This 100% all-content, junk-free website's biggest source of support is when you use those or any of these links to my personally approved sources I've used myself for way over 100 combined years 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 — and all of my personally approved sources allow for 100% cash-back returns for at least 30 days if you don't love your new lens. I've used many of these sources since the 1970s because I can try it in my own hands and return it if I don't love it, and because they ship from secure remote warehouses where no one gets to touch your new lens before you do. Buy only from the approved sources I've used myself for decades for the best prices, service, return policies and selection.

Canon RF 70-200mm f/2.8L IS USM Z on an EOS R1. bigger. Introduction topSample Images Intro New Good Bad Missing Specifications Accessories USA Version Performance Compared User's Guide
This is a "hybrid" lens, with additional gear teeth on its aperture and zoom rings for use with video rigs. I love this lens much more than the cheezier and five-years-older RF 70-200mm f/2.8L IS USM (2019-today) because this new lens zooms internally, requiring no more than the gentle stroke of a fingertip to zoom, while the older lens is a "pumper" that pumps in and out as you zoom. It's a dream to shoot with this new lens as obviously we are zooming all the time and the zoom ring glides back and forth easily, while the older lens has to be cranked in and out. The older lens was the only Canon f/2.8 tele I can recall that wasn't an internal zoom. The older lens was shorter for carrying when set to 70mm, while I greatly prefer shooting with this lens. The "Z" means there's an optional power zoom adapter available. I got mine at B&H, where it comes in black and in white. I'd also get it at Adorama in black, at Adorama in white, at Amazon or at Crutchfield, or get it used if you know How to Win at eBay.

This section applies in the U. S. A. only. Canon USA Warranty Card. bigger. Your lens must include a printed 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. If you have no card or the serial number doesn't match, you got ripped off with a gray market version intended to be sold in another country. This is why I never buy from any place other than my personally approved sources. You just can't take the chance of buying elsewhere, especially at any retail store where strangers have probably opened your completely unsealed box and played with your camera, 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. product in a gray-market box, 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 and never 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.

Overall performance top
Autofocus performance top
Bravo!
Manual Focus performance topManual focus is the usual on Canon. You may need to set some menus in some cameras to get manual-focus override, and no matter what you do, in SERVO AF mode all Canon EOS-R cameras, at least as of January 2025, will continue to autofocus as soon as you stop turning the manual focus ring. Sadly only Nikon has this all figured out today.
Focus Breathing performance topFocus breathing is the image changing size (growing and shrinking slightly) as focused in and out. It's important to cinematographers that the image not breathe (change size) as focus gets pulled back and forth between different actors as they speak. The image is said to breathe because it expands and contracts as the focus follows the dialog back and forth. The image from this lens grows only slightly as focused more closely. I doubt anyone will ever see it, unless shooting at f/22 where so much more is in focus.
Focus Distance Recording performance top

As always, if you want to throw the background as far out of focus as possible, shoot at 200mm f/2.8 and get as close as possible.
Distortion performance top
If you shoot raw data rather than JPG images, whatever software you use to create visible images from raw data may or may not correct the distortion as can be done in-camera as JPGs. You're on your own there; I don't bother with raw data. While Canon's own software probably also corrects this from RAW CR3 files, be warned that other brands of raw processing software probably won't correct the distortion. For more critical scientific use, 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.

Ergonomics performance top
Ergonomics are great! The aperture ring is for video. It only works on cameras introduced since about 2024 for still images. It lacks click stops, so it freaks me out because there is a slight time delay from turning this electronic ring until the camera updates its display with the new setting, so I never use this ring. I much prefer using the clicked dial on the camera, or assigning the front white control ring, which does have clicks, to set the aperture.
There may not be an always-responsive instant manual-focus override unless you enable this in a menu. Manual focus override never works in SERVO AF; while the lens will focus manually as you turn the ring, as soon as you stop the AF system takes over again.
Falloff performance top
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 save only raw data rather than create JPG images in-camera, whatever software you use to create visible images from that raw data later may or may not correct this as is done in-camera as JPGs. You're on your own there; I don't bother with raw data. If you go out of your way to turn off the correction, or possibly shoot raw files in some software, this is what you get:
Even if you go out of your way to turn the correction OFF it's not that bad in actual photos at f/2.8, and goes away by f/4. Bravo!
Filters, use with performance topThere's no need for thin filters. I can stack at least several standard 82mm filters with no vignetting at any setting on full-frame. Go ahead and use your standard rotating polarizer and grad filters.
Flare & Ghosts performance topThere is little to no problem with flare or ghosts. At worst, even with a filter, there will be just the slightest ghost of a setting sun opposite its place in the frame. This is excellent performance. See examples at Sunstars.
Lateral Color Fringes performance topThere are no color fringes when shot as JPG with the default Chromatic Aberration Correction in the Digital Lens Optimizer left 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 very slight green/magenta fringing at 70mm, none at the middle focal lengths and slight magenta/green at 200mm. This is superb performance; 1989's EF 80-200mm f/2.8L was much worse and there is no correction available. If you shoot raw data rather than JPG images you may — or may not — be responsible to correct this on your own. There is very slight green/magenta spherochromatism, which can cause color fringes on things that aren't in perfect focus at large apertures. Spherochromatism is a completely different aberration in a different dimension than lateral color fringes.
Lens Corrections performance topOther cameras may vary as the years roll on, but my EOS R1, R3, R5 II, R5, R5C, R6 II, R6, R, R8, RP, R7, R10, R50 and R100 all have options to correct for falloff (Peripheral Illumination Correction), Distortion and a Digital Lens Optimizer which corrects for a suite of other aberrations. All of these may be turned ON or OFF. 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. If you shoot raw data rather than JPG images, whatever software you use to create visible images from raw data may or may not correct these as is done in-camera as JPGs. You're on your own there; I don't bother with raw data.

Lens 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) 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 or smaller at ISO 1,600 or above at default sharpening in daylight of subjects at differing distances in the same image. People worry waaaaay too much about lens sharpness. It's not 1968 anymore when lenses often weren't that sharp and there could be significant differences among them; ever since about 2010 all new lenses are all pretty much equally fantastic. This lens is super sharp corner-to corner at every aperture, limited by your vision as an artist and of course by diffraction at the smallest apertures. Avoid f/16 and f/22 unless you really need them for depth of field because diffraction takes its toll. See also How to Calculate the Sharpest Aperture.

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 only minor green/magenta spherochromatism: Mondaine A132.30348.11SBB at close-focus distance, 12:22 PM, Monday, 25 November 2024.

Image Stabilization (VR) performance top
"Percent Perfectly Sharp Shots" are the percentage of hand-held, free-standing with no support or bracing, frames with 100% perfect tripod-equivalent sharpness as viewed at 300%. 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
I see 4 stops of real-world improvement.
At 200mm
I see 4½ stops of real-world improvement.
Sunstars performance topWith an 11-bladed rounded diaphragm, I get marvelous 22-point sunstars on brilliant points of light, bot only at the smallest apertures. Ignore the vertical smear at large apertures. This is a sensor artifact called interline transfer smear and is a camera, not a lens, defect. Likewise ignore the crazy rainbow dots at small apertures; these are sensor artifacts caused by interference among the divisions between pixels on the sensor. These are made visible because we're using enough exposure to show the dark underside of a huge palm tree, and then putting the blinding disk of the mid-day sun in it. Doing this will show everything due to the insane lighting range. Click any to enlarge: Click any to enlarge.

I got mine at B&H, where it comes in black and in white. I'd also get it at Adorama in black, at Adorama in white, at Amazon or at Crutchfield, or get it used if you know How to Win at eBay.
This internally-zoomed lens isn't much more expensive than the 5-years-older non-Z RF 70-200mm f/2.8L IS USM, which can be shorter but is a pumper zoom that changes size. They weigh about the same. This new lens works brilliantly with either the RF 2× Extender or RF 1.4× Extender teleconverters, but only one at a time. The older non-Z RF 70-200mm f/2.8L IS USM doesn't work with any converters. I'd ignore the old lens unless you have it in your bag most of the time and prefer its shorter collapsing pumper zoom (and its removable tripod collar). Otherwise I prefer the silky-smooth and balanced zooming of this newest internally-zoomed Z lens, and of course this new lens works with teleconverters that the old lens doesn't.

Manual-Focus Override user's guide topBy default, there is no always-responsive instant manual-focus override as we take for granted in our DSLRs. While newer cameras will do this by default in ONE SHOT AF, older 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" or "Electronic full-time MF" option in your AF menu (AF 6 in R5 II, R6 II, R7, R8 and R10, AF 4 in EOS R5 and EOS R6 or CAMERA 8 in EOS RP), and set it to either "One‑Shot‑> enabled," "One‑Shot‑> enabled (magnify)" or ON. Canon should have it set this way by default, but they didn't in older models. No big deal, and it usually works by default in newer cameras. In ONE SHOT AF manual focus now takes over and stays wherever you set the focus manually, however in SERVO AF this setting lets the lens focus manually as you turn the ring, but as soon as you stop, the AF system takes over again and keeps tracking focus! Oh well, this is still a defect in all Canon mirrorless cameras. (This works properly in the Nikon Z system, Nikon's ahead here.)
Canon RF 70-200mm f/2.8L IS USM Z. bigger. Full / 2.5m-∞ 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 while looking for distant subjects.
AF / MF user's guide topAF: Auto Focus, with instant manual focus override in ONE SHOT if set. MF: Manual Focus only.
STABILIZER user's guide topON / OFFLeave it ON unless you're on a very sturdy tripod, or if you're making exposures longer than about a second on any kind of tripod.
STABILIZER MODE 1 / 2 / 3MODE 1 (For still subjects): Corrects camera movement in all directions. MODE 2 (For panning on smooth motion like trains and airplanes): Corrects camera movement perpendicular to the panning direction. MODE 3 (For sports & animals): Same as MODE 2, but only compensates during exposure, not as you're viewing. It saves energy and is better for random motion.
Recommendations topSample Images Intro New Good Bad Missing Specifications Accessories USA Version Performance Compared User's Guide I got mine at B&H, where it comes in black and in white. I'd also get it at Adorama in black, at Adorama in white, at Amazon or at Crutchfield, or get it used if you know How to Win at eBay. White or black? White tells you, me and the world that you have a Canon L lens, and it stays cooler in dayllight. It also tends to stand out in public, so get black if you'd rather shoot undisturbed. I use a clear (UV) protective filter instead of a cap (exactly like an iPhone) 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 very best protective filter is the 82mm Hoya multicoated HD3 UV which uses hardened glass and repels dirt and fingerprints. The Nikon NC 82mm is also an excellent choice, but not as resistant to the environment, fingerprints and physical abuse as the HD3 UV. For much less money, the Hoya multicoated 82mm UV is also optically superb, but the Hoya HD3 is the toughest. Any of these filters protects as well and gives ultrasharp images, but since filters last a lifetime, you may as well get the best since the Hoya HD3 is tougher and stays cleaner than the others since it repels oil and dirt. The Nikon 82mm Polarizer is superb. 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. Since filters last a lifetime or more, there's no reason not to buy the best as it will last you for the next 40 years. Filters aren't throwaways like digital cameras which we replace every few years, like it or not. I'm still using filters I bought back in the 1970s! I got mine at B&H, where it comes in black and in white. I'd also get it at Adorama in black, at Adorama in white, at Amazon or at Crutchfield, or get it used if you know How to Win at eBay.
