I have a Canon 7D and many lenses, one for every occasion!
I love that it's built like a tank, shoots at 8 frames per sec (perfect for pet action), and the image quality is outstanding.
I don't love that you will soon be selling your firstborn for "that next lens." Lens lust is constant and real.
But if you are serious about photography, you cannot go wrong with this camera (it also shoots HD video!). I posted some sample shots tonight.
