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

• Constant f/2.8 Aperture Throughout: The fast, unwavering f/2.8 maximum aperture ensures unmatched low-light performance across the entire focal range while creating a shallow depth of field that beautifully separates subjects from distracting backgrounds.

• Prime-Grade Optical Formula: Incorporates one Fluorite element, four Ultra-low Dispersion (UD) elements, and a molded glass Aspherical element. This premium arrangement dramatically suppresses chromatic and spherical aberrations, maintaining crisp detail and high contrast from corner to corner.

• Dual Nano USM Focus Drive: Driven by a sophisticated dual-focusing group system utilizing two independent Nano USM motors. Focus acquisition is virtually silent, instantaneous, and tracks moving subjects with pinpoint accuracy for both high-speed stills and cinema tracking.

• Up to 6 Stops of Coordinated IS: Offers up to 5.5 stops of built-in optical image stabilization. When paired with a compatible EOS R body featuring In-Body Image Stabilization (IBIS), the Coordinated IS elevates shake correction up to a staggering 6.0 stops.

• Extender Native Support: Fully compatible with the RF 1.4× and RF 2× teleconverters. It transforms seamlessly into a 140-420mm f/4 or a 200-600mm f/5.6 workhorse without sacrificing autofocus acquisition tracking speeds.
