My wife is a pro and loves her Nikon D200. But lately we’ve been wondering if Cannon is a better camera. We’ve come into some money and she is debating whether or not to switch. She dosn’t have many lenses so she could make the switch easily. She mainly deals in Black and white fine art and portraiture. I am looking for an opinion as to what is the best for Black and White Fine art and Portiture. Nikon d200, D2x, D2xs or te Cannon line of Digital SLR’s. All opinions are welcomes. I am particularly interested in the opinion of you pro photographers out there.
