I might be a bit one sided Alex but I have found the Canon 5D model, the original 5D a superb imaging Camera, with low signal to noise ratio.
It served me very well when i was imaging and i still use it now for normal photography.
They, the Cameras are very cheap now and one could pick up a very good secondhand one for about 400-500 dollars.
Anyway that is just my 2 cents worth, have to admit i don't know that mush about the Nikon models, I'm sure they too are very good Cameras
