    Canon’s New RF100-300mm f/2.8L IS USM: Unprecedented Telephoto Versatility

    Get the best of both worlds by capturing fast and far with the 100 to 300 mm zoom range, while maintaining a constant aperture of f/2.8 for smooth bokeh

    HO CHI MINH CITY, 20 April 2023 — Canon today announced the RF100-300mm f/2.8L IS USM, a class-leading professional telephoto zoom lens for the RF mount. As Canon’s first-ever f/2.8 constant aperture zoom lens to cover the 100 to 300 mm range, the new lens offers an unprecedented lightweight and versatile solution for sports, wildlife, and photographers who require extra reach while shooting at faster shutter speeds. The RF100-300mm f/2.8L IS USM innovates upon the EF300mm f/2.8L, a sports and action photography classic lens renowned for its technology and excellent optical quality.

    “Based on feedback from photographers and leveraging on our accumulated knowledge and experience, we engineered a lightweight, constant aperture zoom lens that is future-proofed for the next generation of mirrorless cameras,” said Imasaka Daido, Director of Regional ICB Sales & Marketing, Canon Singapore.

    “Dựa trên phản hồi từ nhiếp ảnh gia và nhờ kiến thức cũng như kinh nghiệm đã được tích lũy bấy lâu, chúng tôi tạo ra chiếc ống kính zoom khẩu độ cố định, nhẹ, hiện đại dành cho thế hệ máy ảnh không gương lật tiếp theo," ông Imasaka Daido, Giám đốc Bộ phận Kinh doanh & Tiếp thị ICB của Canon Singapore cho biết.

    The Speed and Flexibility to Capture Decisive Moments

    f/2.8 constant aperture: 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 300 mm 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 100 mm to 300 mm zoom capability (160 mm to 480 mm on an APS-C camera) covers the range that typically requires at least two or three lenses to achieve (Combinations previously required to achieve 100-300 mm 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 960 mm 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 600 mm (full-frame camera) or a whopping 960 mm full-frame equivalent (APS-C camera/APS-C crop mode) while maintaining a maximum aperture of at least f/5.6!

    The Lightest 300mm F/2.8 Constant Aperture Zoom Lens for Full-Frame Cameras on the Market [1]

    The RF100-300mm f/2.8L IS USM + EOS R3 combination is lighter than the EF200-400mm f/4L IS USM Extender 1.4x alone, weight over 1 kg less. It also offers substantial mobility savings than the EF300mm f/2.8L IS II USM + EOS-1D X Mark III while offering 3x zoom functionality.

    Lens Camera Total Weight
    RF100-300mm f/2.8L IS USM (Approx. 2,590 g)

    EOS R3 (Approx. 1,022 g)

    Approx. 3,612 g [2]

    EF300mm f/2.8L IS II USM (Approx. 2,360 g) EOS-1D X Mark III (Approx. 1,448 g) Approx. 3,798 g [3]
    EF200-400mm f/4L IS USM Extender 1.4x (Approx. 3,620 g) Nil Lens only: Approx. 3,620 g

    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.
