Canon announced on 20th April 2023, the new New Canon RF100-300mm f/2.8L IS USM – Versatile Telephoto Lens. This new telephoto zoom lens is a class-leading professional telephoto zoom lens for the RF mount. This is also Canon’s first-ever f/2.8 constant aperture zoom lens to cover the 100mm to 300mm focal length range. The new lens offers an unprecedented lightweight and versatile solution for sports, wildlife and also for photographers who require an extra reach while shooting at faster shutter speeds.

The RF100-300mm f/2.8L IS USM lens is based and innovated upon the EF300mm f/2.8L, a classic Canon telephoto lens for sports and action photography, that is renowned for its technology and excellent optical quality.

“With the new EOS R and RF lens ecosystem, Canon continues to push the boundaries of what’s possible in photography. The RF100-300mm f/2.8L IS USM is a testament to this – delivering superlative optical quality with its fast constant aperture and a useful range of focal lengths. As a game-changer for photographers who demand speed, flexibility, and versatility, the RF100-300mm f/2.8L IS USM empowers them to capture decisive moments with unparalleled precision and clarity.” said Edwin Teoh, Head of Marketing, Singapore Operations, Canon Singapore.

Constant Aperture f/2.8: Freeze action decisively from wide to close-up

The RF100-300mm f/2.8L IS USM’s constant aperture design allows users to utilise the large f/2.8 maximum aperture throughout the entire zoom range, even at the 300mm tele end. With this, users can freeze decisive moments at faster shutter speeds, which gives them a better chance of getting their desired shots. 

The distinctive, extremely creamy bokeh achieved through telephoto shooting at f/2.8 makes the RF100-300mm f/2.8L IS USM useful for creative expression even in genres such as portraiture, fashion, and weddings.

Zoom convenience: Multiple lenses in one lightweight body

The RF100-300mm f/2.8L IS USM’s 100mm to 300mm zoom capability (160mm to 480mm on an APS-C camera) covers the range that typically requires at least two or three lenses to achieve (Combinations previously required to achieve 100-300mm at aperture f/2.8: 70-200mm f/2.8 lens + 300mm f/2.8 prime lens, or 100mm + 135mm + 300mm prime lenses). Users can now conveniently zoom to track and keep dynamic subjects, such as soccer ball or birds in flight within the frame, even in locations with restricted mobility. It also means less gear to carry.

Extender compatibility: Reach up to 960mm f/5.6

For occasions that require greater reach, simply attach one of the compact, lightweight RF extenders. With Extender RF2x, you can zoom up to 600mm (full-frame camera) or a whopping 960mm full-frame equivalent (APS-C camera/APS-C crop mode) while maintaining a maximum aperture of at least f/5.6!

Fast Focusing, Optical Excellence

Driven by precise dual Nano USMs, AF is quick and accurate, complementing deep learning-based subject detection and tracking on cameras like the EOS R3. An innovative new electronic floating focus control system improves image quality while reducing weight, enhancing the signature RF mount L-series optical quality. This would enable sharp shots of swift action, right down to every sweat drop or feather detail.

The lens supports focus breathing correction during video shooting, delivering professional-looking footage straight out of the camera.

Other Notable Features
