Nikon D200 compared to D70 and Fuji S3. All shot JPEG with default settings. Nikkor 50mm f1.8 stopped down to f8. D70 pic upscaled and S3 downscaled in PS CS2 (bicubic). Notice heavy S3 "normal" sharpening and mild D200 sharpening.
Not a very fair comparison since one is downsized (giving it an advantage) and the other is Upsized (giving it a disadvantage) but I guess to get the exact same shot, theres not much else you could do.
