Canon EF 10-22mm f/3.5-4.5 Usm Lens

The Canon EF 10-22mm f/3.5-4.5 USM is the perfect kit for camera owners who want to get ultra-wide angle focal lengths capability. The lens has excellent build quality and it feels extremely solid and well produced. Yet, it is not too large or heavy for everyday use. The metal lens mount is a testament as to how function can be combined with design.

The lens can deliver fast and quiet auto focus. This is due to the Ring Ultrasonic Motor (USM) feature and a short infinity focus distance of the lens. The minimum focus distance of this lens is 9.5”.

When it comes to its optical quality, the lens really delivers. Images are sharp and have nice details with good color and contrast. Flare and chromatic aberrations are hardly visible. Likewise, barrel distortion isn’t prominent at all. The circular aperture design that the Canon EF 10-22mm f/3.5-4.5 USM Lens has can help produce great out of focus images. This is also partly due to its very deep Depth of Field.

Photographers will love using the Canon EF 10-22mm f/3.5-4.5 USM Lens to create dramatic images. All in all, it’s a great addition to Canon lens lineup.
