Customer Ratings & Reviews

I use this lens to shoot sports. Specifically pro baseball snd hockey. The focus is super fast and the lens isnt nearly as heavy as similar lenses made by other manufacturers. Big fan of this lens, would highly recommend!

This is a beautiful lens. It is lightweight and easy to carry and use. It takes sharp beautiful pictures. I use the lens almost exclusively to capture birds in -flight, and most of the time the birds are not close. I have the old Canon 400mm f5.6 lens which is extraordinarily sharp, but this new lens does virtually as well.

Performance is incredible, as it is fast, sharp, and when mated with my R6, only came off my camera for the occasional landscape shot as I was there for wildlife...and the area did not disappoint. Yes it is expensive, however buy this before getting the 70-200 and then think about all the times you missed a shot because you had this lens vs. the 70-200. At this point, I am reducing what I carry because of this lens.

Bought this Len on line for outdoor sports and wildlife photography. It is very versatile and gives me wonderfully sharp images. As always Best Buy is a great source for professional photographers and for folks who want high quality equipment

Love it! Beautiful lens, I haven’t made a zoo or wildlife trip yet but it has been exactly what I hoped for. Very heavy for me but it’s to be expected… perhaps I will get a tripod I am a pet photographer for myself and other breeders And I had the chance to do a few photo sessions with it and it’s everything I hoped it would be, every whisker and every hair. You won’t be disappointed

This is a truly fantastic lens. I used it in Alaska photographing wildlife of various kinds, and it never let me down. I was able to get almost every shot I wanted, even from boats. The optical stabilization is stellar and despite the fairly narrow aperture, using auto ISO enabled me to get a great range of shots that I otherwise wouldn't have been able to get. It is a bit heavy, but not so much that it becomes too burdensome to carry, and having it at hand to get the shots I wanted was well worth the weight in my pack or in my hand.

Now i just let a review on the rf 100-400 basicallt saying u dont need to get this lens because the 100-400 was good enough..........but.........once i used this lens it blew me away.........on my canon eos r6ii the results is crazy..........if u have the money and can afford it i definitely recommend............

So I initially purchased this lens weeks ago but that particular lens ended up having a manufacturer defect. No fault of Bestybuy. Kuddos to Bestbuy for a smooth return process. Even more kuddos to Bestbuy for having had this in stock! When other sellers have been backordered for months. Keep checking the bestbuy site as they randomly get stock. I lucked out & got the only one they received. This is an amazingly build & designed lens as you would expect from a Canon L lens. It’s super sharp at all of the lengths & focus is fast! This is one of if not my favorite RF lens next to the 70-200mm RF. I highly recommend this lens if you need that extra reach! & also recommend getting the RF 1.4X Extender with this! No loss in quality & gives you about 200mm more reach!

Steadily rebuilding a Canon system after years of swearing by Nikon. The return policy of my local BBuyhas given me a great opportunity to “try things on” and this fantastic lens was the last step. Easy and always helpful. Very grateful for Best Buy!

The lens RF 100-500 is fantastic. With 500mm it can reach enough far enough to shot wildlife/birds with good quality. On the other hand it is not so heavy and bulky as other super telelephoto lenses. Very happy with the new toy.

If you are a Canon shooter and shoot wild life, ye have the legendary EF 100-400mm Now when you switch to mirrorless R bodies, while you sure can use the EF with adapter, but it makes more sense to get this bit lighter and addition 100mm reach lens that you can mount directly on the R body. Excellent focussing and superb image quality. Not sure now but at the time I purchased it, the availability was a great issue. So grab one when you see it. You will not regret.

I am an amateur photographer at best. My favorite subjects are animals. I especially like shooting birds in flight. This lens is fast and accurate. I paired it with a Canon R6 mirrorless camera and couldn't be happier. This combo doesn't miss focus that often and I keep more photos than ever before. I thought the cost was high until I started using it. I don't delete anywhere near as many photos as I used to. Worth the money for sure!

Amazing lens, its portable, light weight and can give your camera the reach (even at full frame) to catch that wildlife without scaring them away. This lens is also great for airshows, landscape photography and anything your imagination throws at it. Highly recommended.

Paired with R6 II, super sharp, fast focus, 4.5-7.1 aperture is just fine, good stabilization. Loved taking it to Alaska, glad I had the full range from 100-500. It was the only lens I used, and only once did I wish for wide angle.

It's definitely a great choice! I've heard a lot about it from wildlife photographers so i purchased it and even though I am a beginner I did amazing pictures! Comes in a nice transportation sturdy box.

Great lens at a great price. Sharp at 500mm as well as 100mm. I mainly do motorsports and zoo photography and this lens is great for both. It's light weight which makes it's easy to carry.

Had to wait awhile until my Canon EOS R5 came in from Best Buy. Once I paired it up to my new camera - I was more than pleased. This lens is hardy, sharp, and has a great focusing and zoom range. Canon has created a winner. I just wish it had a bit better aperture. 7.1 is a bit slow.

Purchased for sports photography and some wildlife. This lens really produced excellent photos. Was able to zoom in really close and get the most amazing shots. I would definitely love to check out other telephoto lenses from Canon at 800mm and up after seeing how amazing photos with this lens turned out.

Very SHARP lens, easy to carry and store in your bag

Canon L lenses are more expensive than 3rd party lenses, but can be worth it. The way it works with a Canon back of similar quality is very nice. You just need to decide if the Canon integration is with the premium, but for my use it was.
