So, I was screaming mad when I learned that the D3's chip size was actually slightly smaller than the D2x (i.e., the D2x is 12.4MP, the D3 is 12.1; the D3 is, though, essentially full-frame). But, does it really matter? Well, that depends.
If you were someone who dropped $20-$30k on a medium format back, just to get a native resolution of 22MP, this camera's got to frustrate you, especially when you realize that the color depth of the Canon and Nikon is going to be so comparable to your MF back, that you'll feel comfortable shooting chocolate with these cameras.
So, what of the difference in chip size?
The image specs and lens choices are the same as outlined in the noise section of this piece. In fact, since we're all worried about the size of the Nikon as smaller than the Canon, I'm putting up the Canon iso3200 here first to compare to the Nikon files I'll be showing.
|Here again, so it's on the same page, is the Canon, at iso3200.|
|Here's the same Nikon iso3200 file, but it has been rezzed up to be the same size as the Canon file. No sharpening has been applied. It appears there is less noise, and it's smoother overall. I know it's not as sharp, but when you're so deep into this photo, either the viewing distance of the viewer or the reproduction abilities of the output device will all but take care of this concern.|
|Here's the same Nikon iso3200 file but it has been uprezzed and sharpened to my tastes. It appears equal to, or better than, the Canon image. In other words, by up-rezzing the file to the size of the Canon file, I can actually achieve a more pleasing final result than the native file results from the Canon.|
|Just for comparison purposes, here's the same Nikon iso3200 file as above, not uprezed, not sharpened. (in other words, it's the same file, just uprezzed, and then secondarily sharpened.|
These results, for me, essentially kill the megapixel issue for me. Size, with the proper chip and internal camera processing software, is no longer a comparison point for me. I'm sure we'd have problems if there was noise at the ISO's I need, because enlargement would yield more noise, but since that's not a concern, it's amazing what a 12.1MP camera can look like when compared to a 22MP camera. My yardstick had always been based upon a conversation I once had with an editor at National Geographic. We were discussing, very early on when it was not digital cameras, but the scanners being used to scan film - that a file that was 60MB at 8-bit was scanning at pixel-to-grain 1:1 using Kodachrome 25 as the benchmark. So, anything over 60MB was just increasing the number of pixels that hold one grain of film, and thus, is overkill/redundant. I see that, properly done as Nikon has, it's not an issue at 12MP.
