Description

Perfect for wildlife, sports, travel and more, the RF100-400mm F5.6-8 IS USM is a compact, lightweight telephoto lens for EOS R Series cameras, offering a versatile zoom range that brings subjects closer with ease. The RF100-400mm F5.6-8 IS USM is similar in size to the EF 70-300mm F4.5-5.6 IS II USM lens, but not only reaches to 400mm, but also has fast Nano USM focusing and up to 6 stops of Coordinated IS when used in combination with an EOS R series camera featuring In-body Image Stabilization like the EOS R5 and EOS R6, or 5.5 stops with an EOS R/RP camera. Using a single Ultra Low Dispersion lens element towards the front of the lens group corrects chromatic aberration throughout the entire zoom range, making your images look crisp and colorful with minimal color blur. The RF100-400mm F5.6-8 IS USM lens can also accept both the RF1.4x and RF2x tele extenders giving you the effective maximum focal length of 560mm and 800mm respectively. With a control ring that allows for quick setting changes, including shutter speed and aperture, the RF100-400mm F5.6-8 IS USM lens puts quality, convenience and control in your hands.

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 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 aperture lens with greater separation. 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. ... show more

    • Long reach and light weight
Style: Lens Only
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. ... show more

This is my first and only lens, i absolutely love it on my Canon r7, its quite lightweight, it looks heavier than what it is, i got it mainly to shoot bird further away and its impressive especially when photographers call it a "budget lens". I even took a few macro shots with it using the raynox dcr 250 on top of it and it works okay, cant complain. here's a few of my favorite shots I took with it in the last 2 weeks.

    • Great lightweight lens
Style: Lens Only
This lens is amazing! It’s very clear and the functions work amazingly well. I bought it as a step down from my Sigma 600 mm because I needed something lightweight for hiking. It’s so light you barely can tell you are carrying such a strong zoom lens. It will obviously not replace my 600 mm but it’s definitely a great middle ground lens when you don’t want to lug around a 5 pound camera. I have an auto immune disease and there are days that I am too weak to pick up heavy objects. This lens helps me be able to still pursue my nature and wildlife photography even in my hard days. ... show more

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.

Amazing lens for wildlife and also capturing the moon! I’ve had a great time learning photography and using it on my hiking adventures. It fits perfect. Color is black. It’s large and heavy, but worth the pictures. Versatile enough for beginners.

    • Great lens for high school track / field and daytime soccer!
Style: Lens Only
Who/ What: I paired this with my R10 and am now barely out of the newb phase (bought 10 months ago). I bought this lens primarily to shoot my kids in track, soccer and X country meets and this lens has been great for those sports. Where: I'm shooting primarily outdoors in fields or on tracks (Hayward field once). Interestingly, I found that cloudy conditions were OK to shoot with this lens.... When I've tried to shoot practices under flourescent lights I saw some struggles with the auto focusing. When: The sports I'm shooting are generally in the day time, so the auto-zoom and tracking are spot on. I was able to consistently record and take pictures of my son throughout the track without any problems! I would have to switch to manual focus if there were many kids passing by in front of the lens, but the lens still handled that easily. Handles 15 image burst-shots with no problems (like taking pictures of the boys coming off the starting blocks), amazing pictures! When trying to shoot Soccer at dusk under lights, I had issues with the auto focusing and the light in the pictures, so I had to switch to the 70-200 in those cases. Why: So for being my first telephoto lens ever, I was very fortunate to have this lens without having to give up a kidney. I have since bought a 24-105 variable aperture and a 70-200 f4. The focusing on the 100-400 is faster than my 24-105 and yes the 70-200 is a GREAT lens at f4, but when I need to get the extra details on the other side of the track, I still need the reach of the 100-400 to get those shots. I highly recommend this lens! The only caveat is to expect diminishing performance as the sun starts to go down. ... show more

    • One of the best budget wildlife option out there
Style: Lens Only
There are only two things 'wrong' with this lens, and fixing them would undo the main advantages: It's not weather sealed It's f/5.6-8 Including weather resistance and/or a faster aperture would mean more cost, more size, and more weight, and the best things about this lens are how it packs a sharp, light, inexpensive lens into such a small form. The auto focus is great, and image quality is great, and it weighs less than almost another other 100-400 around(it might actually be THE lightest, not 100% sure). It has the added versatility of being 'semi-macro', with a maximum reproduction of around 0.4x life size, only slight less than the RF 35 and 85 'macro' lenses(both around 0.5x) Oh, also, it doesn't come with a lens hood, because Canon is cheap ... show more
