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.

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

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.
