Sticky Rubber Help


New Member
Hey gang,

I've got a 28-70mm 2.8 lens. It's pretty old, I actually just bought it brand new. I'm aware that most old Sigma lenses with the rubber coating eventually get tacky/sticky due to humidity.

Here in the DC area it is typically quite humid during the summer.

Anyone have a solution to prevent this stickiness?

Aside from cutting off the rubber......

Thanks in advance.

I live in Houston...and have not had a problem...yet...but I have heard this thoughts would turn to maybe re-coating if it is an expensive lens...if not...bustoner's idea sounds the way Sigma has extended there warrantee period on all non-EX lenses to a total of three years....
