So... I've been thinking about selling my D90 for a D700 a lot lately. I'm gonna be honest, photography is strictly a hobby of mine and I've never made a dime from my photos (unless you count a free lunch from a friend who wanted a print of one of my shots ). I am a gear head and I think a lot of my desire for a D700 stems from my just wanting the latest gear. With that said, I do feel the improved AF and high ISO noise of the D700 would be great assets that I would appreciate for my photography. Am I crazy and irrational for even considering buying a $2700 camera for a "hobby"? Not to mention there's a part of me that thinks one should be able to produce photos of a particular quality to be "deserving" of a camera like that... and I don't know if I'm quite there yet.... Feel free to talk some sense into me... cause I think I need it. Let's hear your thoughts!
