Sigma Lens Question

[Doug]

This is not the typical what am I doing wrong question but I have a Sigma 600mm mirror lens with a problem. The black paint on entire surface of the body is sticky. It feels like the paint is wet and if I hold the lens I leave finger prints in the paint, the lens functions properly. Has anyone encountered this problem and what can be done to fix it. All my lenses are in a dry climate controled place and non of the other lenses are having this problem.

If the lens is still in warranty I would send it in. If not, I have no clue.

maybe you did clean the lens barrel with some very aggressive liquid? sounds like the paint is not in the state it should be in.

Thanks forthe reply,

Sabbath999, It's not under warranty. The lens is probably 8 or 9 years old.

Alex, I haven't cleaned it since I've owned it.

All my other lenses are ok, it's just this lens and I do own another Sigma lens. I have written Sigma an email and I'll see what they say.

was there any pre-owner?

maybe it was heavily scratched and he painted it with an unsuitable paint before he sold it

Hey Alex there was a pre-owner but I think that the paint is original because all the markings are still on the lens.
