Canon EF 24-70mm F/2.8 L USM vs 24-105 Comparison
Zoom Range and Focal Lengths
The 24-70mm covers a standard zoom range, from wide-angle to short telephoto. It’s perfect for landscapes, architecture, or portraits. I love its versatility for everyday shooting. The 24-105mm extends to 105mm, great for tighter shots like headshots or distant landscapes.
That extra reach is handy when you can’t get closer, like in wildlife or street photography. Both start at 24mm, offering a wide field of view. The 24-105mm’s longer range makes it more flexible for varied scenarios.

Aperture and Low-Light Performance
The biggest difference is the aperture. The 24-70mm boasts a constant f/2.8, letting in twice as much light as the 24-105mm’s f/4. This is a game-changer in low-light, like indoor events or sunset shoots. I can use faster shutter speeds, reducing camera shake.
The f/2.8 also creates a shallower depth of field, ideal for isolating subjects in portraits. The 24-105mm performs well at f/4, but I often need higher ISO in dim conditions. Its stabilization helps, which we’ll cover next.
Image Quality and Sharpness
Both lenses deliver exceptional image quality, as expected from Canon’s L-series. The 24-70mm is slightly sharper, especially at f/2.8. I’ve used it for critical shots like product photography, and it’s razor-sharp. Its optics include one ultra-low dispersion element and two aspherical elements.
The 24-105mm is also very sharp, though slightly less so at the zoom extremes. In real-world use, the difference is negligible unless you’re printing large. Both handle flare and ghosting well, thanks to advanced coatings.
Image Stabilization
The 24-105mm shines with image stabilization, offering up to three stops. This is a lifesaver for handheld video or low-light stills. I’ve shot at 1/30s at 70mm and got sharp images. It’s ideal for dynamic situations.
The 24-70mm lacks stabilization, so I rely on faster shutter speeds. Its f/2.8 aperture helps, but I miss IS in video or shaky conditions. For videographers, the 24-105mm’s stabilization is a clear win.
