Overview

THIS IS A USED ITEM
IMAGES ARE FOR ILLUSTRATIVE PURPOSES ONLY
Condition: Good

The Canon 17–40mm F/4 L Lens is suitable for amateur photographers. It is compatible with both 35mm film and Canon APS-C sensor cameras that have the EF mount. Its lens design involves 12 optical elements in 9 groups, which include 3 aspherical elements and 1 super ultra-dispersion element to reduce chromatic and spherical aberrations. The lens performs quick and silent autofocus with its ultrasonic AF motor. Moreover, its internal focusing and zooming do not alter the overall size of the lens. The circular seven-blade diaphragm offers a pleasing bokeh in the background. This Canon EF-mount L-series lens has a dust- and moisture-resistant design that makes it easy to use it in adverse weather conditions.
