  • Dedicated, programmable Control Ring, with click-stop operation.

One of the most exciting features of the Canon RF 100-300mm F2.8 L IS USM Lens is its impressive focal range, spanning from 100mm to 300mm, making it perfect for capturing distant subjects with ease. With nine circular aperture blades, the lens delivers stunning bokeh, making your subjects stand out against a beautifully blurred background. Additionally, the lens offers an incredible f/2.8 maximum aperture throughout the entire zoom range, delivering great low-light performance, incredible bokeh, and fast shutter speeds.

When paired with a Canon EOS camera R series camera, you can unlock the full potential of this lens, taking advantage of six stops of optical image stabilization to capture stunning shots even in low-light conditions. This lens is ideal for capturing action and sports photography, wildlife and nature photography, and stunning portraits.

The Canon RF 100-300mm F2.8 L IS USM Lens boasts Canon’s signature lightning-fast autofocus, thanks to two built-in nano ultra-sonic motors (USMs) that enable the lens to focus effortlessly from close-up to infinity. A focus preset button is also included, which allows you to focus on a predetermined distance where you expect the action to occur. This feature is particularly useful when photographing wildlife or sports.

The lens is designed to fill the gap left by the beloved EF 300mm f/2.8 L lens, and it certainly delivers on that front. While the price tag might seem high at first glance, it is important to note that the RF 100-300mm f/2.8 L is aimed squarely at the professional luxury market, and is therefore competitively priced compared to other similar high-end lenses. This lens is built exceptionally well, featuring one fluorite lens, four ultra-low dispersion (UD) glass elements, a fluorine coating, and a super spectra (SSC) coating to help minimize ghosting and flare. Seals around the mount, switches, and rings prevent dust and moisture from entering the lens, and a specially designed fluorine coating prevents grime from sticking to the exterior.

In line with other telephoto lenses in the RF series, the RF 100-300mm f/2.8 L has an impressive five-and-a-half stops of shake correction, which can be bumped up to six stops when paired with an in-body image-stabilized mirrorless body. This is a marked improvement over its predecessor, the EF 300mm f/2.8 L, which maxed out at four stops of stabilization.

The RF 100-300mm f/2.8 L also has a dedicated, programmable control ring on its barrel, which can be programmed to control anything from shutter speed to ISO. This feature is especially useful for quick adjustments on the fly.

Finally, those looking to enhance the focal length of this lens can use the Extender RF 1.4x and Extender RF 2x. These extenders can expand the effective focal length to 140-420mm at f/4 with the Extender RF 1.4x, or to 200-600mm at f/5.6 with the Extender RF 2x.

Roberto Valenzuela, fashion and wedding photographer

For decades, the 300mm f/2.8 telephoto lens has been an industry standard for photojournalists, professionals, and aspiring enthusiast photographers due to its outstanding image quality, excellent speed for indoor shooting, and relatively light weight for hand-holding. Now, with the launch of the RF100-300mm F2.8 L IS USM, Canon delivers the flexibility of a zoom lens design with the truly outstanding quality of a 300mm f/2.8 L-series telephoto lens. Exceeding the reach and potential of traditional 70-200mm lenses, and adding zoom flexibility to its Canon EF 300mm f/2.8L IS predecessor, the RF100-300mm F2.8 L IS USM lens brings new value to customers with the following features:

  • Weather and Dust Resistant — Durable in various environmental conditions
  • Compact and Lightweight Design — Despite capabilities to zoom over 300mm, this lens is unusually lightweight, just barely heavier than the EF300mm f/2.8L IS II

“I love this lens! It’s incredibly lightweight, versatile, and sharp. Toss on the 2x extender and you can snipe gorgeous frames at a distance, especially with the built in image stabilizer. This lens is going to change the game for live concerts, weddings, and so much more.”

Ben Hagarty, Grammy award-winning cinematographer

This telephoto zoom lens is ideal for professionals who use a Canon EOS R3, EOS R5 or EOS R6 Mark II full-frame mirrorless camera, but can also be a catalyst for users who have developed into serious, aspirational enthusiasts and are looking to step beyond their traditional telephoto lens experience. Best use cases include, but are not limited to, indoor sports, motorsports, outdoor fashion, video and cinema, photojournalism and theater work.
