I have cameras I haven't even shot yet. But then I also appreciate the equipment in its own right. That being said, I almost never take more than two cameras. Three lenses are about my limit as well. Most often it's one camera, one or two lenses.

I'm not a pro, don't hope to be a pro. But too much equipment, and I find myself spending all my time fiddling with my stuff, and not taking pictures, or enjoying the time out with the camera.
