Lite citat:
"
The Alpha 900 native resolution is the maximum size in the list of exported sizes now. While ISO 3200 is not going to beat a Nikon D3 (etc) when viewed pixel for pixel, 24.5 megapixels versus 12.2, when you reduce the size of the A900 image to closely match the D3 size results in similar conditions give the A900 an edge in detail resolution - and slightly less mushy noise."
"
Is this good for an ISO 3200 image processed using these parameters? I believe it is. I have used the Nikon D3 and D700 in similarly low light conditions, but mainly the D3. I know what the noise of the D3 looks like, and have praised its high ISO performance particularly at 6400 and above - at the time of its launch, nothing else went above 6400 or did 6400 as well. But that the D3 is ‘noise free’ is a myth even at ISO 400."
"
Now in my book, at the very similar 11/12 megapixel size the D3 has a much softer resolution and shows a more distinct (but film-like, and evenly distributed) noise grain. I think the A900 downsized to 12 megapixels will display higher detail resolution, and less noise before post-processing, than a similar Nikon D3 processed from raw. JPEGs are a different matter; the Alpha 900 ‘Fine’ JPEGs are not pleasant, and get worse as you increase the ISO setting. That is why, after experimenting with Extra Fine JPEG (much bigger than a cRAW!) and RAW+JPEG, I shot everything using cRAW."
