Introduction topSample Images Introduction Compatibility Specifications USA Version Performance Compared User's Guide Recommendations
This is an ultra-sharp and ultra-ultra compact professional telephoto zoom for Canon's EOS-R mirrorless system. On my EOS R5, autofocus is faster than my own eyes! Fulfilling the dream of mirrorless and quite different from Sony's huge, fat and bloated 70-200/2.8 GM, this Canon RF 70-200/4 is much smaller and lighter than any other 70-200mm, ever. It's about half the length of other 70-200/4s. It's the lightest 70-200mm ever made and focuses closer than any other 70-200mm at the long end. BRAVO! It's so light that it's trivial to shoot with one hand: Canon RF 70-200mm f/4L on EOS R5. bigger.
Canon RF 70-200mm f/4L IS. bigger. I got my RF 70-200/4L IS at B&H. I'd also get mine at Adorama, at Amazon or at Crutchfield, or used at eBay if you know How to Win at eBay.
New intro topSmaller, lighter and closer-focussing version of the Canon RF 70-200/2.8 L IS, which had been the smallest, lightest and closest-focussing 70-200 for two years. Smallest, lightest and closest-focussing 70-200mm ever. (Huge Nikon Z 70-200/2.8 can focus closer at 70mm, but not as close at 200mm where we need it.)
Good intro topUltra sharp. Super close focussing: the world's closest for a 70-200 at 200mm! Ultra fast autofocusing on the EOS R5 (faster than my own eyes), and fast even on the EOS RP. Smallest 70-200 ever. Lightest 70-200 ever. Great sunstars. Stops down to f/32. Fluorine coating to resist dirt and crud. Programmable third control ring. Image Stabilization claims 5 stops improvement, and 7.5 stops when used on the R5 or R6. Includes a great hood. Includes a carry sack. Made in Japan. 100% U.S.A.-based high-quality technical support at (800) OK-CANON.
Bad intro top
Missing intro topNo always-responsive instant manual-focus override. EOS R cameras need a menu setting changed for manual-focus override, otherwise the focus ring is always ignored in AF. Find the "Lens electronic AF" option in your AF menu (AF 4 in EOS R5 or CAMERA 8 in EOS RP), and set it to either "One‑Shot‑>enabled" or "One‑Shot‑>enabled (magnify)." Now manual focus override works if you turn the ring while continuing to hold the shutter halfway, but only after focus locks in ONE SHOT. No focus lock buttons; program one on the camera if you prefer. Nothing else missing, other than a lot of bulk and weight. Comes with a carry sack and a great hood — not that I ever use hoods.

It won't fit on, and cannot be adapted to, any DSLR because a DSLR has too much distance between its sensor and its lens mount flange. No teleconverters work with this lens. The RF 1.4× and RF 2× extenders both need to extend into the mount of the lens, and this lens has glass there so they interfere and won't mount.

A. only. Your lens must include a U. S. A. warranty card like the one shown above from Canon U.S.A., Inc. It should be on top inside your box as you open it. The serial number on the card must match the serial number on the bottom of your lens (I have two of these lenses so this card doesn't match the other lens in my photo). If you don't have this card or the numbers don't match, you got ripped off with a gray market version from another country. This is why I never buy anyplace other than from my personally approved sources. You just can't take the chance of buying elsewhere, especially at any retail store, because non-U. S. A. versions have no warranty in the U. S. A., and you probably won't be able to get firmware or service for it — even if you're willing to pay out-of-pocket for it when you need it! Shifty dealers may include color copies of a card from a legitimate U. S. A. lens in a gray-market box (some may even print the file above!), hoping you won't check serial numbers and catch their fraud. A card with the wrong serial number means nothing other than that you have no warranty coverage. The serial number on the box doesn't have to match, but it should. It will be hidden someplace on the sticker with all the bar codes. If not, it means a shady dealer took things out of boxes and was too sloppy to put them back correctly — and it means you got a used lens if anyone other than you took it out of the box. If a gray market version saves you $600 the risk might be worth it, but for $200 or less I wouldn't risk having no warranty or support. Always be sure to check yours while you can still return it, or just don't buy from unapproved sources or at retail so you'll be able to have your camera serviced and get free updated firmware as needed. Get yours from the same places I do and you won't have a problem.

I got my RF 70-200/4L IS at B&H. I'd also get mine at Adorama, at Amazon or at Crutchfield, or used at eBay if you know How to Win at eBay.
Overall performance topThe RF 70-200/4 makes history as the smallest and lightest 70-200mm ever made — and its optics, stabilization and autofocus are top-of-the-line as well. Bravo!
Autofocus performance topAutofocus is just about instantaneous on my EOS R5. It's so fast that I compared how fast my own eyes could focus from 3 feet (1m) to infinity, and the 70-200 & R5 combination are faster! It's fast on my EOS RP, but nowhere near as instantaneous as it is on my R5.
Manual Focus performance topManual focusing is entirely electronic; the manual focus ring isn't connected to anything other than a digital encoder. How to get manual-focus override.
Focus Breathing performance topFocus breathing is the image changing size as focused in and out. It's important to cinematographers that the image not breathe because it looks funny if the image changes size as focus gets pulled back and forth between actors. If the lens does this, the image "breathes" by growing and contracting slightly as the dialog goes back and forth. The image from this RF 70-200mm f/4L IS gets smaller as focussed more closely.
Bokeh performance topBokeh, the feel, character or quality of out-of-focus areas as opposed to how far out of focus they are, is good to neutral. Blur circles are simply circles and don't do anything weird. This is good. Here are photos from headshot distance wide-open:

As always, if you want to throw the background as far out of focus as possible, shoot at 200mm at f/4 and get as close as you can.
Distortion performance topThe RF 70-200/4 has the typical distortion seen in most 70-200mm lenses: moderate barrel distortion at 70mm, no distortion around 100mm and moderate pincushion distortion from 135~200mm. My EOS R5 doesn't bother correcting it by default. For more critical scientific use, turn on your camera's automatic correction, or use these corrections in Photoshop's lens correction filter to JPG images. These aren't facts or specifications, they are the results of my research that requires hours of photography and calculations on the resulting data.
If you shoot raw you'll probably get no automatic corrections, depending on the software you use to create images from the raw data.
Ergonomics performance topErgonomics are great; everything is right where we expect it. Zooming is a direct mechanical ring. Focus is entirely electronic. How to get manual-focus override. It's not apparent, but there is a third programmable and detented control ring at the front of the lens:
The slide switches cover everything (Focus Limit, AF/MF and Stabilizer) and are right where we expect them: Canon RF 70-200mm f/4L IS USM. bigger.
Falloff performance topFalloff is invisible, at least shooting with the default falloff correction ("peripheral illumination correction") ON. I've greatly exaggerated the falloff by shooting a gray field and placing these on a gray background; it will not look this bad in actual photos of real things:
If you're silly enough to go out of your way to turn falloff correction ("peripheral illumination correction") OFF, then you still won't see any in actual shooting, save for wide-open at the longest end. I've greatly exaggerated the falloff by shooting a gray field and placing these on a gray background; it will not look this bad in actual photos of real things:
Filters, use with performance topThere's no need for thin filters. You can stack many 77mm filters without vignetting. 77mm is a much larger filter than needed by this lens; it's more cosmetic to fit the barrel outer diameter than necessary to cover the optics. In fact, you could use a step-down ring to use a 58mm filter and be just fine. Go ahead and use your standard rotating polarizer and grad filters.
Flare & Ghosts performance topI see no problems. See examples at Sunstars.
Focal Lengths, actual performance topAt infinity where you need it, you get the full 70~200mm range. Canon plays the usual optical tricks to get us ultra-close focusing throughout the entire zoom range, which means if you're weird enough to adapt a manual-focus fixed 200mm lens to your EOS R series camera and compare the two at close distances, of course this lens isn't quite 200mm at those close distances — but that's OK because it's far more important to have close focussing. This effect is also seen as focus breathing.
Lateral Color Fringes performance topThere are no color fringes when shot as JPG with the default Chromatic Aberration Correction inside Digital Lens Optimizer left at ON. if you go out of your way to turn this OFF (or shoot raw and then use non-manufacturer software to process that data into images) then there is just the tiniest invisible amount of green-magenta fringing at 70mm, none in the middle of the zoom range, and the tiniest invisible amount of magenta-green at 200mm This is superb performance; bravo!
Lens Corrections performance topOther cameras may vary, but my EOS R5, EOS R6 and EOS RP all have options to correct for falloff (Peripheral Illumination Correction), Distortion and a Digital Lens Optimizer which correct for a suite of other aberrations. The EOS R has this, too; I just don't have one handy to check the specifics with this lens. Falloff and the Digital Lens Optimizer are ON by default. Distortion correction is OFF by default. Feel free to turn it on for critical use. If you turn off the Digital Lens Optimizer, you are then offered à la carte ON/OFF options for Chromatic Aberration Correction and Diffraction Correction — at least on my EOS R5, EOS R6 and EOS RP.
Macro Performance performance topMacro is great; the 70~200 focuses super-close, the world's closest-focussing 70-200mm zoom at 200mm, and it's super-sharp even wide-open:

This is made as Canon makes most of their pro lenses today: plastic on the outside for weight and to keep your fingers from freezing to it in the cold, and lots of metal on the inside where it counts. As 70-200/4L lenses go, this RF lens is a very easy-to-carry and lightweight lens. Part of this is the use of a lot more plastic than on the other lenses; this RF lens is well made, and well made with a lot more plastic than other L lenses.

Sharpness performance topLens sharpness has nothing to do with picture sharpness; every lens made in the past 100 years is more than sharp enough to make super-sharp pictures if you know what you're doing. The only limitation to picture sharpness is your skill as a photographer. It's the least talented who spend the most time worrying about lens sharpness and blame crummy pictures on their equipment rather than themselves. Skilled photographers make great images with whatever camera is in their hands; I've made some of my best images of all time with an irreparably broken camera! Most pixels are thrown away before you see them, but camera makers don't want you to know that. If you're not getting ultra-sharp pictures with this, be sure not to shoot at f/11 or smaller where all lenses are softer due to diffraction, always shoot at ISO 100 or below because cameras become softer at ISO 200 and above, avoid shooting across long distances over land which can lead to atmospheric heat shimmer, be sure everything is in perfect focus, set your camera's sharpening as you want it (I set mine to the maximum 7,5,5) and be sure nothing is moving, either camera or subject. If you want to ensure a soft image with any lens, shoot at f/16 at ISO 1,600 at default sharpening in daylight of subjects at differing distances in the same image. People worry waaaaay too much about sharpness. It's not 1968 anymore when lenses often weren't that sharp and there could be significant differences among them; today they are all pretty much equally fantastic. This is one of the sharpest zooms ever made, and in actual use, it's sharp from edge to edge all the time. Sharpness is the least important lens factor today; heck, even my EF 70-200mm f/4L IS (first version from 2006) is stellar on my 50MP 5DS/R (Canon's highest resolution camera of all time), as is my original 1989 EF 80-200mm f/2.8L. This lens is so sharp that I should turn down the sharpening in my R5. I usually have my R5 set to 7,5,5 for sharpening (under MENU > CAMERA 3 > Picture Style), and at this 7,5,5 setting this lens is so sharp that it leads to "ringing" or white haloes around sharp lines. How's that for extreme sharpness? Obviously we all have different tastes, so set these as you prefer.

Spherochromatism performance topSpherochromatism, also called secondary spherical chromatic aberration or "color bokeh," is an advanced form of spherical and chromatic aberration in a different dimension than lateral chromatic aberration. It happens mostly in fast normal and tele lenses when spherical aberration at the ends of the color spectrum are corrected differently than in the middle of the spectrum. Spherochromatism can cause colored fringes on out-of-focus highlights, usually seen as green fringes on backgrounds and magenta fringes on foregrounds. Spherochromatism is common in fast lenses of moderate focal length when shooting contrasty items at full aperture. It goes away as stopped down. It has a little bit of cool - warm spherochromatism, but nothing to get excited about: Mondaine A132.30348.11SBB at close-focus distance, 11:28 AM, 18 March 2021.

Image Stabilization performance topOptical Image Stabilization (OIS or IS) works great at 70mm but not so well at 200mm. I get perfect sharpness most of the time hand-held, standing with no bracing or support, most of the time at 1/8 at 70mm but only at 1/60 at 200mm. "Percent Perfectly Sharp Shots" are the percentage of frames with 100% perfect tripod-equivalent sharpness I get when I'm shooting hand-held while free-standing with no support or bracing. Hand tremor is a random occurrence, so at marginal speeds some frames will be perfectly sharp while others will be in various stages of blur — all at the same shutter speed. This rates what percentage of shots are perfectly sharp, not how sharp are all the frames:
At 70mm on EOS R5 (with additional in-body stabilization and Firmware 1.2.0)
I see about five stops of real-world improvement.
At 200mm on EOS R5 (with additional in-body stabilization and Firmware 1.2.0)
I see only about two stops of real-world improvement, which is poor.

Teleconverters performance topNo teleconverters work with this lens. The RF 1.4× and RF 2× extenders both need to extend into the mount of the lens, and this lens has glass there so they interfere and won't mount.
Tripod Collar performance topThere is NO tripod collar. This lens is too small to need one; don't worry about it.

Canon EF 100-400 II, EF 70-200/4, RF 70-200/2.8 & RF 70-200mm f/4 (all L IS). bigger. These are all ultra-sharp lenses, and they all focus very close. This newest RF 70-200mm f/4L IS is the smallest, lightest and closest focussing, however due to its 400mm focal length the EF 100-400 II has the largest macro reproduction ratio by a slight margin of 1:3.2 (0.31×).

I got my RF 70-200/4L IS at B&H. I'd also get mine at Adorama, at Amazon or at Crutchfield, or used at eBay if you know How to Win at eBay.
Manual-Focus OverrideBy default, there is no always-responsive instant manual-focus override as we take for granted in our DSLRs. EOS R cameras need a menu setting changed for manual-focus override, otherwise the focus ring is always ignored in AF. Find the "Lens electronic AF" option in your AF menu (AF 4 in EOS R5 and EOS R6 or CAMERA 8 in EOS RP), and set it to either "One‑Shot‑>enabled" or "One‑Shot‑>enabled (magnify)." Canon should have it set this way by default, but they don't. No big deal now that I figured it out. Now manual focus override works if you turn the ring while continuing to hold the shutter halfway, but only after focus locks in ONE SHOT. The focus ring is ignored in SERVO.

Full / 2.5m-∞ Switch user's guide topThis is a focus limiter. Leave it in FULL. The 2.5m-∞ position prevents the lens from autofocusing closer than 2.5 meters (8 feet). Use this setting only if you're having a problem with the lens attempting to focus on irrelevant close items, or if for some reason the lens is "hunting" from near to far looking for distant subjects.
AF - MF Switch user's guide topAF: Auto Focus, with instant manual focus override in ONE SHOT if set. MF: Manual Focus only.
Stabilizer Switches user's guide topON / OFFLeave it ON unless you're on a very sturdy tripod, or if you're making exposures longer than a second on any kind of tripod.
Stabilizer Mode 1 / 2 / 3Mode 1: Normal. Mode 2: Panning. Mode 3: Same as mode one, but saves power because it only works when you take the picture, not when you're composing.
Tripod Collar user's guide topThere is NO tripod collar. This lens is too small to need one; don't worry about it.
Recommendations topSample Images Introduction Compatibility Specifications USA Version Performance Compared User's Guide Recommendations The RF 70-200/4L IS USM offers full f/4L-grade performance in the smallest package ever, and focuses super-close and utra-fast. I got my RF 70-200/4L IS USM at B&H. I'd also get mine at Adorama, at Amazon or at Crutchfield, or used at eBay if you know How to Win at eBay. This lens is super compact and high-performance, however and when I'm shooting something serious I prefer my much larger EF 100-400mm L IS II because I often use the 200-400mm range, and my 100-400 focuses almost as close and almost as fast, and it works great even with stacked -II extenders. I haven't used a 70-200 lens in years ever since I upgraded to the EF 100-400mm L IS II, which I still prefer to the RF 100-500mm (why?). No extenders work with this RF lens. I use a clear (UV) protective filter instead of a cap so I'm always ready to shoot instantly. I only use a cap when I throw this in a bag with other gear without padding — which is never. The UV filter never gets in the way, and never gets lost, either. The best protective filter is the 77mm Hoya multicoated HD3 UV which uses hardened glass and repels dirt and fingerprints. For less money, the B+W 77mm 010 is an excellent filter, as is the multicoated version and the basic multicoated Hoya filters or the 77mm Nikon Clear (NC - UV), but the Hoya HD3 is the toughest and the best. Filters last a lifetime, so you may as well get the best. The Hoya HD3 stays cleaner than the others since it repels oil and dirt, and will outlast this lens. All these filters are just as sharp and take the same pictures, the difference is how much abuse they'll take and stay clean and stay in one piece. This all-content, junk-free website's biggest source of support is when you use those or any of these links to approved sources when you get anything, regardless of the country in which you live. Canon does not seal its boxes in any way, so never buy at retail or any other source not on my personally approved list since you'll have no way of knowing if you're missing accessories, getting a defective, damaged, returned, non-USA, store demo or used lens. I use the stores I do because they ship from secure remote warehouses where no one gets to touch your new camera before you do. Buy only from the approved sources I use myself for the best prices, service, return policies and selection. Thanks for helping me help you! Ken.
