Canon RF 24-70mm f2.8L IS USM vs Canon RF 24-105mm f2.8L IS USM Z (April 2026)

After spending months shooting with both the Canon RF 24-70mm f/2.8L IS USM and the Canon RF 24-105mm f/2.8L IS USM Z, I can tell you this: choosing between them comes down to one fundamental question. Do you prioritize portability or versatility?

Both lenses represent Canon’s finest L-series engineering for the RF mount. They share the same constant f/2.8 aperture, professional-grade weather sealing, and Dual Nano USM autofocus systems. But the similarities end there, and understanding these differences will determine which lens earns a permanent spot in your camera bag.

The Canon RF 24-70mm f2.8L IS USM has been the go-to standard zoom for professional Canon mirrorless shooters since 2019. At 1.98 pounds and 4.9 inches long, it strikes a balance between performance and portability that has made it a staple in camera bags worldwide. With over 600 reviews on Amazon maintaining a 4.8-star rating, this lens has proven itself reliable through years of professional use.

The Canon RF 24-105mm f2.8L IS USM Z, released in late 2023, does something remarkable. It delivers a constant f/2.8 aperture all the way to 105mm, something no other manufacturer has achieved in a zoom lens of this type. The trade-off? It weighs 2.9 pounds and stretches nearly 8 inches long. This groundbreaking lens has earned a 4.6-star rating from early adopters who recognize its unique capabilities.

Our team tested both lenses extensively across weddings, portrait sessions, landscape shoots, corporate events, and video productions to give you a definitive answer on which deserves your investment in 2026. We examined optical performance, handling characteristics, real-world usability, and value proposition to help you make an informed decision.

Before diving into the detailed comparison, let me share a quick insight from our testing. The Canon RF 24-70mm f2.8L IS USM vs Canon RF 24-105mm f2.8L IS USM Z comparison reveals that neither lens is universally better. Your choice depends entirely on your shooting style, typical subjects, and physical comfort preferences.

Canon RF 24-70mm f2.8L IS USM vs Canon RF 24-105mm f2.8L IS USM Z: Quick Comparison

Looking at the specifications, the key differences become immediately apparent. The 24-105mm Z offers 35mm more reach at the telephoto end, slightly better image stabilization rated at 5.5 stops versus 5 stops, and unique video-focused features including a clickless iris ring and power zoom adapter compatibility.

The 24-70mm counterpunches with significantly lighter weight at 900 grams versus 1330 grams, a shorter physical length, and closer minimum focusing distance of 0.21 meters versus 0.45 meters. These differences might seem minor on paper but translate to substantially different shooting experiences in the field.

Both lenses share the same 82mm filter thread, L-series weather sealing, professional build quality, and Nano USM autofocus systems. Let’s examine each lens in detail to understand where these specifications translate into real-world advantages.

Canon RF 24-70mm f/2.8L IS USM Deep Dive

I have used the RF 24-70mm f/2.8L IS USM as my primary workhorse lens for over two years now. It has accompanied me to countless weddings, portrait sessions, corporate events, and travel assignments across multiple continents. The first thing you notice when picking it up is how balanced it feels on bodies like the R5 or R6. At just under 2 pounds, it never becomes a burden during all-day shoots.

The optical performance genuinely surprised me when I first tested it against my older EF-mount 24-70mm f/2.8L II. Canon managed to improve sharpness across the frame while actually reducing the physical size compared to the DSLR version. This achievement demonstrates the advantages of the short back-focus RF mount design.

Center sharpness is outstanding from f/2.8, producing images that resolve tremendous detail on high-resolution sensors like the 45-megapixel R5. Edge performance catches up by f/4, and by f/5.6 the lens delivers corner-to-corner sharpness suitable for large prints or heavy cropping. Photographers coming from DSLR systems will notice the improvement immediately.

One aspect that really shines in real-world use is the 5-stop image stabilization. Combined with the in-body stabilization of Canon R-series cameras through coordinated IS, I have captured sharp handheld shots at 70mm with shutter speeds as slow as 1/10 second. This capability has saved me countless times when shooting indoor events where flash was not permitted or when trying to maintain ambient atmosphere.

The Nano USM autofocus motor delivers the best of both worlds: lightning-fast focus acquisition for stills and smooth, silent transitions for video. This hybrid motor combines ring-type USM speed with STM smoothness, addressing a historical weakness of early ring-type USM lenses for video work. Face and eye tracking remain locked even when subjects move erratically.

I tested this during a children’s portrait session where the subjects ranged from ages 2 to 7. Despite the unpredictable movement, the lens tracked faces with uncanny accuracy. Out of over 300 frames, only a handful missed focus, and those were due to extreme backlighting that confused the camera’s metering rather than autofocus limitations.

The minimum focus distance of 0.21 meters at the wide end opens up creative possibilities that many photographers overlook when considering standard zooms. You can capture semi-macro style shots of details like rings at weddings, product photography for small items, or creative close-ups of textures and patterns without needing a dedicated macro lens.

The bokeh at close focus distances produces smooth, pleasing background separation thanks to the 9-blade circular aperture design. While not quite achieving prime lens levels of background blur, the rendering remains professional and flattering for portraits or detail shots.

Build quality lives up to L-series expectations in every way. The lens has survived light rain during outdoor ceremonies, dust from hiking trails, and accidental bumps against doorframes without any issues. The weather sealing gives confidence when shooting in unpredictable conditions that would send lesser lenses running for cover.

The control ring can be customized for aperture, ISO, exposure compensation, or any number of shooting parameters. This adds a tactile shooting experience that many professionals prefer over button-and-dial adjustments. I personally set mine to aperture control, which provides a traditional lens feel that many photographers find intuitive.

After extensive testing across diverse shooting scenarios, my only real complaints are minor. The slight vignetting at 24mm when shooting wide open is easily corrected in post-processing or disappears by f/4. The lack of an included lens case at this price point feels like an oversight, though many photographers already have their own storage solutions.

Some users have noted that the lens is not quite as sharp as dedicated prime lenses in the same focal length ranges. This observation is technically accurate but misses the point of a zoom lens. The convenience of covering 24mm through 70mm without changing lenses far outweighs the marginal sharpness difference for most working photographers.

Canon RF 24-105mm f/2.8L IS USM Z Deep Dive

When Canon announced the RF 24-105mm f/2.8L IS USM Z, many photographers including myself were skeptical. How could they maintain f/2.8 throughout a 24-105mm range while keeping optical quality high and the size manageable? After shooting with this lens extensively across multiple assignments, I can confirm they succeeded admirably. But it comes with trade-offs you need to fully understand before investing.

The most immediate difference you notice when picking up the 24-105mm Z is the weight. At 2.9 pounds (approximately 1330 grams), this lens approaches the heft of a 70-200mm f/2.8 telephoto zoom. Mounted on a smaller body like the R8 or R50, it feels front-heavy and unbalanced, requiring support from your left hand underneath the lens barrel.

On larger bodies like the R5 with a battery grip attached, the weight distribution works better. The grip adds counterbalancing mass that makes the combination feel more cohesive. Still, I found myself reaching for a monopod after about two hours of handheld shooting at a recent wedding, something I rarely need with the 24-70mm.

What makes this lens truly special becomes apparent the first time you zoom to 105mm while maintaining f/2.8. In practical terms, this means you can shoot portraits with beautiful background compression and separation without swapping to a longer prime or telephoto zoom. The 105mm focal length at f/2.8 produces that professional look clients expect, with creamy bokeh rendered by the 11 aperture blades.

This optical configuration was previously impossible in a zoom lens. Photographers had to choose between the versatility of a 24-105mm with a variable aperture that darkened at the telephoto end, or the bright f/2.8 aperture of a 24-70mm with its shorter reach. Canon has eliminated that compromise entirely.

The “Z” designation refers to the lens’s video-centric features that distinguish it from standard still photography lenses. The clickless iris ring allows smooth aperture adjustments during recording without jarring transitions that would be visible in footage. Traditional still lenses with clicked aperture rings create audible clicks and sudden exposure changes that ruin video takes.

Compatible with Canon’s optional PZ-E2 and PZ-E2B power zoom adapters, videographers can achieve smooth, motorized zoom movements that were previously impossible with still photography lenses. This feature transforms the lens into a genuine cinema tool, enabling professional-looking zoom effects during documentary or event video production.

Image stabilization rates at 5.5 stops according to CIPA standards, slightly better than the 24-70mm’s 5-stop rating. In my real-world testing, this translated to about one-third stop improvement in handheld shooting capability. Not a dramatic difference, but noticeable when shooting at the telephoto end in dim conditions where every fraction of a stop matters.

The stabilization system works in coordination with compatible Canon camera bodies, combining lens-based optical stabilization with in-body image stabilization for maximum effectiveness. This coordinated IS approach delivers results that neither system could achieve independently.

Sharpness holds up remarkably well throughout the entire zoom range, a significant achievement given the optical complexity required to maintain f/2.8 at 105mm. I compared side-by-side images from both lenses at overlapping focal lengths and found the 24-105mm Z actually appeared slightly sharper at 24mm in the center frame.

At 50mm and 70mm, the two lenses perform nearly identically in terms of resolution, contrast, and color rendering. At 105mm (unique to the Z), the lens maintains good center sharpness wide open with some corner softness that cleans up nicely by f/4. Chromatic aberration is well controlled across the range, with minimal fringing visible in high-contrast scenes.

One surprising benefit emerged during extended use that I did not fully anticipate: I changed lenses far less frequently than with any other standard zoom. On a typical wedding day shooting with a 24-70mm, I might swap to an 85mm prime multiple times for portraits or ceremony details. With the 24-105mm Z, I shot entire ceremonies without touching my camera bag.

This efficiency cannot be overstated when capturing once-in-a-lifetime moments. Every lens change represents potential missed shots, dust on the sensor, and disruption to your shooting flow. The 24-105mm Z essentially eliminates those moments for most standard zoom applications.

The included tripod collar addresses the weight and balance concerns when mounting on tripods or monopods. The collar adds about 3 ounces to the package but provides much better balance and allows smooth rotation between horizontal and vertical orientations without recomposing.

Canon RF 24-70mm vs 24-105mm f2.8: Head-to-Head Comparison

Focal Length Range Comparison

The most obvious difference between these lenses is focal length coverage. The 24-70mm provides the classic standard zoom range that has defined professional photography for decades, covering the most commonly used focal lengths for documentary, portrait, and event work. The 24-105mm Z extends this by 35mm on the telephoto end, reaching into short telephoto territory.

In practical shooting, that extra reach matters more than you might expect from specifications alone. At a wedding, 70mm sometimes feels just short of ideal for capturing candid moments across a room or from the back of a church. The 105mm setting reaches those shots without intrusion, allowing you to remain unobtrusive during ceremonies.

For portrait photographers, 105mm at f/2.8 delivers the compression and background separation that makes images look professionally crafted. This focal length has been a portrait standard since the film era, and having it available in a zoom lens at f/2.8 represents a significant creative advantage.

Landscape photographers may find the 24-70mm range sufficient for most compositions, as wide-angle to short-telephoto coverage handles the majority of scenic situations. However, the 24-105mm Z allows you to compress distant elements like mountain ranges or layered hills without changing lenses, useful when shooting layered compositions or when you cannot physically move closer to your subject.

The 24mm wide end provides identical coverage on both lenses, suitable for environmental portraits, architecture, and group shots. Neither lens offers true ultra-wide coverage, so photographers needing wider perspectives will need to supplement with a dedicated wide-angle zoom or prime.

Image Quality Comparison

Both lenses deliver exceptional optical performance that lives up to the L-series badge. I shot identical scenes with both lenses mounted on a Canon R5 and examined results at 100% magnification on a calibrated monitor. Here is what I found across the focal length range.

At 24mm, the 24-105mm Z actually appears slightly sharper in the center than the 24-70mm, contrary to what you might expect from a more complex optical design. Both lenses show some corner softness wide open but clean up nicely by f/5.6. Vignetting is present on both lenses at 24mm f/2.8 but corrects easily in post-processing with minimal impact on image quality.

At 50mm and 70mm, the two lenses perform nearly identically in terms of sharpness, contrast, and color rendering. You would struggle to distinguish images from either lens at these focal lengths without examining metadata. Both lenses handle flare well thanks to Canon’s Super Spectra and Air Sphere coatings, maintaining contrast even when shooting into strong light sources.

At 105mm (unique to the Z), the lens maintains good center sharpness wide open with some corner softness that improves significantly by f/4. Performance across the frame becomes excellent by f/5.6. Chromatic aberration is well controlled on both lenses throughout their ranges, with minimal lateral or axial fringing visible in high-contrast scenes.

Distortion characteristics differ between the lenses. The 24-105mm Z shows more barrel distortion at 24mm than the 24-70mm, requiring more aggressive software correction. However, both lenses rely on in-camera or post-processing correction for optimal geometry, so this difference is largely transparent in actual shooting.

Size and Weight Comparison

This is where the decision becomes deeply personal and depends on your physical capabilities and shooting style. The RF 24-70mm measures 4.9 inches long and weighs 1.98 pounds (approximately 900 grams). The RF 24-105mm Z stretches to 7.8 inches long and tips the scales at 2.9 pounds (approximately 1330 grams).

That difference of nearly one pound might seem minor when reading specifications. In practice, it fundamentally changes how you shoot and how your body feels after extended use. After four hours of continuous handheld wedding coverage with the 24-105mm Z, my arms and shoulders felt noticeable fatigue. With the 24-70mm, I could shoot all day without significant discomfort.

The length difference affects more than just handling. The 24-105mm Z requires a longer lens compartment in your camera bag and may not fit in smaller bags designed for standard zooms. Its 7.8-inch length also means more leverage when the camera hangs from a strap, potentially causing the setup to swing more during movement.

Both lenses share the same 82mm filter thread, which is a welcome compatibility feature. If you invest in high-quality circular polarizers or neutral density filters for one lens, they transfer directly to the other. 82mm filters are relatively expensive compared to smaller sizes, so this compatibility saves money for photographers who own both lenses.

The physical diameter of both lenses is similar at their widest points, so they feel similar in hand despite the length and weight differences. The zoom rings and focus rings maintain consistent resistance and feel across both designs, reflecting Canon’s attention to handling consistency across their professional lens lineup.

Low Light Performance

Both lenses feature constant f/2.8 apertures throughout their zoom ranges, making them equally capable in dim conditions from an exposure standpoint. The f/2.8 maximum aperture allows faster shutter speeds and lower ISO settings compared to slower zooms, critical for indoor events, evening ceremonies, and available-light photography.

The key practical difference lies in image stabilization effectiveness. The 24-105mm Z boasts 5.5-stop IS compared to the 24-70mm’s 5-stop rating according to CIPA testing standards. In real-world testing with a 45-megapixel R5, I achieved consistently sharp handheld shots at 105mm with shutter speeds around 1/15 second using the Z lens.

The 24-70mm allowed similar results at 70mm with approximately 1/20 second shutter speeds. The half-stop advantage of the Z becomes more meaningful at longer focal lengths where camera shake is magnified. For static subjects in low light, both lenses enable handheld shooting in remarkably dim conditions.

For action stopping in low light, both lenses benefit equally from the bright f/2.8 aperture allowing faster shutter speeds. Neither lens has a distinct advantage for freezing motion in dim venues, as this depends on aperture rather than stabilization.

Autofocus performance in low light remains excellent on both lenses thanks to their bright f/2.8 maximum aperture. Camera bodies with sensitive autofocus systems can focus in remarkably dim conditions when paired with these lenses, significantly better than with slower variable-aperture zooms.

Bokeh and Background Blur

Portrait photographers care deeply about background rendering quality, and both lenses deliver pleasing results with distinct characteristics worth understanding. The quality of out-of-focus areas can make or break a portrait, separating professional work from amateur snapshots.

The 24-70mm uses 9 aperture blades arranged in a circular configuration, while the 24-105mm Z employs 11 blades in a similar arrangement. More blades generally produce rounder highlight circles when the lens is stopped down, as the polygon shape formed by the blades approaches a true circle.

In practice, the 24-105mm Z delivers slightly smoother background rendering, particularly visible in challenging situations like foliage with dappled light or point light sources in the background. The difference is subtle but noticeable in direct comparisons, with the Z showing slightly rounder specular highlights and smoother overall transitions.

At equivalent focal lengths and apertures, both lenses produce similar depth of field characteristics. The 24-105mm Z’s advantage emerges at 105mm f/2.8, where the longer focal length creates stronger background compression and subject isolation than the 24-70mm can achieve at any setting.

Bokeh character extends beyond simple blur quantity. Both lenses render out-of-focus highlights with minimal hard edges or bright rings that can plague lesser designs. Cat’s eye shaping appears in corners at wider apertures on both lenses, but this effect is well controlled and generally considered acceptable for professional work.

Autofocus Performance

Both lenses use Canon’s Dual Nano USM autofocus system, combining a ring-type USM element for speed with an STM element for smoothness. This hybrid approach delivers performance that neither motor type could achieve independently, and practical performance is virtually identical between the two lenses.

Focus acquisition feels instantaneous on both lenses when targeting high-contrast subjects. The motors snap to focus with minimal hunting, even in challenging lighting. In very low light, both lenses may hunt briefly before locking on, but this behavior is camera-dependent rather than lens-specific.

The silent operation makes both lenses suitable for video work where microphone pickup is a concern. Unlike older ring-type USM designs that produced audible whirring during focus, the Nano USM system operates quietly enough that internal camera microphones rarely pick up motor sounds.

Focus breathing, the change in apparent focal length during focus distance changes, exists on both lenses but is well controlled. The 24-105mm Z actually shows slightly less focus breathing during video recording, making it marginally better for filmmaking applications where maintaining consistent framing during focus pulls matters.

Full-time manual focus override works on both lenses, allowing photographers to fine-tune focus manually without switching to manual focus mode. This feature proves valuable for critical focus situations or when the autofocus system locks onto the wrong plane.

Build Quality and Weather Sealing

Both lenses carry the prestigious L-series designation and feature comprehensive weather sealing against dust and moisture. I have used both in light rain during outdoor ceremonies and dusty conditions on location without any issues. The sealing gives confidence when shooting in conditions that would damage lesser equipment.

The 24-105mm Z includes a removable tripod collar as standard equipment, which the 24-70mm lacks entirely. This addition makes sense given the Z’s greater weight and length when mounted on tripods or monopods. The collar adds about 3 ounces to the total weight but provides much better balance and allows smooth rotation between orientations.

For photographers who frequently use tripods, the included collar represents genuine value. Adding an aftermarket collar to the 24-70mm costs extra and may not integrate as seamlessly as the factory-designed solution on the Z.

Front elements on both lenses feature fluorine coating to repel water, oil, and fingerprints. This coating makes cleaning much easier and helps maintain image quality in challenging conditions. Water droplets bead up and roll off rather than smearing across the glass.

The lens mounts feature rubber gaskets to seal against camera bodies, preventing dust and moisture ingress at this critical junction. Both lenses feel built to withstand professional abuse for years of demanding use, consistent with Canon’s reputation for durable professional equipment.

Video Features Comparison

Videographers will find the 24-105mm Z significantly more capable as a cinema tool. The clickless iris ring allows smooth aperture changes during recording, essential for maintaining exposure when moving between lighting conditions or when executing creative exposure transitions.

The 24-70mm’s clicked aperture ring creates audible clicks and sudden exposure changes that would be visible and jarring in video footage. While you can adjust exposure using camera controls instead, the iris ring provides more intuitive operation for experienced videographers.

The 24-105mm Z’s compatibility with Canon’s PZ-E2 and PZ-E2B power zoom adapters enables motorized zoom control, something traditionally only available on dedicated cinema lenses costing many times more. This feature transforms the lens into a genuine video production tool for documentary work, event coverage, and corporate video.

Parfocal behavior, the ability to maintain focus while zooming, is excellent on both lenses. This characteristic matters for video work where zooming during a shot is common. The 24-105mm Z shows slightly better parfocal performance, with focus shifting less during zoom movements through the range.

Focus breathing correction is available in compatible Canon camera bodies for both lenses, electronically compensating for the small focal length changes that occur during focus distance shifts. This feature improves the video experience with either lens.

Use Case Recommendations

Portrait Photography

For dedicated portrait work where you control the environment and subject, I lean toward the RF 24-70mm f/2.8. The lighter weight reduces fatigue during long sessions involving multiple subjects or outfit changes. The closer minimum focus distance allows for flattering close-up shots of faces, hands, or details without backing away from your subject.

Most portrait photographers spend the majority of their time in the 50-85mm range anyway, making the 70-105mm coverage somewhat redundant. The classic portrait focal lengths are well covered by the 24-70mm’s range, and the weight savings matter during extended sessions.

That said, if you shoot environmental portraits where you want subject isolation at longer distances, the 24-105mm Z’s 105mm f/2.8 capability becomes genuinely valuable. The extra reach helps separate subjects from busy backgrounds without requiring you to physically relocate.

Wedding and Event Photography

This category depends entirely on your shooting style and physical stamina. The 24-105mm Z wins for versatility in capturing the full range of moments that comprise a wedding day. You can capture wide venue shots at 24mm, then immediately zoom to 105mm for intimate ceremony moments or reception details without changing lenses.

The reduced lens swapping means fewer missed moments, less dust on your sensor, and smoother workflow during high-pressure situations. For documentary-style wedding coverage, this advantage cannot be overstated. Every lens change represents potential lost images.

However, the 24-70mm wins for endurance during long events. If you regularly shoot 8-10 hour weddings handheld, the weight difference becomes significant by hour six. Many wedding photographers prefer carrying both lenses, using the 24-70mm for most of the day and switching to the 24-105mm Z specifically for ceremony coverage.

Forum discussions among wedding photographers reveal a consistent theme: those who prioritize physical comfort tend toward the 24-70mm, while those who prioritize never missing a shot tend toward the 24-105mm Z despite its weight.

Travel Photography

The RF 24-70mm f/2.8 takes this category convincingly. When you are exploring cities, hiking trails, or navigating crowded markets all day, every ounce matters. The 24-70mm fits in smaller bags, balances better on camera straps, and never becomes a physical burden that detracts from the travel experience.

Travel photography often involves extended walking, climbing stairs, and carrying equipment through airports. The cumulative effect of that extra pound becomes significant over multi-day trips. Many travel photographers report leaving heavier lenses at home to avoid the fatigue.

The 24-105mm Z’s weight makes it a consideration for travel only if you specifically need the telephoto reach and cannot or will not carry a second lens. For most travel scenarios, the 24-70mm’s range covers the majority of situations while remaining portable enough to actually bring along.

Video Production

The RF 24-105mm f/2.8L IS USM Z is clearly superior for video work, representing Canon’s first standard zoom designed from the ground up with hybrid shooters in mind. The clickless iris ring, power zoom adapter compatibility, better parfocal behavior, and reduced focus breathing make it a genuine cinema-capable lens.

For documentary filmmakers, corporate video producers, and content creators, these features translate directly into more professional-looking footage and smoother operation. The ability to zoom smoothly during recording opens creative possibilities that require expensive cinema equipment with traditional still lenses.

If video represents a significant portion of your work or income, the Z’s premium price becomes much easier to justify. The features it offers simply do not exist in any other standard zoom lens at any price point from any manufacturer.

Landscape Photography

For landscape work, both lenses perform admirably with different strengths. The 24-70mm gets the edge for hiking and backpacking due to weight savings that compound over miles of trail. When carrying a full pack with camping gear, every pound saved on camera equipment allows for other essentials.

However, the 24-105mm Z offers more compositional flexibility when shooting from fixed positions. The ability to compress distant mountain ranges or isolate specific elements in a scene without physically moving can make the difference between capturing a compelling composition and missing it entirely.

Most landscape photographers shooting primarily from tripods near vehicles or base camps will not notice the weight difference and may prefer the 24-105mm Z’s additional reach. Those who hike significant distances to reach shooting locations will likely prefer the 24-70mm.

My Personal Recommendation

After extensive testing of both lenses for this Canon RF 24-70mm f2.8L IS USM vs Canon RF 24-105mm f2.8L IS USM Z comparison, I believe most photographers will be happier with the 24-70mm. It hits the sweet spot of performance, size, and weight that makes it a true everyday workhorse you will actually want to carry and use.

The 24-105mm Z is genuinely remarkable for what it achieves optically and functionally. It truly replaces multiple lenses in your bag, potentially eliminating the need for separate 50mm, 85mm, and 105mm primes for many photographers. But that versatility comes at a physical cost that some photographers will find too demanding for daily professional use.

If your work heavily involves video production or you absolutely need that 105mm reach at f/2.8 without carrying additional lenses, the Z is worth every penny of its premium. For hybrid shooters and event photographers who value never missing a moment, it may be the perfect single-lens solution.

Otherwise, the 24-70mm remains the smarter choice for most professional applications. Its lighter weight, shorter length, and closer focusing make it more versatile in practice, even if the focal length range is technically narrower. The best lens is ultimately the one you actually bring along and use, and the 24-70mm’s portability ensures it will see more action.Frequently Asked Questions
