Dedicated lens hood for RF 100-300mm f/2.8 L IS USM

The Canon ET-124 is a dedicated lens hood designed exclusively for the RF 100-300mm f/2.8 L IS USM lens. It blocks stray sunlight and other light sources to prevent glare and lens flare. The accessory also shields the front element from scratches, dust and impact. It is built for photographers and videographers who demand consistent optical performance.

Replaces lost or damaged original hood for same lens

This hood replaces a lost, cracked or misplaced original hood for the RF 100-300mm f/2.8 L IS USM. The upgrade is worth it whenever flare reduces contrast or the front glass is exposed to handling risk. A secure, model-specific fit ensures the petal shape aligns with the zoom range without vignetting. No generic alternative matches the precise geometry.

Suits owners of the RF 100-300mm f/2.8 L IS USM

The ET-124 suits owners of the RF 100-300mm f/2.8 L IS USM who shoot in bright or backlit conditions and want maximum flare control. It is not for users of any other RF or EF lens, as the mount and petal profile are unique to this model. Buyers needing a hood for a different focal length or filter diameter should look elsewhere.

Questions about this item

What filter thread or diameter does the ET-124 hood fit on the RF 100-300mm f/2.8 L IS USM lens?

The ET-124 hood is designed specifically for the Canon RF 100-300mm f/2.8 L IS USM lens and attaches directly to its front mount without needing a separate filter thread size.

How do I attach the ET-124 hood to the RF 100-300mm f/2.8 L IS USM lens, and what is the common mistake to avoid?

Align the hood's mounting index with the red dot on the lens barrel, then rotate clockwise until it clicks; the step often missed is ensuring the click confirms a secure lock.

Will the ET-124 hood's mounting mechanism or finish wear out and need replacement over time?

The hood is built from durable materials to protect the lens from scratches and dust; under normal use the bayonet mount and finish do not require scheduled replacement.
