The Canon RF 75-300mm f/4-5.6 is a lens designed with one primary goal: making extreme telephoto reach accessible to absolutely everyone. If you have just purchased your first Canon EOS R-series mirrorless camera and want to experiment with capturing distant sports, backyard wildlife, or highly compressed portraits without spending hundreds (or thousands) of dollars, this is the most budget-friendly full-frame telephoto lens in the Canon lineup.
To achieve its incredibly low price point, Canon adapted the optical formula of their classic DSLR-era EF 75-300mm III directly to the modern RF mount. While it skips high-end features like optical stabilization and silent focusing, it provides a massive 4x zoom range that lets you pull distant subjects right into your frame. When mounted on an APS-C crop-sensor camera (like the EOS R50 or R10), it provides a staggering 120-480mm equivalent field of view.
Unbeatable Price: This is the defining feature of the lens. It opens the door to telephoto photography for beginners, students, and hobbyists who want to experiment with long focal lengths without committing to a major financial investment.
Classic Telephoto Reach: The 75-300mm focal range is incredibly versatile. It allows you to shoot flattering, tightly cropped portraits at the 75mm end, and then zoom all the way out to 300mm to capture daytime field sports or distant wildlife.
Relatively Fast Aperture: While it isn’t an f/2.8 professional lens, its f/4 to f/5.6 variable aperture is actually brighter at the telephoto end than many modern, more expensive RF super-zooms (which often drop to f/7.1 or f/8). This allows it to let in a bit more light for faster shutter speeds when shooting outdoors.
Super Spectra Coating: Canon has applied their Super Spectra coating to the glass elements to help suppress ghosting and flare, improving overall contrast and color accuracy when shooting in bright, sunlit conditions.
Lightweight Portability: Weighing just 1.12 lbs (507g), it is remarkably light for a full-frame 300mm lens. It won’t weigh down your camera bag, making it an easy companion for travel, zoo trips, and daytime hikes.
