Sigma Lenses rubber body

[junkai21]

Hi Bros,

Do you all have an issue with your Sigma Lenses? Im on a 4 year old 18-200 and the focusing and zoom rings have white powdery stuff which is tough to wipe away due to it's rubber texture. It's not fungus and i can confirm it's dirt. Do you all have similar problems? Im not sure if other Siggy lenses use the same rubber or not.

Also to note, do u feel that sigma lenses' body, u can scratch it and it gets very visible white line? :dunno:

I'm guessing it could be sweat residue. I'm also having it on my Canon lenses. The white lines on the body area also on my Sigmas. Dun think can remove. Why you want to scratch it anyway? :sweat:

There is a thread on exactly the same topic here: http://www.clubsnap.com/forums/showthread.php?t=579511

Unless you dont use the lens at all, the rubber part will still turn white after some usage. So you can either clean it regularly or just leave it alone.

What grease? The grease is left by the manufacturer? Is it part of the lens?

Are you sure it is grease? From what I know, camera manufacturers glue the rubber to the barrel. The grease should be inside the barrel, not outside. If I am wrong, please correct me
