It is great for landscapes, architecture, interiors, real estate, events, travel, creative wide-angle shots, and low-light situations where you need a wider field of view. The USM autofocus is fast and quiet. Included: * Canon EF 16-35mm f/2.8L II USM lens * B+W UV filter included Used but in good working condition.
