Focal Length Comparison

Wide Range of Focal Length

See how the RF100-300mm f/2.8L IS USM’s wide range of focal length and telephoto compression can help you get that perfect shot.

Amazing Focus Capabilities

With two Nano USMs, the lens focuses very quickly and silently, making it suitable even for movie recording. When combined with the newly improved floating focus system, outstanding image quality is achieved throughout the focusing range.

Focus Breathing Correction The angle of view changes slightly during focus racking while recording video, causing an annoying 'pulsing' effect called focus breathing. The RF100-300mm f/2.8L IS USM supports the correction of this phenomenon when used with a compatible camera, ensuring a smooth and natural result consistently.

Beautiful Bokeh

Fluorite and UD lenses are effectively used to suppress all types of aberration in order to produce stunning bokeh. This, along with a large aperture of f/2.8 and nine aperture blades design, creates captivating pictures that bring the subject to life.

Air Sphere Coating (ASC) Suppresses ghosting and reduces flare from your images through the innovative use of an anti-reflection technology that forms an ultra-low-refractive index layer on the elements within the lens.	UD Lens This lens uses four single Ultra-Low Dispersion (UD) lens elements with low refraction and low dispersion, reducing axial and magnetic chromatic aberrations to deliver higher image quality.
Fluorite Fluorite lenses suppress chromatic aberration to deliver high quality images while contributing to the lightweight built.	Moulded Glass Aspheric Lens The moulded glass Aspheric Lens improves image clarity all the way to edge of the image.

Incredible Sharpness The RF100-300mm f/2.8L IS USM zoom lens uses cutting-edge optical design to maximize the EOS R system and RF mount's unique feature. Despite being a zoom lens, it achieves image quality that rivals fixed focal length L lenses across the entire image. When combined with an extender, the RF100-300mm f/2.8L IS USM achieves image quality comparable to super-telephoto L zoom lenses without an extender.

Close-up Often with a super-telephoto, it's hard to get a close-up shot, but the RF100-300mm f/2.8L IS USM has a short minimum focusing distance of 1.8 metres, which is uncommon for a lens of this range. Now you're able to get some close shots with a maximum magnification of 0.16x (at 300mm focal length). This frees you from creative restrain so you can focus on creating your vision.

Image Stabilisation Get tack-sharp images even when shooting handheld in low light. The lens provides up to 5.5 shutter speed stops of image stabilisation with the built-in Optical Image Stabiliser (Optical IS). When used with compatible cameras, the Coordinate Control IS that works with the In-Body IS will grant you up to 6 stops of stabilisation.	IS Modes IS Mode 1 for stationary subjects IS Mode 2 for panning shoots IS Mode 3 for subjects with unpredictable movement

Built for Professionals

Providing convenience for field experts was one of the guiding principles for the development of the RF lenses. On the lens, the buttons and switches are strategically placed so you can access them without ever taking your eyes off the camera. The tactile customisable control ring allows for quick exposure adjustments, while the focus and zoom rings are designed and positioned thoughtfully for ease of use.

Size Comparison

The RF100-300mm f/2.8L IS USM has certainly redefined the meaning of portability for large aperture super-telephoto zoom lenses.

Pairing it with the EOS R3 weighs approximately 3.612g but it is still lighter than the EF200-400mm f/4L IS USM Extender 1.4x lens, weighing 3,620g without a camera body.

Thermal Barrier Coating The signature Canon white thermal barrier coating is highly reflective and prevents overheating even in hot weather.	Drip, Dust & Shock Resistance The lens's mechanical structure is designed to make it very durable and resistant to vibrations and shocks while keeping dust and water droplets out.
Fluorine Coating Smudge-resistant fluorine coating on the front and back lens prevents moisture and oil from sticking. You can easily wipe off the oil with a dry cloth without using a solvent.	Tripod Mount The sturdy tripod mount provides stability when fixed to a tripod. The cushion on the mount adds comfort for prolong usage.
