The almost orgasmic response to the announcement of the Koday DCS-14 is getting a little silly at times, even on this site. Statements are being made to the effect that the resolving power of the Kodak stands head-and-shoulders above the Nikon, even to the point of matching actual film resolution.

Fiction: The Kodak resolution at 14 megapixels equals or exceeds film resolution.
Fact: Figures for the resolution of a full-frame 35mm negative vary, of course, but they vary from around 35-40 megapixels (theoretical) to 20-22 megapixels (real-world attainable). This information is all over the internet.

Fiction: The resolution of the Kodak is a big improvement over the Nikon.
Fact: While the Kodak has a full-frame sensor and would eliminate the 1.5 magnification factor, its resolution is actually LOWER than the Nikon's. Break out your calculator if you don't believe it. The Kodak, with 13.9 megapixels in a full-frame 24mm x 36mm sensor (864 sq mm) has 16,088 pixels/sq mm. The Nikon, meanwhile, with 6.1 megapixels in a sensor sized 15.6mm x 23.7mm (369.72 sq mm) has 16,499 pixels/sq mm.

For the sake of simplicity;
Nikon: 16.5k pixels/sq mm
Kodak: 16.1k pixels/sq mm

Yes, the Kodak has a lot going for it. Yes, it's built on a great body (custom-manufactured by Nikon). Yes, the full-frame sensor moves in the right direction by providing more information (NOT higher resolution) and eliminating the 1.5x factor. But we're not at the end of the rainbow, not yet.
