==================================
The Dust Donut is a weather sealing rubber accesory that attaches to the mounting surface of your DSLR's lens and blocks dirt and moisture from collecting around your lens and camera's connecting area. This prevents harmful dirt and moisture from entering your camera body's opening and collecting on the digital sensor causing serious damage and image degradation.
The Problem:
- Nearly 75% of lenses available on the Canon EF lens mount lack any form of weather sealing
- All users whether professional, amateur, or anywhere in between are vulnerable to dust and moisture entering their camera's sensor cavity and lens optics during use regardless of the operating environment
- There currently is no way for a photographer to add weather sealing of any kind to the mount of their lenses without the use of bulky and cumbersome rain covers
- Interchangeable lens cameras require frequent and time consuming sensor cleaning due to dust build up
- Dust particles can also penetrate the lens and collect between its optics and cause resolution loss and negatively effect the resale value of the lens
- Moisture can easily pass through an unsealed lens mount and condense on the optics causing haze and the growth of fungus
