Canon RF 100-400mm f/5.6-8 IS USM Telephoto Zoom Lens with Control Ring for Canon EOS R Cameras

The Canon RF 100-400mm is an outstanding value - lightweight, surprisingly sharp, and a telephoto zoom that performs far beyond what its modest price suggests. I use it on my Canon R7, whose APS-C sensor effectively extends the field of view to the equivalent of 160-640mm. The crop sensor also uses only the sharp central portion of the lens, resulting in excellent image quality across the frame. While the maximum aperture of f/5.6-8 may seem limiting on paper, it has never been an issue for the way I use this lens. My telephoto photography is almost exclusively outdoors in good light, where the smaller aperture is easily offset by the R7's excellent autofocus and image stabilization. For wildlife, landscapes, and distant subjects, this lens delivers exceptional performance without the size, weight, or cost of Canon's premium telephoto lenses. I highly recommend it to anyone looking for an affordable, lightweight telephoto that consistently exceeds expectations.

have had for 2 years, tested this against the 100-500 and the images were the same quality. liked the 22oz vs 36oz, smaller and faster to use.

It works perfectly with our R8 and, as expected, is much better than the EF-S 55 - 250mm on our EF cameras. We may want to try the RF 800mm later.

Good lenses for travel wildlife and sports photography

I am getting great results with and without the 2x extender. The lens is light enough for off-hand shooting, but go with support for that big reach. I like that I can get full throw from 100 to 400 with just a quarter turn of the barrel to get that perfect frame without mucking my focus or aim.

Purchased this a week ago and love it - great lens for those animal photos

A very good lens, especially for its pretty inexpensive, light weight, focus is fast. But oh that f/11 @400mm is so slow! I don't know if I can get 'use' to having to really turn up the ISO to get fast enough shutter to freeze motion of animals and birds. I almost gave it 3 stars.

This is a great lens for the price. Light weight, compact, great for walking around. I used it with my Canon RP body, which was a nice all around set up. The quality of images, however, is not as good as my L series lenses, especially at the 400mm range. I returned the lens and opted for the 100-500mm.

The best lens you can have is the one you have with you when you want to take a picture! Because of the compact size and low weight of this lens, you are likely to have it along on your nature hikes and adventures. Of course it would be worthless if it did not perform optically/photographically - have no fear, it performs very well! Very quick and silent auto focus, smooth zoom, and efficient vibration reduction. It has become my got to lens, or better said, my "take with" lens!

This is a very flexible lens, with a decent focus speed and reasonably quiet. It's a touch on the slow side, but for the cost involved that's to be expected. Image quality is very good, takes full advantage of the R5 45MP sensor. It's nice to have the control ring on these new RF lenses!
