DSLR bodies are VERY close in image quality and color. Shot side by
side all of the Nikon bodies shoot images that look quite alike when
printed side by side from NEF files. My D200 files are VERY close to
the D70 images. My friend's 30D shots are also about the same. I have a
friend with a Fuji DSLR (S3) and we agree that it's about the same
image quality as any of the other DSLRs. When pushed to low light
limits you'll find bigger differences in the sensor's capability. Under
most shooting situations they are so close that it's a stretch to
compare DSLR bodies to film. Most professional tests really go crazy
with 100% crops to see ANY difference that matters.
Choose a DSLR based on the lenses and ergonomics/performance. Ozzy's
lenses are fairly poor, but Canon does make some good glass. There is
also some 3rd party glass, such as the Tokina 12-24mm that beats all
others.
