It's always the simplest inventions that leave you banging your head on the wall wondering why you didn't think of it first. This is especially true in the case of the Dust Donut—a simple product that leaves photographers wondering why something like this hasn't been done before. The Dust Donut is a simple, high-quality o-ring seal currently in the process of being produced via Kickstarter that aims to replicate the body to lens weather-sealing found in more high-end lenses such as Canon's revered "L" series. For explorers that are constantly out in the elements without weather-sealed lenses, it's common for dust and moisture to penetrate into the body and contaminate your sensor.
Currently the Kickstarter pitch is funded, with backers providing nearly five-times the amount requested. Dust Donut will be starting with Canon's EF series of lenses, of which 75% lack weather-sealing, with plans to develop products for Nikon, Olympus, and Sony.
You'll never get the great shots if you're afraid to use your equipment. The Dust Donut helps to make you a little bit more confident when it comes time to pull out your precious investment during bad weather.
