Canon RF24-70mm F2.8 L IS USM Lens review

Are you considering the Canon RF24-70mm F2.8 L IS USM Lens as your next go-to standard zoom for an EOS R camera?

Overall impression

I feel this lens is one of those “do-it-all” pieces of glass that makes shooting more enjoyable and more reliable. From the moment I started using the Canon RF24-70mm F2.8 L IS USM Lens, I appreciated how it balanced image quality, handling, and features that matter for both stills and video. It’s a solid L-series standard zoom that, in my experience, earns its place in a full-frame mirrorless kit.

I like having a compact spec summary like this up front because it sets expectations. The constant f/2.8 and built-in IS are the headline features for me.

What the specs mean in practice

Having a constant f/2.8 gives me consistent exposure and depth-of-field control throughout the zoom range, which is useful during events or run-and-gun shooting. The built-in optical IS rated up to 5 stops is a practical advantage for handheld low-light work when I’m not using a tripod. Nano USM autofocus feels modern — it’s geared for quiet and smooth performance, which I appreciate when shooting both photos and video.

Optical performance

I rely on lenses to deliver sharp, contrasty images with natural color reproduction, and the RF24-70mm f/2.8 L generally does that across its focal range. In my shoots I found the center sharpness to be very strong at all focal lengths when stopped down slightly (around f/4–f/8). Wide open at f/2.8, it maintains good subject separation but I do notice some micro-softness toward the edges at the extremes of zoom, which is typical for zooms of this class.

Chromatic aberration is well controlled in normal shooting conditions, and longitudinal chromatic aberration (color fringing in out-of-focus highlights) is modest and manageable in RAW editing. Contrast and color are pleasant straight out of the camera; Canon’s color science combined with the lens coatings gives images a pleasing tonality that I didn’t feel needed heavy correction.

Sharpness across the frame

When I shot landscapes or architecture, I stopped to f/5.6–f/8 and saw very solid corner-to-corner performance for prints and client work. For portraits and smaller crops, the center sharpness at 50–70mm is excellent even at f/2.8. If you’re pixel-peeping at 100% and comparing to prime lenses, you’ll notice the usual zoom compromises, but for everyday work the lens delivers impressively.

Handling of flare and contrast

I encountered strong sun-in-frame scenarios and the lens handled flare pretty well thanks to modern coatings. I still try to block direct sun with my hand or the hood for critical contrast, but in backlit portraits or high-contrast scenes the lens retained color and contrast better than I expected.

Aperture and bokeh

One of the big reasons I reach for this lens is the constant f/2.8 aperture. It’s a very useful aperture for low-light and for controlling depth of field. I use f/2.8 for subject isolation in portraiture and f/4–f/5.6 for sharper group shots or when I want more depth.

The bokeh—background blur—at 70mm and f/2.8 is pleasing and generally smooth. Specular highlights render softly and ringed or nervous bokeh is not a common issue in my experience. Mid-frame to background transitions are natural enough that I feel comfortable using the lens for environmental portraits and event coverage where background separation matters.

Creative control with aperture

I appreciate that f/2.8 is available across the entire zoom range, so I don’t have to change exposure or depth-of-field strategy when zooming in quick setups. That constant speed helps with consistent framing when the light is changing, like during indoor ceremonies or evening receptions.

Autofocus and image stabilization

Autofocus performance matters a lot to me because I shoot both stills and video. Canon’s Nano USM system in this lens feels fast and quiet. For single-shot photography, AF acquisition is snappy and reliable for everyday subjects. For continuous autofocus in event situations, tracking was solid in my hands—again, within expectations for professional zooms.

The built-in optical image stabilization rated up to 5 stops is a major benefit for handheld shooting. I tested handheld shooting at slower shutter speeds and felt confident down to shutter speeds I wouldn’t have attempted without IS. When combined with bodies that have in-body stabilization (IBIS), like the EOS R5 or R6, I found the stabilization synergy to be even better—handheld stills became much easier in dim light.

AF for video

For video, the Nano USM permits smooth transitions that feel natural and not abrupt. Focus breathing is modest, which I appreciated when pulling focus in narrative or interview setups. The quiet motor also helps keep autofocus noise out of internal audio recordings, although I still recommend using dedicated microphones for critical audio.

Close focusing and working distance

The minimum focusing distance of 0.69 ft (0.21 m) at 24mm and 1.25 ft (0.38 m) at 70mm lets me get reasonably close to subjects for tight details and more dramatic wide-angle perspectives. I enjoy using the wide end for environmental close-ups and the tele end for tighter detail without having to change lenses.

Practical close-up uses

I often use the 24mm setting for low-angle close portraits and product detail shots where I want to include context. At the tele end, the close focus gives me head-and-shoulders framing with good background compression. It’s not a macro lens, but it’s versatile enough for casual close-up work.

Build quality, handling, and ergonomics

As an L-series lens, I find the RF24-70mm f/2.8 L feels solid and professional in the hand. The build inspires confidence—metal mount, robust construction, and a finish that resists everyday wear. Canon’s L lenses have a reputation for weather resistance, and I’ve shot this lens in light rain and dusty conditions without issue when using a weather-sealed body.

The control ring is a wonderful feature for me. I customize it to control aperture or exposure compensation depending on the shooting task, and it’s handy for quick adjustments without taking my eye from the viewfinder. Zoom and focus rings are smooth, and the overall balance on a mid-size mirrorless body is comfortable for long shoots.

Weight and balance notes

This lens is not the lightest in the lineup—constant f/2.8 zooms are inherently heavier—but I felt the weight was reasonable and the lens balances well on RF bodies like the EOS R6. For long handheld days, I do sometimes prefer a lighter walk-around option, but when image quality and low-light capability are priorities, I don’t mind the extra heft.

Video performance and filmmaking use

I use this lens frequently for run-and-gun video and interviews. The combination of Nano USM AF, built-in IS, and a constant aperture makes it highly practical. Smooth focus pulls are easier thanks to Nano USM’s linear-like behavior, and I find it’s a good choice for single-operator filmmaking where I need one lens that handles a variety of shots.

Rolling shutter and stabilization

If you pair this lens with an IBIS-enabled camera, you can often avoid a gimbal for many handheld sequences. I still lean on gimbals for complex moving shots, but for interviews, cutaways, and event coverage the stabilization is more than adequate. Autofocus is quiet and unobtrusive so it doesn’t interfere with on-camera audio.

Real-world shooting scenarios

I’ve used the RF24-70mm in weddings, corporate events, travel, street photography, and portrait sessions. Here’s how I typically use the focal lengths:

24–35mm: Environmental portraits, groups, interiors, travel scenes where context matters.
35–50mm: Street work, casual portraits, documentary sequences—this is my everyday keeping-it-real range.
50–70mm: Headshots, tighter portraits, product detail, and compressing backgrounds for a more flattering look.

In wedding coverage I rely on the lens for ceremony and reception work because it gives me the speed for low light (f/2.8), reach when I need it, and the versatility to handle everything from vows to candids without lens changes. In travel and street work, I appreciate the focal flexibility so I can react quickly to scenes.

Pros and cons

I find it helpful to summarize practical strengths and trade-offs so you can weigh them against your needs.

Pros:

Constant f/2.8 aperture across the zoom range gives consistent exposure and depth-of-field control.
Optical IS up to 5 stops helps handheld shooting in low light.
Nano USM autofocus is smooth, fast, and quiet for both stills and video.
Excellent center sharpness and generally high image quality.
Control ring adds tactile, convenient access to settings.
Robust L-series build with weather resistance for professional use.
Very versatile focal range for events, portraits, travel, and video.

Cons:

Heavier and larger than equivalent f/4 or prime options; not the lightest choice for long hikes or minimalist kits.
Edges and corners can be softer wide open at extreme focal lengths compared to fast primes.
Price is higher than consumer-grade zooms due to L-series features and f/2.8 performance.

I found these pros and cons to be accurate for my typical shooting style: I prefer quality and flexibility over the smallest possible kit.

How it compares to alternatives

Comparing this lens to other options helps clarify where it shines. Here’s how I think about it based on experience and general knowledge about camera systems.

RF 24-105mm f/4: The f/2.8 RF24-70 is faster and generally sharper, especially in low light. The 24-105mm covers more range and is lighter and often less expensive, but it doesn’t give the same low-light capability or subject separation at f/2.8.
Older EF 24-70mm f/2.8 (with adapter): Optically comparable in many ways, but the RF version benefits from updated optics and native RF mount advantages like shorter flange distance and improved coatings. Autofocus and stabilization in the RF native lens feel more integrated.
RF 24-70mm f/4 or primes: The f/2.8 gives a clear advantage for low-light and subject isolation, while the f/4 or primes can be smaller, lighter, and sometimes sharper in their specific focal lengths. It’s a trade between convenience and optical speed.

If you prioritize low-light performance and need a single professional zoom to handle most assignments, I think the RF24-70mm f/2.8 L is a strong choice. If you prioritize weight and extended reach, other options might appeal more.

Practical tips for getting the most from the lens

I’ve learned a few practical habits that make this lens perform even better for me. These tips may help you in daily shooting.

Use the control ring: I set it to aperture control for portraits and to exposure compensation for events—either way it speeds up my workflow.
Combine IS with IBIS: If you own an EOS R body with IBIS, leave both IS and IBIS enabled and let the camera/lens handshake work for maximum stability.
Stop down a bit for edge sharpness: If you need the best corner detail, stopping to f/5.6–f/8 helps tighten up the entire frame.
Use center AF when critical: For highest sharpness on single-subject portraits, I compose and focus with center AF then recompose if needed.
Keep a polarizer or ND handy: For landscapes and video in bright light, a circular polarizer or ND filter can help control exposure and reflections. (Check the exact filter size in official specs or with the retailer.)

Accessories and care

I treat this lens as a workhorse. I use the matching lens hood (usually included with Canon L lenses) for protection and flare control, and I store the lens in a padded bag when traveling. I recommend using a UV or protective filter if you often shoot in gritty conditions, though I’m careful to use good-quality filters to avoid image degradation.

Cleaning and maintenance

I clean the front element with a blower, microfibre cloth, and minimal lens cleaner when necessary. The weather sealing offers reassurance, but I still avoid submerging the lens or exposing it to heavy salt spray without proper protection.

Who should buy this lens?

I recommend this lens for photographers and videographers who need a single, high-performance standard zoom that handles a wide range of assignments. Specifically, I’d say:

Wedding and event shooters who want low-light capability and flexibility.
Portrait photographers who rely on a fast, versatile zoom.
Hybrid shooters who switch between stills and video and need quiet AF and good stabilization.
Professionals who require rugged build and consistent f/2.8 performance.

If you’re a casual user who values minimal weight above all else, or if you primarily shoot static studio work where you can use primes, you might opt for lighter or more specialized lenses instead.

Common questions I get about the lens

I often get asked a few recurring questions from friends and clients when they see this lens in my bag. Here are concise answers I give based on my experience.

Is the f/2.8 worth the extra weight and cost? I think so if you frequently shoot in low light or need more control over depth of field. For casual daytime work, f/4 alternatives may suffice.
How does stabilization compare to IBIS? Optical IS up to 5 stops is excellent by itself, and when paired with an IBIS body (R5/R6), I see improved handheld performance beyond either system alone.
Is it weather sealed? As an L-series lens, it’s designed for professional use and includes weather-resistant construction; I’ve used it in light rain and dusty conditions without issues.
Does it autofocus silently during video? Nano USM is very quiet and smooth, so it’s great for video AF; however, always use external audio and monitor sound for critical shoots.

My final verdict

I consider the Canon RF24-70mm F2.8 L IS USM Lens to be a reliable, high-performance standard zoom that suits a wide range of professional and enthusiast needs. In my hands it delivered consistent image quality, practical stabilization, and autofocus performance that made both photos and videos easier to capture under real-world conditions. The constant f/2.8 aperture, control ring, and L-series build are features I value highly.

If I were building or upgrading my kit and needed a workhorse zoom that covers the most-used focal lengths for events, portraits, and run-and-gun video, this lens would be near the top of my list. It’s a tool that balances creative control, durability, and everyday practicality—exactly what I look for when I commit to a single, go-to zoom.

Closing thoughts and buying considerations

When deciding whether to buy, think about your priorities: do you value low-light performance and the convenience of a single professional zoom? Are you willing to carry a slightly heavier lens for better speed and build? If your answer is yes, this lens is a strong match. Try it on your camera body if you can, and consider how it balances with other lenses in your kit—often it replaces several lenses and simplifies a workflow.
