Canon EOS R5 C 5077C026 24-105mm

The Canon RF 24-105mm f/2.8 is a one-of-a-kind workhorse that delivers best-in-class sharpness and stabilization in a heavy, expensive package. It's a dream for event shooters who want to ditch lens swaps without sacrificing low-light performance. The price is steep around $2,980, but it can replace multiple f/2.8 zooms in your bag. If you don't absolutely need that constant fast aperture, the lighter and cheaper RF 24-105mm f/4 is the smarter pick.

Sharpness is this lens's party trick, and it's a good one. In our database, its optical performance is basically best-in-class, sitting in the 99th percentile. That translates to images that are crisp across the frame, even wide open at f/2.8. The combination of three aspherical elements and four ED elements does some heavy lifting to keep chromatic aberration and distortion in check. You can shoot a wedding ceremony at 105mm and f/2.8 and count the eyelashes, then pull back to 24mm for a group shot without missing a beat. The Nano USM autofocus is fast, nearly silent, and accurate, landing well above average in our rankings. It's the kind of AF that just gets out of your way.

Stabilization is another standout. The lens alone gives you 5.5 stops of shake correction, and when you pair it with a camera that has IBIS, you get up to 8 stops of coordinated IS. That's leading in its class and a real-world game changer for handheld video or shooting in dimly lit venues. The 11-blade aperture is nice on paper, but our data shows the bokeh quality is actually pretty middle-of-the-pack. It's pleasant and gets the job done, but don't expect the buttery, melt-away background of a dedicated f/1.4 prime. The close-focusing ability is also just okay, with a 0.29x magnification that's underwhelming if you like to dabble in near-macro details. It's not a weak spot, exactly, but it's not a reason to buy this lens.

The most obvious competitor is Canon's own RF 24-105mm f/4 L IS USM. It's smaller, lighter, and significantly cheaper, but you lose a full stop of light. For landscape shooters or anyone working on a tripod, the f/4 version makes a lot more sense. But for wedding and event photographers who live at f/2.8, this new Z lens is in a different league. The other elephant in the room is a two-lens combo like the RF 24-70mm f/2.8 and RF 70-200mm f/2.8. You'll get better bokeh and a longer reach, but you'll also be carrying more weight overall and constantly swapping lenses. This 24-105mm is the 'one lens to rule them all' for a specific kind of fast-paced shooting.

Looking outside the Canon ecosystem, the Panasonic LUMIX S S-R28200 is a competitor in spirit, offering a huge range, but it has a slow, variable aperture that can't touch this lens's low-light performance. The Tamron 17-70mm f/2.8 is a great APS-C option, but it's not full-frame and doesn't have the same reach. The Sigma 16-300mm is a superzoom, a totally different beast built for ultimate range at the expense of image quality and speed. This Canon is in a unique spot. It's a no-compromise, fast standard zoom that stretches further than any other, and the trade-off is purely its size and cost.

Let's talk money, because this lens costs a lot of it. The price range across vendors is all over the map, with a spread of over $1.4 million, which is clearly some third-party seller nonsense on the high end. The real street price you should be looking for hovers around the $2,980 mark. For that, you're getting a lens that can realistically replace a 24-70mm f/2.8 and a 70-200mm f/2.8 for a lot of event work, which together would cost you significantly more and weigh even more in your bag. It's not cheap, but the value proposition is strong if you actually leverage its full range.

Compared to buying multiple fast zooms, this is a consolidation play. You're paying a premium for the convenience and the unique f/2.8 range, not just the glass. If you're a working pro who bills for your time, the reduction in lens swaps alone can justify the cost over a busy season. For enthusiasts, it's a harder sell. The optical quality is undeniable, but you have to ask yourself if you truly need that constant f/2.8 out to 105mm, or if the much lighter and cheaper RF 24-105mm f/4 L would do the job just fine.

Canon did something a little wild here. They took the classic 24-105mm workhorse focal range and gave it a constant f/2.8 aperture, which is a first for this zoom range. That means you get the versatility of a standard zoom with the low-light chops and subject separation you'd normally need a bag of primes for. It's built for the RF mount and clearly aimed at working photographers who live in the event, wedding, and photojournalism trenches, but it's also got some serious video tricks up its sleeve. If you've ever juggled a 24-70mm and a 70-200mm at a fast-paced gig, this lens is basically Canon's way of saying 'we hear you.'

But let's address the elephant in the room right away. This thing weighs over 1300 grams, which is heavier than a lot of 70-200mm f/2.8 lenses. It's a chunky piece of glass, and you'll feel it after a long day of shooting. The build quality is solid, but our data puts it in a surprisingly low percentile for its class, which tells you more about the tank-like competition than any real fragility. It's weather-sealed and feels premium, but it's not going to win any lightweight awards. The optical performance, however, is where it really sings. We're talking top-of-the-charts sharpness that lands in the absolute best tier of our database.

This is a lens for a specific kind of shooter. If you need to go from a wide establishing shot to a tight portrait in seconds without swapping glass, and you need that f/2.8 look the whole way, there's nothing else quite like it. It's a statement piece for the RF system, and while the price tag is steep, it's essentially two or three professional lenses in one. For the right person, it's not an expense, it's a workflow revolution.

If you're primarily a landscape or studio photographer who works on a tripod at f/8 or f/11, this lens is overkill. You're paying a huge premium for that f/2.8 aperture and carrying a lot of extra weight for a stop of light you'll rarely use. The Canon RF 24-105mm f/4 L IS USM is optically excellent, much lighter, and costs a fraction of the price. It's the smarter buy for anyone who doesn't live in low light.

Portrait photographers who obsess over bokeh should also look elsewhere. The background blur here is fine, but a dedicated prime like the RF 85mm f/1.2 or even the more affordable RF 85mm f/2 will give you that dreamy subject isolation this zoom can't match. And if you're a run-and-gun vlogger or travel photographer, the sheer size and weight of this lens will get old fast. It's a professional tool built for a specific job, not a casual walkaround lens.

If you're a wedding, event, or documentary photographer who needs to move fast and shoot in unpredictable light, this lens is a revelation. The ability to hold f/2.8 from 24mm all the way to 105mm means you can capture a whole ceremony, from wide venue shots to tight ring exchanges, without ever touching your aperture or swapping glass. The image stabilization is so good you can practically shoot handheld in a cave, and the autofocus is dead reliable. It's a working tool that will pay for itself in missed-shot prevention alone. Pair it with a fast prime for the darkest receptions, and you've got a killer two-lens kit.

For portrait specialists, this probably isn't your lens. The bokeh is just okay, and you'll get more subject isolation and a lighter setup from a dedicated 85mm or 135mm prime. Landscape shooters who stop down to f/8 or f/11 will also find the cheaper, lighter RF 24-105mm f/4 to be the smarter buy. And if you're a hybrid shooter who does a lot of gimbal work, the weight here is a real consideration. It's a fantastic lens, but it's a specialist's tool. Buy it because you need that f/2.8 range, not just because it's the best 24-105mm.
