Canon Canon L Canon EF 24-105mm f/4 L is USM Lens for Canon EOS Review

The Canon EF 24-105mm f/4 L IS USM is a versatile, well-built standard zoom for Canon DSLRs with fantastic autofocus and stabilization. Its optical performance is showing its age, with soft corners and mediocre bokeh. At $786, it's a tough sell unless you specifically need its ruggedness and zoom range on an EF-mount camera.

If you're shooting with a Canon DSLR and want one lens that can handle most situations, the Canon EF 24-105mm f/4 L IS USM is probably on your list. It's a classic 'walk-around' zoom for full-frame cameras, covering a useful range from wide-angle to short telephoto. The constant f/4 aperture and built-in image stabilization make it a solid all-rounder for everything from travel to events, though at around $786, it's a serious investment. People often search for a 'do-it-all lens for Canon' or a '24-105mm review,' and this is the original L-series version that's been around for years.

Our database puts this lens in the 99th percentile for autofocus speed and accuracy, thanks to that ring-type USM motor. It's fast and quiet, which is great for both stills and video. The image stabilization is rated in the 87th percentile, giving you about three stops of shake correction for handheld shots. Where it shows its age is in optical performance, landing in just the 35th percentile. You'll get some softness in the corners, especially at wider apertures, and chromatic aberration can pop up in high-contrast scenes. It's sharp enough in the center for most work, but don't expect modern lens perfection.

At $786, this lens isn't cheap, and its value really depends on your camera. If you're on a modern Canon DSLR and need a single, durable, all-purpose zoom with pro-grade autofocus and sealing, it's still a contender. But that money could also get you a sharper prime lens or a newer third-party zoom with better optics. You're paying a premium for the L-series build and the Canon badge on a design that's over a decade old.

This lens sits in a weird spot. Compared to the newer Canon RF 24-105mm f/4 L for mirrorless, it's optically inferior and requires an adapter for RF cameras, so that's not a fair fight. Against something like the Tamron 24-70mm f/2.8 G2 for Canon EF, you lose the extra reach to 105mm but gain a full stop of light (f/2.8) and significantly sharper optics. For someone who doesn't need weather sealing, the Canon EF 24-105mm f/3.5-5.6 IS STM is much lighter and cheaper, though with a variable, slower aperture. The Viltrox and Meike primes mentioned as competitors are completely different beasts—they're much faster (f/1.4-f/1.7) and sharper for portraits, but you lose the zoom versatility.

Skip this lens if you're a pixel-peeper who demands corner-to-corner sharpness, a portrait photographer who needs creamy bokeh (look at a 50mm or 85mm f/1.8 instead), or a low-light shooter who needs faster than f/4. Also, if you're planning to move to a Canon mirrorless system soon, investing in EF glass might not be the best long-term plan. Consider the RF 24-105mm f/4 L or adapting a sharper third-party EF zoom instead.

Should you buy this lens? Only with clear conditions. If you shoot a Canon DSLR (like a 5D or 6D series) and need a single, tough, go-anywhere zoom for travel, events, or general photography where absolute corner-to-corner sharpness isn't critical, it can still work. The autofocus and stabilization are excellent. But if you're starting fresh, care about optical quality, shoot in low light often, or are considering moving to mirrorless, there are better options. Think of it as a reliable workhorse, not a precision instrument.
