Canon RF 600mm f/4 L IS USM Lens

The Canon RF 600mm F4 L IS USM is Canon's flagship 600mm super-telephoto for EOS R-series bodies, built for wildlife, birds-in-flight, and motorsports photographers who need maximum reach at a wide f/4 aperture. It carries the same optical design as the EF 600mm f/4L IS III USM, so it delivers the image quality Canon's L-series 600mm lenses are known for, in a notably lighter package than earlier generations. It's suited to photographers who need to move fast with a long lens, not just leave it planted on a tripod.

• EF-grade optics: The same optical formula as the EF 600mm f/4L IS III USM delivers its established sharpness, contrast, and color at maximum aperture.
• 5.5 stops of stabilization: Three IS modes cover handheld shooting, panning, and shutter-triggered correction.
• Built for mobility: A significant weight reduction versus earlier 600mm f/4L designs makes it practical to carry into the field, not just mount and leave.
• RF extender compatible: Pairs with the RF 1.4x and 2x Extenders for 840mm at f/5.6 or 1200mm at f/8.
• Customizable manual focus: A three-speed electronic focus ring stays adjustable even while Servo AF is engaged.
• Two focus presets: Memorize two focus distances and instantly recall either via the playback ring, useful for fixed-position action.
• Weather-sealed L-series build: Dust- and water-resistant sealing plus a fluorine front coating that wipes clean without solvents.
