Lint-Proofed My G12
Got my G12 back from Canon today, with a new lens assembly (the original's lens gears had been jammed by pocket lint that got in around the base of the lens).
Took off the protective ring that covers the bayonet mount for adapters and put it face down on an old lens cleaning cloth which happened to be red in color.
Traced the inner diameter of the ring onto the cloth with a pen.
With a scissors, cut a smaller circle about 1/8 of an inch (~3mm) inside the circle I had drawn, and a larger circle the same distance outside the circle I had drawn.
Laid the red cloth gasket I had just made onto the camera around the base of the lens.
Applied a glue stick to the camera-side of the lip of the protective ring that circles the lens and lays on the surface now covered with the red gasket.
Bayoneted the ring back onto the camera on top of the red cloth gasket, with a little cloth snug around the base of the lens.
The gap around the base of the lens is now occupied by a red cloth gasket that doesn't interfere with the lens moving in and out but does block lint from entering the camera - and marks mine as the first G12-L: after all, it has environmental sealing and a red ring around the lens!
