The Canon RF 100-300mm F2.8 is a new version of the legendary EF 300mm F2.8. Canon didn't just make a new bayonet version of the old lens, but the structure and idea are now new. Instead of a fixed focal length, they have achieved a 100-300mm zoom in the same size class without sacrificing the brightness!

• A solid professional tool for nature and sports photography
• Fixed F2.8 aperture across the entire focal length range
• 5.5 aperture value stabilizer and with the body stabilizer, a total power of 6 apertures
• First-ever Dual Nano USM focusing motor
• Weather-protected construction and 112mm filter thread
• Works seamlessly with RF 1.4X and 2X teleconverters
• Closest focusing distance 1.8m

Ultra-fast autofocus and compatible with teleconverters

The 100-300mm focal length allows for quick response to shooting situations and the high aperture makes it great for shooting concerts and indoor sports, for example. The lens is compatible with the RF series teleconverters:

• Canon RF 1.4X teleconverter equivalent: 140-420mm F4
• Equivalent to Canon RF 2X teleconverter: 200-600mm F5.6

The Canon RF 100-300mm F2.8 L IS USM uses a Dual Nano USM system, in which two separate Nano USM focus motors independently control two different groups of lens elements. This floating structure ensures exceptionally fast autofocus and image quality remains extremely sharp at all focal lengths and focusing distances.

The focusing elements are located behind the tripod collar next to the bayonet, meaning the focus remains the same even when shooting handheld.

Professional-level usability

There is a Focus Preset button on the back of the lens, which can also be used with the right hand. This button can be programmed, for example, to a specific focus distance and the camera can be activated to focus at this point by pressing the button. The button can also be used as a programmable L-Fn button with a switch, which can be used to adjust different camera settings or focus modes. There are more of these Lens function buttons around the front of the lens.

In addition, like RF lenses, there is a programmable control ring for adjusting aperture or exposure compensation, for example.

The Canon 100-300mm F2.8 includes a 5.5-stop effective image stabilizer, which also works together with the EOS R cameras' in-body stabilizer, for a combined effect of 6 stops. The stabilizer's power and fast response are enabled by the new RF mount, while in EF series lenses such as the EF 300MM F2.8L II the maximum was four stops.

The lens is made in Japan.
