For the benefit of those folks that are not mind readers it would be nice if you would label which camera corresponds to whatever side of your example above (my apology if I\'ve missed an identifier somewhere)
I think it\'s implicit that the 1Ds3 is the slightly nosier one on the left.
No, 1Ds3 on right! Sorry I didn\'t provide identifiers, but to my eye there is so little between the cameras at iso 12800 that who cares which is which?
The point of posting this file is to illustrate that most people\'s beliefs about the effects of pixel contraction are based on per pixel analysis, which is thoroughly misleading.
It\'s my opinion that the G11 sensor was going to be better than the G10 one regardless of whether it was 10 or 15 Mpixels. Engineers don\'t sit on their arses all day, after all.
The issue is whether reducing pixel count to 10M provides any real benefit over 15M. Those that believe it does only have for evidence a groundswell of web opinion based on the incorrect per pixel analysis. Those of us who are more skeptical that reduced pixel counts provide any great benefit can provide some evidence that image quality is mostly a question of date of production and size of sensor: all of the current full frame cameras have about the same high iso performance and general image quality, and they are all clearly distinguishable from the crop current sensor cameras in that regard. In brief, what I\'m saying is sensor size matters, and sensel size doesn\'t (much). For evidence look at _all_ contemporaneous cameras from Nikon/Canon/Sony/Olympus/Pentax over the last ten years. That\'s why to me, Canon reducing the number of pixels appears to be a matter of pandering to the delusions of the market rather than a genuine advance in engineering. And one things for sure: given a good lens, a 15 Mpixel G11 would probably have taken _sharper_ pictures than the 10 Mpixel one.
