DIY: Weather sealing a DA

I'm thinking that it should be possible to add a rubber gasket on the lens mount for weather proofing. This is what the WR's seem to have -- a nice red rubber gasket. Wonder where you can find one off that size?

I'm curious where I can find o-rings and rubber gaskets for a custom size of 57mm.

thanks........

A gasket, no matter how thin, will probably affect infinity focusing.

Someone needs to pull apart a DA50-200mm just to settle this. Mmmm...maybe it will be me. I am not too pleased with this gift lens so far. More testing tonight.

What do you guys think of this method:

A wide rubber band seems to do a decent job around the mount.

The question has to be asked. How do you plan to test any DIY weather sealing you might come up with?

This post made me lol a bit. :-)

The krytox grease thing seems sketchy to me but the rubber band does seem like a rather good, logical idea. If the fit is tight and there are no gaps then it should, in theory, do a decent job of keeping water from entering the lensmount (which has happened to me before with cheaper lenses). Now, Damn Brit raises a fine point about testing being required to declare that theory an actual sound practice, but I don't think any testing is required if it's more of a "just in case" to increase one's peace of mind.

Water can, of course, enter other sections of the lens.
