Add a focus marker to a Canon lens

I had a bit of leftover sugru so I added a focus marker to my 50mm Canon lens. The 50mm f1.8 is a great little lens and the cheapest one that Canon makes, as can be shown by its completely plastic construction. It also has no focus marks on the lens body so I decided to add one with a small piece of sugru, shaped into a nice little pointer. It's placed on the left hand side of the lens when attached to the camera so I can feel the sugru with my hand even when I'm using the viewfinder. By @solarmechanic, via sugru gurus (bit.ly/Oq0hd4)
