The Canon EF 16 to 35-millimeter f/2.8L III UltraSonic Motor Lens is an ultra-wide-angle zoom lens that is used both by professionals and enthusiasts alike. Regardless of whether you are shooting still photographs or recording videos, they will be captured with edge-to-edge sharpness every time in good lighting conditions. Some vignette corner shading can occur in dark conditions when the lens is being used wide open. However, the EF 16 to 35-millimeter lens can be used in a variety of conditions from cloudy days to sunny days and still produce clear images.

Fans of image stabilization will appreciate the sharp shots this lens will deliver with the EF 16 to 35-millimeter's image stabilizer turned on, and even the crisp shots it can produce with the image stabilizer turned off. Even using this lens handheld will produce sharp images that normally would just be seen with a tripod. The improved peripheral illumination in the lens helps to reduce distortion at extremely wide angles that occurred in earlier versions of the EF 16 to 35-millimeter lens. It is recommended that this lens be used with a single-lens reflex camera that has a full-frame sensor, but it is not a requirement. The Canon EF 16 to 35-millimeter f/2.8L III UltraSonic Motor Lens is suggested for anyone who wants to produce high-resolution photos and videos, whether it's for their job or just for fun.
