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

Took this on vacation recently. While it's a little bulky (expected), it's lightweight, easy to use, works great. The image quality, image stabilization, and both auto-focus and manual focus are excellent. Everything works smoothly. Great option for any of Canon's APS-C mirrorless R series cameras. I believe it works on the full-frame versions too, but with a cropped image size since it's designed for the APS-C models.

It's not fast but I'm NOT using film with a fixed speed and my camera goes up to ISO 100k or so making the small maximum aperture only of concern if I have shots where I care about lower depth of field. It's extremely light and about twice the maximum focal length and a third of the weight of of a faster 70-210mm I also own. Given that I have a 2x converter as well the Canon 100-400mm operates for me between 100mm and 800mm. I got it very cheap due to a Canon discount and a work bonus but given the picture results I've had, it was easily worth it at the discounted price alone. Long range landscape shots like high mountain positions are excellent and either the low weight, stabilization or both make for sharp shots at long range even when hand held. With my 2x converter it completely fills the gap between a 24-105mm and an 800mm super telephoto instead of leaving the gap I have remaining with an existing 70-210mm zoom. I'm very happy with my Canon 100-400mm f5.6-8.

I have been throughly impressed with this lens in multiple situations. It has a great focal range which allows for a wide range of applications. I’ve used this lens for landscape, wildlife, architectural, and macro photography with it performing best in wildlife and macro photography. This lens is able to focus on objects at about 3 feet when on 100mm focal length. This makes it great for capturing large amounts of detail with a macro like look. You’re also able to take advantage of the telephoto compression, making photos look like they were taken with a slightly lower F stop. When using this lens for nature photography, I found it to have the bare minimum focal range required. You are able to capture a good amount of detail at 400mm but at this range even at the aps-c equivalent of just over 600mm, I found it to just barley be able to capture subjects without cropping in post editing. This range is still by all means usable though and you have to remember the small size of this lens compared to others. The biggest draw back to this lens is its low light performance. While its still usable, it can be challenging to obtain high detail images without sizable amounts of noise. At the end of the day, this is a great lens that I use often on my Canon R50 due to its versatility, portability, and effectiveness. There really isn’t anything else even remotely close to this price point which will compare.

I bought this lens to go with my new Canon R7. Or maybe I bought the R7 to go with this lens? I really wanted a lighter weight lens and camera for carrying with me when hiking or birding. My 6d / 100-400mm F4-5.6 IS L (Mark 1) was too heavy to carry around my neck for hours. I got a Sony RX10 mark IV bridge camera which was a great size and weight, but the picture quality was not as good as I wanted. This lens and body combo is hopefully the answer to my problems. The lens itself is pretty impressive in terms of its length and weight. Sure, I wish it were shorter, but for 400mm, I can't really complain. I also wish it had a wider aperture, but for the lower price and weight, that is obviously the compromise you have to make. The sensor noise performance of the R7 eliminates some of the downside of the slow lens, but it can't help create the nice background blur that a fast lens will have. The image stabilization combo of the lens and body works exceptionally well. I have been getting sharp shots at 400mm with 1/250s handheld with my shaky hands. Images look crisp to me and autofocus is very fast and quiet. One thing I have not gotten used to is the zoom ring works backwards from every other lens I have. Maybe someday I will get used to it, but for now, every time I try to use it I start with rotating it the wrong way. On the plus side, there is no zoom creep when I am walking around with this lens around my neck. There is a lock where you can fix it at 100mm, but I have never had to use it. I am a little disappointed there is no weather sealing on this lens. I'd have paid a little more to have some basic weather sealing on it as I don't want to have to worry about using it in mist or rain. I'm not taking any stars off for those items that disappoint me about this lens as they are either compromises for size and weight, or were known limitations when I bought the lens and not a surprise. Overall, 5 stars as I am very happy carrying this lens around for hours taking bird photos.

It's well-built, lightweight, compact, convenient, and has good stabilization. Of course, I would have liked better aperture, and it's unsuitable in low light conditions. Nevertheless, it's a good lens.

I am a professional photographer, but didn't really "need" this lens for my daily work. I was just enjoying photographing birds and this was a "cheap-by-lens-standards" impulse buy. The lens surprised me, and I've been impressed by it. I was worried about f/8 at the long end, but the compression at 400mm still allows for the semi-shallow focus look. It's harder to get a great image when the light is low, and performs best on a sunny day. I've paired it with a Canon R5, so at least the sensor does well at a higher ISO. At first I thought the AF was a little sluggish, but I think it might've been my own user error, had good luck with eye AF settings, able to grab focus on little, erratic birds. The lens is SUPER light, which I love. The lack of weather sealing worries me, I live in Hawaii-it is humid- but I toss it in a dehumidifier box after a misty day. If I continue with bird photography and actually sell images I'd probably invest in the 100-500, but for now, this is a great lens to play with.

Extremely sharp, a good starter zoom lens for wildlife, lightweight compared to other lenses of similar mm length…

Mesmo tendo a maioria das avaliações positivas, fiquei receosa em comprar por conta de algumas pessoas terem relatado o recebimento de uma lente usada. Mas meu produto chegou ontem (muito antes do prazo de entrega) e é uma lente nova. Chegou muito bem embalada e sem nenhuma avaria. Já fiz alguns testes em casa e aparentemente está funcionando tudo ok. Então para esse primeiro momento eu daria nota 10, tanto pela entrega rápida quanto pelo produto ser novo. Continuarei testando durante essa semana para ter certeza que está 100% funcionando.

Comme d’habitude chez canon, matériel correct pour la gamme, j’ai enlevé une étoile car il y avait déjà une poussière sur une lentille interne quand j’ai déballé l’objectif, l’ensemble n’étant pas tropicalisé …

Funciona muy bien.

No puedo opinar mucho ha llegado golpeado y lo necesitaba para un trabajo 😔😔
