Canon RF100-400mm F5.6-8 is USM

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.

Excellent low noise camera (an R6), sharpness and light weight long lens. LCD and viewfinder are OK, but could be a bit sharper. Fairly accurate lens tracking on moving subjects. Fast autofocus. OK build quality for a light weight package. Interface is a bit overwhelming but very powerful once mastered.

Compared to my 200mm and 400mm zoom lenses that I've used with my Canon 5D Mark IV, this RF Lens is appreciated light weight. I've added a 2X magnified but I'm still OK with the weight and have been taking great photos with this lens on my EOS RP mirrorless camera (lighter than my 5D) without a tripod. All around, a very good experience.using a tripod.

This is my favorite telephoto lens hands down. It represents fantastic value for camera lenses. I use this lens most often during the early evening or during the day. At periods around sunset you'll find that ISO needs to be increased. The 'slow' F-stop is usually a non-issue. Given the light weight of the lens and long zoom, it has become one of my favorites.

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 lens is spot on. Did some research and before I got it and was not disappointed. I use this lens every day.

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.

Excellent lens for the money. I highly recommend this lens for anyone needing a nice zoom range for wildlife and sports.

Exactly as describe

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.
