Canon 28-300mm f/3.5-5.6 L IS USM EF Mount Lens {77}

Canon's 28-300mm L: one lens for every situation on EOS bodies.

A 28mm wide end gives you genuine environmental coverage, and 300mm brings distant subjects into frame without swapping glass. The f/3.5 maximum aperture at the wide end keeps exposure options open in mixed light, and Canon's L-series optical construction means the image quality holds up across that full 10.7x zoom range. The 77mm filter thread is the same standard used across Canon's most popular L primes and zooms, so your existing filter kit transfers directly.

Built-in Image Stabilization handles camera shake at the long end, which matters when you're shooting handheld at 300mm. USM autofocus is fast and near-silent, a practical advantage for anything that moves or for environments where noise is a concern. On full-frame EOS bodies, you get the full 28-300mm field of view as intended. On APS-C bodies, the effective range shifts to approximately 45-480mm, leaning further into telephoto territory.

This lens is the kind of optic working photographers reach for when carrying multiple bodies or a bag full of primes is not the job. The optical performance and build quality justify carrying it as a primary lens than a compromise.

Who It's For

Travel and documentary photographers who need wide-to-telephoto reach without stopping to change lenses will find the 28-300mm range covers most assignments in a single barrel. Wedding photographers working a ceremony from a fixed position can frame wide establishing shots and pull in to 300mm for candid moments without moving. Photojournalists shooting in unpredictable environments benefit from USM's fast acquisition and the IS system at long focal lengths. Canon EF shooters who have adapted to mirrorless bodies via Canon's EF-EOS R adapter retain full autofocus and stabilization functionality.

FAQ

What's the effective focal range on APS-C Canon bodies?

Approximately 45-480mm due to the 1.6x crop factor. The lens still delivers its full optical performance, but you're working from a longer effective perspective across the range.

Can you use your existing 77mm filters on this lens?

Yes. The 28-300mm shares the same 77mm filter thread as most Canon L primes and zooms, so your current filter kit transfers directly without adapters.

How does autofocus perform at 300mm?

USM autofocus is fast and near-silent. Combined with Image Stabilization, handheld shooting at 300mm is practical for most subjects and lighting conditions.

Is f/3.5 at 28mm enough for mixed-light work?

f/3.5 opens enough exposure options without forcing you to compromise shutter speed or ISO in moderate to bright conditions. The wider end of the range is where you have the most flexibility.

What's the main advantage of 28-300mm over separate lenses?

One lens covers genuine wide environmental coverage through moderate telephoto without swapping glass. It's the working photographer's choice when you need versatility and travel weight matters.

Does Image Stabilization work across the entire zoom range?

Image Stabilization is built-in and active throughout the range, though its benefit becomes most apparent at longer focal lengths where camera shake is more noticeable.
