Hi all,

I love my SL2s and the lenses with it but was just wondering if anyone else is experiencing the rubber rings turning whitish? I look after my gear well and they live in a dehumidifeid cabinet when not in use. 

Any recommendations on how to treat/prevent this??

 

Thanks in advance!

why don't you post a photo so people can see what happened exactly?

Small poll, I know, but both these examples involve dehumidifier cabinets.

Thanks for sharing! I'll give the old toothbrush and water solution a go, cheers!

Good idea. I'll post a pic when I get time but it basically looks like that 90mm in the example above!

Rub it off with a wet cloth (water + 3% glycerol). This was successful with my Hasselblad/Zeiss lenses.

This happens to a few of my lenses but not all equally used lenses. Not sure why. I keep a dry toothbrush ready just for this. I just give the rubber-like focus ring a brisk dry brush a couple of times over and that does the trick, I finish with a rocket blower just incase there is any dry residue left after the brushing. I don't use any type of liquid, alcohol or any solution. 

From what I have experienced, once it starts on one lens it seems to happen again on the same lens from time to time--must be some breakdown in the material.. But the toothbrush alone seems to be the solution.

Thanks for your suggestion! Will try this first before the solution method. Haven't had a chance to try anything yet but hopefully soon. 👌

I believe that the white is salt deposit from moisture in handlers hands / fingers.

Yes this happened also to my 75mm Summarit-M - a careful few minutes with a barely damp old toothbrush seemed to solve it, though it's never going to look as black as the (metal) aperture ring just above it.
