I echo the advice to be careful about the tape you put on your lens.
My 24mm f/1.4L lens has a lot of sticky residue from countless times that its focusing ring has been taped, and I wish I had been able to avoiding using electrical tape, duct tape, etc., on those occasions when I had no other choice. It is probably going to lower resale value by a few hundred dollars, on a lens that would otherwise look like an 8 or a 9 out of 10.
Suggestion: Use only gaffer tape: "While related to duct tape, it differs in that it can be removed cleanly because it uses a synthetic petroleum-based adhesive."
Rubbing alcohol will get the stickiness off without a trace. Just soak a cotton wool bud and wipe away, it will probably take a few goes but isn't difficult. Alternatively you can buy just the rubber grip from Canon for not much and fitting is easy.
Thanks! This is very helpful. I would have to apply some pressure about right on top of the cracks above and below the focusing ring, and some alcohol would definitely be released into the crack as a result. Any chance that the alcohol could harm anything within the lens?
Thanks again for at least giving me more courage to try what I've been too afraid to do yet.
