Review Summary
2025-07-12T20:00:00
As a professional wildlife photographer with over three decades behind the lens, I've trusted Canon gear to perform in some of the most extreme and remote environments on Earth. From the sweeping savannas of Africa to the rugged peaks of the American West, Canon has never let me down. I purchased my first EF 800mm in 2016, and it became an essential part of my field kit. But over the past three years, I've transitioned all of my gear to Canon's mirrorless platform-and the results have exceeded every expectation. The new RF 800mm paired with the EOS R5 Mark II is nothing short of exceptional. The clarity, speed, and reliability of this combination are unmatched. It delivers stunning detail, even in low light, and the autofocus tracking is a game-changer for wildlife subjects that never sit still. My current core setup includes two R5 bodies (soon to be upgraded), the R5 Mark II, and Canon's finest L-series glass: the 24-70mm, 70-200mm, 100-500mm, and of course, the new RF 800mm. This lineup allows me to cover everything from intimate wide-angle landscapes to ultra-telephoto wildlife portraits-all with confidence and precision. Canon's innovation, support, and commitment to professional image-makers is why I've stayed with them throughout my career. The mirrorless platform has taken my work to new heights, and I look forward to what's next. Thank you, Canon, for continually raising the bar and delivering the tools that help me tell the wild stories that matter most. Thank you Canon!

I've been using this lens for almost a year now. This lens coupled with the R5 makes an exceptional lens for us Florida bird photographers. As with all the big L lenses (I also have the 600 f/4) the image quality is exceptional. The lighter weight makes it pretty easy to hand hold?but the best images come from the tripod. It's not going to be a lens for everyone, but if you're a serious bird photographer you'll love this one.

Light weight, sharp, and fun to shoot.

I've been using this lens for almost a year now. This lens coupled with the R5 makes an exceptional lens for us Florida bird photographers. As with all the big L lenses (I also have the 600 f/4) the image quality is exceptional. The lighter weight makes it pretty easy to hand hold?but the best images come from the tripod. It's not going to be a lens for everyone, but if you're a serious bird photographer you'll love this one.
It's the Canon RF 800mm f/5.6 L IS USM Lens, a high-quality, powerful, and reliable addition to the EOS R System, designed for professional and advanced photographers. This innovative lens is perfect for capturing wildlife, motorsports, and more, with its superior image quality and super-telephoto capabilities.
The lens features two large-diameter Fluorite elements, one Super UD (Ultra-low Dispersion), and one UD-glass element, all working together to provide outstanding correction of color fringing. This, combined with the Air Sphere Coating, ensures superb contrast and sharpness, delivering images that are sharp from center to corner, even at maximum aperture.
With an 800mm focal length, this lens enables you to achieve incredibly soft backgrounds and tremendous visual impact. The Optical Image Stabilization provides up to 4.5 stops of shake correction, ensuring consistent and sharp results, even in challenging conditions.
The RF 800mm f/5.6 L IS USM Lens is impressively light at 6.9 lbs., making it versatile and easy to handle. It's compatible with both RF1.4x and RF2x Extenders, allowing for even more reach at focal lengths of 1120mm and 1600mm.
The lens also features a customizable Electronic Focus Ring, with Manual Focus Capability during SERVO AF, and two focus presets that allow you to instantly return to one or two memorized focus distances. The 9-blade circular aperture ensures beautiful, soft backgrounds, adding depth and intensity to your photos and videos.
Constructed to the durable L-series specifications, the RF 800mm f/5.6 L IS USM Lens is dust and water-resistant, with a fluorine coating on the front element for easy cleaning. This lens is not just a tool, but a gateway to capturing the world in stunning detail.
