Oh, forgot to mention. If you really truly decide to keep up with this, see if you can pick up a dead Polaroid Land or small folding camera and use the bellows. It will definitely last a whole lot longer than the bag from personal experience. If you can find a short extension tube in a Canon mount, you can replace the body cap with that. Just tape the bellows to the lens on one end and the short extension tube to the other -- I recommend gaffer's tape; less messy in the summer months -- and, voila!, instant shift-tilt! Have fun!
