Kodak DCS Pro 14n Digital SLR Kodak's latest digital SLR brings full-frame, 13.7 megapixel resolution to market for under $5,000. (Review first posted 3/23/2003)

Boring Res Targets, ~100mm prime lenses on both cameras

These shots were captured using the Nikkor 105mm f/2.8 macro lens on the 14n, and the Canon 100 mm f/2.8 macro on the 14n. Different lenses, to be sure, but each is one of the very sharpest made by its manufacturer.

Here are the vertical resolution wedges (showing spatial frequency response along the horizontal axis) from the 2x target, shot with both cameras. These were shot with each manufacturer's ~100mm lenses, but unfortunately at an aperture of f/4.0, rather than the f/5.6 or f/8 that would probably be optimal for best sharpness. (I'd already had to ship back the 14n when I discovered that I'd shot with the aperture set to f/4.0, so had to shoot the1Ds example the same way so they'd be comparable.) You can still clearly see though, that the capabilities of the 14n do extend beyond the 2000 lines/picture height that the normal-sized 12233 target displays. I'd call the 14n's resolution here as somewhere around 2100 lines/picture height of strong detail, while the 1Ds shows about 1900. Here once again are links to the unsharpened versions of the shots for the 14n and the 1Ds.

Pro 14n Here's the crop showing spatial frequency response along the vertical axis for the 14n. The artifacts make it a little bit of a judgement call to decide where to peg the resolution, but I'd make it out to be somewhere around 1800 lines/picture height of strong detail. (900 lines on the chart.)
EOS-1Ds Here's the same crop from the 1Ds. Here the aliasing is a bit less discontinuous, but it's still a bit of a judgement call to say what the resolution is. I'd put this at about 1650 lines/picture height. (825 lines on the chart)

The Pro 14n does clearly outperform the 1Ds on the resolution target, which I guess is to be expected given the difference in pixel counts between them and the lack of an antialias filter on the 14n. The missing antialias filter does cause the 14n to produce stronger color moire artifacts at very high spatial frequencies than those of the1Ds, but the import of that (as well as of the higher resolution) will be up to individual photographers to decide.
