Just Posted! Canon EOS 50D in-depth review. Canon's EOS 50D is essentially a 40D body with a newly-developed 15 megapixel sensor, a 3.0 inch VGA screen and Canon's updated imaging processor, the DIGIC 4.

As you might imagine, we've had a closer look at this. Find out more after the link. Review now updated using the final version of Adobe Camera Raw 4.6.
