<p>I took the lens to an authorised repair shop here in Singapore, and he told me they see this thing often. He attributed it entirely to the weather, and said it happens after being in the heat for a few years. He urged me to keep it in a place that doesn't get so hot. He will replace the cover (US$ 130 or 200 including internal cleaning), and the lens will be as good as new. Thanks again for all your help. </p> <p>Erik</p>

<p>Thanks everyone, it makes sense that it's some form of solvent, I just can't figure out what. Unlike my more utilitarian lenses, I've treated this baby like it's porcelain. Trying to think if I ever took the lens to India, which is the only place I really use insect repellant. Also, it seems evenly distributed across the whole rubberised paint, not just where my hands have been. Anyway, it's not a huge problem, just leaves my hands black and sticky, like touching fresh tarmac on a hot day. I'll pop by Canon, and see if there's anything that can be done.</p>

<p>Here is a photo</p><div></div>

<p>The lens looks great cosmetically, save for a few cracks in the coating behind the groves on the lens barrel. The front focusing ring is absolutely fine, no stickiness at all. I guess it should be possible to replace the outer barrel, which is kept in place by 6 small screws.</p> <p> </p>

<p>I live in a hot climate (Singapore), and recently, my 85 1.2 (first version) has started to give of black sticky marks on my hands every time I use it. The whole lens seems sticky, it's like the rubbery paint has gone permanently soft. I'm sure it has something to do with the heat, but I keep it in a room that holds normal room temperature. Also none of my other lenses do this.<br> Has anyone experienced something like this. and is there a safe way to clean it? Obviously, the lens is out of warranty, but I am considering taking it to Canon.</p> <p> </p>
