I work with Nikon since I started photograhy, for 35mm other brands for medium format.
When I had to switch to digital I kept goin with Nikon. Even if the size sensor was smaller than the 35mm film, crop about 1.5 as already stated.
But I have to say that Canon offers a better images quality (other the fact that they are so far the only one to offer a real 24x36mm sensor (1DsMark II at 8000$ and 5D at 3000$)).
When I talk about quality it is mostly about highlight and shadow and noise at high iso. Better dynamique range.
you should check
Luminous Landscape Forum (Powered by Invision Power Board)
I think this a really good forum. I compare it to this one. Most of the members are pros.
Also dpreview.com provide really good review.
If you have any question regarding digital capture, process, just ask.
