true?

my 16mp vote was stupid. but i'd prefer a 20-24mp FF sensor with 2 crop modes (1.2 and 1.6).

The difference in pixel size between the D3s and D3X has nothing to do with the low light performance. that is brought about mainly by the higher quantum efficiency, which Nikon has also achieved with the small pixels of the 1 system sensor.

i'd prefer a D4s (16mp) with (at least) 1 stop better lowlight performance over a D4x (35mp).

If the 35MP camera is based on the 16MP DX Sony sensor, you will not have a stop better lowlight, it's quantum efficiency is already close to 50% and its read noise very low.

but i have to admit, that a good resolution is also something that manifests in IQ. the question is what is enough. to me, a 5D3 with improved 21mp would be interesting, but perfect with 16mp.

16 is just a number, no real reason why it should be better that 21 or 24. generally, more is better.
