Imagine you have been planning an epic street shoot for weeks with your photography buddies, but on the day of the shoot, you look out your window and realize that it’s drizzling. For most photographers, this would kill all their plans for shooting that day, but luckily for you, you have a weather-sealed dslr, such as the Canon 5D Mark III. However, you discover that most of your lenses are not weather-sealed.
In fact, nearly 75% of lenses available on the Canon EF lens mount lack any form of weather sealing.
To address this common and frustrating problem, Tyler Sterbentz created the Dust Donut, a weather sealing rubber o-ring that attaches to the mounting surface of a DSLR’s lens.
By blocking dirt and moisture from collecting around your lens and camera’s connecting area, the Dust Donut prevents harmful dirt and moisture from entering your camera body’s opening and collecting on the digital sensor causing serious damage and image degradation.

Lens Compatibility List
Because they are created to add a weather resistant seal in the same way that some of the high end Canon “L” series lenses do, Dust Donuts are precisely engineered to fit exactly on your lens mount. With no sloppy over hangs or gaps to worry about that could allow leaks or cause lens attachment problems, you can freely shoot and change lenses with peace of mind.
