Buy the camera you'll use, not the camera you want.
I see too many photographers worry about their gear over capturing the image. As photographers we love gear, we love buying it, talking about it, reading about it and writing about it. Owning, researching and showcasing photography gear in itself is a hobby. I've met so many photographers with far better and newer gear than me. Amateurs normally have better gear than me. But I'll tell you one thing, I'm not afraid to use it, and sacrifice my camera if I must for that perfect shot.
