What is the Canon EF 28-105mm f/4-5.6 USM?
The Canon EF 28-105mm f/4-5.6 USM is a versatile zoom lens designed for Canon EOS cameras. It is part of Canon’s EF lens lineup, which is compatible with both full-frame and APS-C sensor cameras. This lens offers a focal length range from 28mm to 105mm, making it suitable for a variety of photography genres, including landscapes, portraits, and everyday snapshots.
The “f/4-5.6” aperture range signifies the lens’s maximum aperture, which can vary depending on the zoom setting. At 28mm, the lens has a maximum aperture of f/4, while at 105mm, the maximum aperture is f/5.6.

The USM technology also enables full-time manual focus override, allowing users to make fine adjustments manually without switching to manual focus mode.
The lens construction consists of 15 elements in 12 groups, including a single aspherical lens element. This design helps minimize various optical aberrations, resulting in improved image quality and sharpness throughout the zoom range. Additionally, Canon’s Super Spectra Coating is applied to reduce flare and ghosting, ensuring accurate colors and high contrast in photos.
