I’ve got a lot of Canon gear, but only one L-series lens of my very own, and that’s also the only one that features a rubber gasket where the lens mounts to the body to keep out dust and moisture. It’s a shame that it isn’t included in any other lenses (including some pricey Sigma glass I own), because it’s a relatively inexpensive component and one that can really help prolong the life of your body and lens. That’s why a new Kickstarter project called Dust Donut is such a great idea.
The project, from Joshua Tree, Calif.-based photographer Tyler Sterbentz, adds basic weather sealing to any Canon EF Mount lens (including third-party offerings from Sigma, Tamron and the like) starting at just $20 for a single unit pre-order pledge. That covers about 75 percent of the lenses available from Canon itself for EF-mount bodies, according to Sterbentz, and gets rid of the need for photographers to use lens covers and skins to achieve the same effect.
