Canon - RF100-500mm F4.5-7.1 L IS USM Telephoto Zoom Lens for EOS R-Series Cameras - White

Great reach, much lighter than my 150-600mm Sigma, fast autofocus, very sharp pictures. Only complaint is the Tripod collar doesn't completely lock down, it gives a little. A bit too pricey, also.

I’ve been very impressed with the Canon RF100-500mm F4.5-7.1 L IS USM. The image quality is excellent throughout the zoom range, and the autofocus is fast, quiet, and very accurate. Paired with an EOS R-series camera, it does a great job tracking moving subjects and has been especially good for wildlife and aviation photography. The 100-500mm range is extremely useful because it gives you enough flexibility to frame subjects that are relatively close while still having plenty of reach when they’re farther away. The image stabilization also works very well and makes handheld shooting much easier than I expected for a lens with this much reach. For an L-series telephoto zoom, it’s also very manageable to carry around. The build quality feels excellent, and the controls are easy to use. My only real downside is the price, but the performance and versatility make it worth it if you regularly shoot sports, wildlife, airshows, or other distant subjects. Overall, this has quickly become one of my favorite lenses and a great match for the Canon R5 Mark II.

Fantastic wildlife lens. Even handheld on an R5C without IBIS, the images are sharp at 500mm. I do wish it reached 600mm, but the 1.4x teleconverter works great, and with good lighting it still delivers super-sharp results. Fast autofocus, strong stabilization, and surprisingly lightweight. Excellent for bird photography.

The Canon RF 100-500mm F4.5-7.1 L IS USM lens is an absolute game-changer for wildlife and sports photography enthusiasts. Its build quality, hallmark of Canon’s L-series, is both durable and lightweight, making it perfect for photographers on the go. The lens extends its reach to an incredible 500mm while still maintaining sharpness and image clarity throughout the zoom range. The image stabilization (IS) on this lens is nothing short of spectacular. Even at the extreme telephoto range, handheld shots come out crisp and stable, thanks to its 5-stop IS system. Paired with a Canon EOS R series camera, the lens performs brilliantly, delivering fast autofocus and exceptional accuracy, making it a reliable tool for tracking fast-moving subjects like birds or athletes. Despite its relatively modest maximum aperture, this lens still provides beautiful background blur, creating stunning subject isolation. The zoom ring operates smoothly, and the lens’s overall ergonomics are spot-on, making long shoots more comfortable. Plus, its weather-sealing ensures peace of mind when shooting in unpredictable outdoor conditions. The Canon RF 100-500mm’s versatility, combined with its impressive optical performance, makes it one of the best telephoto zoom lenses on the market for anyone looking to capture action from a distance. Whether you're shooting wildlife, sports, or even distant landscapes, this lens is a must-have addition to your kit.

This lens is fantastic! Sharp images, great magnification and use cases are awesome! One of the things that i wanted to clear up with this review is what it "DOES" come with when purchased. Doesn't Seem like Canon nor Best buy have it clearly listed - so here it goes: 1) Lense RF 100-500mm F/4.5-7.1 L IS USM telephoto Lens 2) Lens Hood (ET-83F) 3) Tripod Mount (Yes it does include it) 4) Case 5) Strap. Case is actually pretty nice! Attached are some pictures of the Product along with a couple space photos i took with it tonight (1/12/2022). Keep in mind this is just using a Canon EOS R6 (My Nightime Camera) and this lens no tracking mount nor filters. You can see Orions Nebulae at 100mm or 500mm quite easily and if you run an Extender (Canon RF2x) then you can get 600 to 1000mm out of this lens which makes it even better in my honest opinion. Moon shot was take with an 2x Extender. Other space pictures were just the lens and no extender one at 100mm the other at 500mm, Both of the night time sky and Orion Nebulae. Overall very happy with the lens and it is proving to be quite versatile. The Simple things like having a sliding door on the hood to make adjusting a lens filter easier (Priceless)..
