Lightweight, Inexpensive, but VERY SLOW!
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.

Good lens for the price but quality suffers
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.

RF100-400 + 2x extender wins vs. RF200-800
I am writing this review as a previous owner of this lens because for whatever reason, it won't let me write a review for the RF200-800 lens, which I purchased to replace my RF100-400. That being said, I wish I still had this lens, for 3 main reasons: 1. This lens @ $649 + $450 2x extender (refurbished) is effe

The best lens you can have is the one that is with you
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,

Great lens for the price!
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!

My favorite lens for my R10. It meets my needs for the pictures I take

NOT a DSLR lens!!
thanks for making me waste my time and money buying this MIRRORLESS camera lens that you have listed in the DSLR category. Please fix your website and maybe not be so vague about what cameras this works with!

Canon RF telephoto zoom lens - 100 mm - 400 mm is rated 4.40 out of 5 by 23.
Rated 5 out of 5 by from RF100-400 + 2x extender wins vs. RF200-800 I am writing this review as a previous owner of this lens because for whatever reason, it won't let me write a review for the RF200-800 lens, which I purchased to replace my RF100-400. That being said, I wish I still had this lens, for 3 main reasons: 1. This lens @ $649 + $450 2x extender (refurbished) is effectively the same focal length and aperture as the RF200-800 for ~$600 less. 2. The RF100-400 + 2x extender is VERY portable in comparison to the much larger RF200-800. 3. The RF200-800 has a much larger front lens and picks up a lot more dust than the RF100-400, so you will spend a lot more time trying to keep the RF200-800 clean. As far as image quality is concerned, I can't say the RF200-800 is noticeably better. This red tail hawk photo was taken with RF100-400 + 2x extender and is one of my favorites.

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!

Rated 5 out of 5 by from Great telephoto lens for a great price I'm using the lens for travel photography, sports photography and sports video with an R6. It is fantastic for the price. Focus is sharp and image quality is great. The small size and light weight makes it a good fit for travelers who don't like to cary a large camera bag.

Rated 5 out of 5 by from Get What You Pay For The lens is light weight and does not need a tripod-ring. It is well made and feels solid in the hands. When there is plenty of light or sunshine the lens performs pretty well. I have used this lens for a few days now shooting my grandsons games and birds in the backyard this weekend and I am not very impressed. Even when I got a keeper, it was still vaguely out of focus or just not crisp. I use an R6. When shooting flagfooball yesterday my keeper ratio was terrible; something as low as 2 in ten were keepers. When it did miss focus, you could not determine where the camera was aiming; nothing was in focus. I was shooting handheld and it was a pretty bright day so there should have been plenty of sunshine. I also tested in lower light conditions, just overcast. It was hit or miss in this situation. I also found it slow to focus and especially in low light.

Rated 5 out of 5 by from It's not a great but decent lens especially when you consider price I purchased the lens about 6 months ago and use it with my new EOS R7 body, purchased at the same time. It's not as good as I thought it to be. It was giving great pictures for first couple of months. Then the quality deteriorated. The lens struggled to focus even in bright daylight and in high contrast spots. The pictures came out was not sharp at all. I wanted to replace the lens but the Canon return policy was not offering it. So I had to send the lens for repair. The service center told that they did not find any issue with the lens. That's frustrating. They just cleaned it.

Rated 5 out of 5 by from Great Lens Great lens for the price, feels solid handling it and it's lightweight. The size of the lens as well makes it easy to travel with. I use this lens for aviation and sports photography so the fast auto focusing is really nice, especially with faster moving action.

Rated 5 out of 5 by from Good quality lens I’ve had the RF 100-400 for 3 months now. It’s one of my favorite lenses. I use it on my Canon RP during daytime walks. This is a hobby of mine. I like capturing images of birds, butterflies, flowers, and landscapes. The autofocus is solid. I don’t have a lens hood or an nd filter yet I just shoot the lens s is. It feels nice and solid. I like the control ring. Very enjoyable.

Rated 5 out of 5 by from Don't let the price fool you I purchased an R6 Mark ii in November and only had the 24-105 mm lens. Which is fine but I needed a zoom lens. The other 100-400 mm white lenses were outside my budget. I was reluctant to buy this lens because, come on...it's $650. How good can that be? I've been pleasantly surprised with this lens as I'm learning to take bird photos. I think I want the 200-800 mm that is back-ordered/new next. I'm giving it 4.5 stars.

Rated 5 out of 5 by from Fantastic Value 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.

Rated 5 out of 5 by from I love this lens. 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.
