Canon RF 100-300mm f/2.8 L IS USM Lens

The Canon RF 100-300mm F2.8 L IS USM pairs the reach and speed of a classic 300mm f/2.8 prime with the flexibility of a zoom. It's built for photographers covering indoor sports, events, theater, and fashion, where subjects move unpredictably and a fixed focal length isn't practical. A constant f/2.8 aperture across the zoom range keeps it usable in low light while still isolating subjects from busy backgrounds.

• Constant f/2.8 zoom: Keeps a bright, constant f/2.8 aperture from 100-300mm for low-light work and shallow depth of field.
• Dual Nano USM autofocus: Combines ring-type USM and STM focusing motors for fast, near-silent autofocus in photo and video.
• Up to 6 stops of stabilization: Optical IS delivers 5.5 stops alone, or up to 6 stops of Coordinated IS when paired with an in-body stabilized EOS R body.
• Focus range limiter: Switch between full range or a 19.7 ft-to-infinity range for faster focusing on distant subjects.
• Weather-sealed L-series build: Sealed construction and a front fluorine coating guard against dust, moisture, and smudges.
• Lightweight for its class: Weighs 5.8 lb and measures 12.7 in, notably manageable for an f/2.8 telephoto zoom.
• Focus preset button: Store a focus distance and instantly return to it, or reassign the button as a secondary L-Fn control.
• RF extender compatible: Works with the optional RF 1.4x and 2x teleconverters for extended reach.
