Review

The Canon EF 24-85mm f/3.5-4.5 USM is a versatile standard zoom lens that has been designed to cater to a variety of shooting scenarios. With a focal length range that spans from wide-angle to short telephoto, this lens is an excellent choice for photographers who need flexibility without the burden of carrying multiple lenses.

Build Quality and Design

The build quality of the Canon EF 24-85mm f/3.5-4.5 USM is satisfactory, featuring a plastic barrel that keeps the weight down, making it relatively lightweight for a standard zoom lens. The matte finish provides a professional look but may be prone to scuffs and scratches. The lens features a rotating zoom mechanism, which allows for easy adjustment of focal lengths. It also comes with a petal-shaped lens hood which helps to reduce lens flare during bright conditions.

Optical Performance

When it comes to optical performance, the Canon EF 24-85mm delivers good sharpness across its zoom range. The center sharpness is impressive even at the widest aperture settings, although sharpness could slightly decrease at the extreme corners—especially at wider focal lengths. Chromatic aberration is well controlled due to the lens's multi-coated elements, although some color fringing can still be noticed against high-contrast edges. This lens also fares reasonably well in low light conditions, thanks to its maximum aperture of f/3.5-4.5, but it is not as fast as some competitors.

Autofocus and Usability

The USM (Ultrasonic Motor) technology employed in this lens ensures fast and quiet autofocus performance. This makes it an ideal choice for both still photography and videography where noise can be an issue. Manual focus override is also smooth and precise, offering photographers better control over their settings. The 67mm filter thread allows for easy attachment of filters, which is a plus for enthusiasts looking to experiment with various effects.

Compatibility and Use Cases

This lens is compatible with Canon's full-frame and APS-C DSLR cameras, making it a versatile option for both amateur and professional photographers. It is well-suited for landscapes, portraits, and everyday photography, providing a comfortable range for capturing both wide scenes and tighter compositions. However, for more serious portrait work, a dedicated prime lens may yield better results.

While it has its shortcomings, such as softer corners and a less-than-ideal maximum aperture for low-light conditions, its good optical performance, fast autofocus, and reasonable price point make it an attractive option for hobbyists and photographers alike. Whether you're capturing landscapes or casual portraits, this lens is well-equipped to handle a variety of shooting situations.
