Canon RF 100-300mm f/2.8 L IS USM Professional Telephoto Zoom

The Canon RF 100-300mm f/2.8 L IS USM represents the pinnacle of telephoto zoom engineering for the EOS R mirrorless system. Combining a fast constant f/2.8 aperture with a versatile focal range, this lens serves as a high-performance alternative to traditional 300mm prime optics. The sophisticated optical construction utilizes fluorite elements, ultra-low dispersion glass, and aspherical elements to ensure edge-to-edge sharpness and clarity. Advanced Air Sphere and Super Spectra coatings effectively eliminate ghosting and flare, even when shooting in challenging backlit environments. A Dual Nano USM autofocus system provides near-silent, lightning-fast focusing performance suitable for both high-speed sports photography and cinematic video. Integrated optical image stabilization offers up to 5.5 stops of shake correction, increasing to 6 stops when paired with stabilized EOS R bodies. The internal zoom and focusing mechanism maintains a constant lens length, providing superior balance and enhanced weather resistance for field use. Professional handling is augmented by four programmable Lens Function buttons and a customizable control ring for tactile exposure adjustments. This L-series optic features a robust, weather-sealed design and a fluorine front coating to withstand the rigors of professional assignments. Its compatibility with RF extenders allows for a reach of up to 600mm while maintaining exceptional image quality and autofocus precision.
