The dedicated Vello ET-101 Lens Hood is specifically designed for use with Canon's RF 800mm f/11 IS STM lens. It is primarily used to prevent unwanted stray light from entering the lens by extending and shading the end of it. A dedicated hood is crafted to perfectly suit the specific focal length of the lens it is designed for. Additionally, this hood features a non-glare matte finish on the interior surface to further prevent or limit lens flare. Also, since the end of the lens is extended, you get the added benefit of some extra protection from accidental impact.

The bayonet mount is designed to also work in the reversed position, allowing the hood to be placed backwards over the lens for a more compact storage solution.

Related Questions and Answers

Q: 1. Will this attach to my Canon 100mm f/2.8 macro lens?

A: No, it will not. The Vello ET-65 III Lens Hood is not compatible for use with the Canon 100mm F/2.8L EF IS USM Macro Lens; it is only compatible with the Canon 100mm f/2 EF USM lens, the Canon 85mm f/1.8mm EF USM lens, the Canon 135mm f/2.8 EF with Softfocus lens, and the Canon 100-300mm f/4.5-5.6 EF USM lens. If you are looking for the correct Vello lens hood for use on the 100mm f/2.8L EF IS USM Macro lens, the Vello ET-73 Dedicated Lens Hood, B&H # VELHCET73, would instead be the right option for your needs.

Q: 3. Will this fit the Canon EF 70-200mm f/2.8 L IS II?

Q: 4. Is this compatible with a Canon T5

Q: 7. will this fit my eos rebel t5 ?

A: The ET-65III lens hood fits the Canon 80mm f1.8, 100mm f2, 135mm f2.8 Soft Focus and 100-300mm f4.5-6.5 USM lenses. If you have one of those lenses attached to your Rebel T5 body, it will fit the lens. You need to identify the LENS you are trying to attach the hood to, not the camera body, for a good answer.
