Anyone can be an amazing photographer - but there is a distinction between a camera nut, and a photographer, to this end, Ken Rockwell makes a really interesting point:

"You need to learn to see and compose. The more time you waste worrying about your equipment the less time you'll have to put into creating great images. Worry about your images, not your equipment."

You can guess which category I feel this fellow falls into.

I hope he got a great deal of pleasure building his system - it does look very impressive (if not downright pretty), but it doesn't make me think any more, or less of his photography.
