Pixel for pixel, the 12-megapixel Nikon D5000 has scored better than the Micro Four Thirds cameras on these particular crop elements, but the Sony finally exceeds it in every area but the red leaf pattern. Despite its soft appearance, the Sony NEX-3 does eliminate the chroma noise in the shadows better than the D5000, and the mosaic image, while not as rich looking as the D5000's rendering, has more usable detail. It's pretty close, though.
The Sony NEX-3's 14.2 megapixels stack up nicely against the Canon T1i's 15.1 megapixels. Overall, the T1i is a little softer, but with fewer sharpening artifacts. I prefer the Canon's treatment of the background shadow, even though it leaves some luminance artifacts. The extra noise makes it look more natural when printed. Where the Sony NEX3 has a clear advantage is in the red leaf swatch. The NEX-3 makes something of it, while all the T1i can manage is an unreasonable facsimile.
