Customer Ratings & Reviews

Excellent lens. Not many alternatives available from Canon at this price.

Best lens for birding and landscape! A bit heavy, but well worth it. Unbelievable reach, especially when coupled with an extender.

This lens is amazing for photographing college football, I have been able to reach the other side of the field and get crystal clear photos I am using this lens with the canon r6 body

Exceptional optics. As a landscape and nature photographer, this lens has a wide range of uses and keeps proving itself more useful.

I never expected this lenses would be so amazing in the quality of the picture and the easy way to capture the image. I recommend a 100% to buying

The lense is a great to get and use. Great range and very clear.

Exactly what I was looking for for sports photography!!

I have never had a lens over 250 mm zoom before, so I love having the ability to bring things in closer. I wish it was a little lighter, but it seems all quality lenses are heavy. Overall, though, I love it.

Was shooting with the EF 600mm is L Series lens and at about 30lbs it was as beast in a backpack... This baby is about 3lbs and is a run and gun superstar.

The reach is out of this world with this amazing lens.

Excellent Canon lens. We used it during our recent Yellowstone National Park visit. The images from it are sharp. Amazing stabilization. I used it for some short video clips hand-held.

Excellent lens with outstandng image quality. The lens is well built and hefty. A tripid/monopod mount is provided and is removable.

Great lens. Easy to use. Best quality lens you can buy for sure.

This is an excellent versatile lens and purchasing it from Best Buy was a positive experience.

Excellent lens, used on Safari in Africa, was great for this purpose!

Brilliant lens! Much preferred to the 500/5.6 it replaced.

Excellent lens! Would highly recommend it for anyone with an RF Mount camera.

Good lens overall. Been using the lens for about two weeks now primarily for shooting wildlife. Works well as long as there is a reasonable amount of light. Not good for taking pics at dusk when fully extended but that’s not surprising……Also tough to pack if you add the 1.4 extender.

Outstanding quality. The lens is lighter than the original 100-400 and gives you extra lenght.

This is a great lens. The eye/face detection is amazing. I use this lens for nature, mainly bird and butterfly pictures. The auto focus tracking is out of this world :) Took me a minute to figure out if you just wait (less than a second it locks on to the eye) the you hold auto focus and it tracks it.
