Canon RF100-300mm F2.8 L is USM

Over the years, the Canon RF 100-300mm F 2.8 L IS USM Lens has emerged as a revolutionary tool for professional photographers and videographers, offering an exceptional zoom range and superior image quality. This lens is specifically designed for capturing stunning images with beautiful bokeh, making it an ideal choice for theater work, event photography, and indoor sports like swimming, gymnastics, and basketball. The lens boasts a high-performance constant f/ 2.8 maximum aperture, a feature that ensures excellent low-light performance, fast shutter speeds, and incredible bokeh across the entire zoom range.

The optical design of the Canon RF 100-300mm F 2.8 L IS USM Lens includes a fluorite lens, four UD (Ultra-low Dispersion) glass elements, a fluorine coating, and Canon's SSC (Super Spectra Coating) to minimize ghosting and flare, delivering excellent optical quality from edge to edge. For consistently sharp results, the lens features built-in optical Image Stabilization, offering up to 5.5 stops of shake correction. When paired with an EOS R-series camera with In Body Image Stabilization (IBIS), the Coordinated IS allows for up to 6 stops of correction, ensuring clearer detail in low-light situations without the need to increase the ISO or decrease the shutter speed.

The Canon RF 100-300mm F 2.8 L IS USM Lens is equipped with a dual Nano USM focusing system, providing incredible focus speed and accuracy throughout the entire focus range. This design also contributes to the balanced weight of the lens, reducing fatigue during handheld use. The lens incorporates a Control Ring on the lens barrel for direct setting changes, including shutter speed, aperture, and exposure compensation. This feature adds a third dial to the EOS R camera's main dial and quick control dial, enhancing user control and convenience. Despite its extensive features, the RF 100-300mm F 2.8 L IS USM lens weighs just under 6 lbs, making it the lightest f/ 2.8 300mm zoom lens on the market.

It also features a focus preset button near the back of the lens for easy reach, allowing you to pre-focus on a spot and immediately jump to the memorized position via the focus preset button. The lens is compatible with Extenders RF 1.4 x and RF2x, allowing you to expand the effective telephoto power to 140-420mm at f/4 with the Extender RF 1.4 x, or to 200-600mm at f/ 5.6 using the Extender RF2x. Built to L series lens specifications, the RF 100-300mm F 2.8 L IS USM features a dust and water-resistant design with seals around the mount, switches, and rings.

The lens also has a specially designed fluorine coating on its front surface to prevent water, oil, and other surface residue from sticking to the lens, facilitating quick and easy cleaning.
