Popular Photography & Imaging has posted a test of the new Nikon D40x, the 10-MP sensor upgrade of the D40, written by Dan Richards. Here's a taste:
"Noise suppression was generally better than the D80's and much better than the Rebel's. As ISOs increased, the D40x's resolution exceeded that of the Rebel. Its noise levels of 0.9, 1.05, and 1.05 at ISOs of 100, 200, and 400, respectively, would qualify for a Ridiculously Low rating if we had one. (They all rank Extremely Low.) Noise reduction is applied steadily but unobtrusively at higher ISOs. At ISO 1600, noise was only Very Low, while resolution dipped by less than 5 percent, still Excellent. This is great performance—especially for $799."
There's also a fairly extensive but perfectly useless samples gallery—useless because it's impossible to tell anything about image quality from such tiny JPEGs. Although they do discuss image quality in the article.
As an aside, I have to admit that this camera annoys me. Here Nikon has a back-compatible lensmount, and it goes and makes the smallest, lightest DSLR...and then makes it so you can't put small, light primes on it. Bugger it! Probably its target market won't mind, though, so if you're in the demographic, maybe you'll want to take a look. I'd spring for a D80, myself.
