Wide 94° angle of view on full-frame cameras

Precisely corrected for natural perspective

Aberration effectively suppressed throughout the focus range

Rear-focusing mechanism for fast autofocus response

Circular aperture for attractive defocusing

This rigorously corrected lens gives you a wide angle of view for images that benefit from dramatic perspective with minimum distortion. It’s an ideal choice for covering spread-out scenes that you can’t get far enough way from to cover with a “normal” lens. But there’s more: since it has extended depth of field that can keep everything from 25 centimeters to infinity in crisp focus, you can create exaggerated perspective by including very close and very distant objects in the frame. Close objects will loom large, while distant objects appear to recede markedly into the distance. Meticulous attention has been paid to minimizing flare and internal reflections in this advanced design, with the result that excellent sharpness and contrast are maintained through the image.

An outstanding choice for 35mm full-frame and APS-C format cameras

28 millimeters is an extremely versatile focal length that can be useful in a wide variety of situations on both full frame and APS-C format cameras. On a 35mm full frame format camera, 28mm is wide enough to allow comfortable shooting indoors or on the street without producing forced perspective. On an APS-C format camera 28mm is equivalent to a focal length of 42mm, which is close to “normal” in terms of angle-of-view and perspective. For photo enthusiasts who use either or both types of bodies, this lens is a must-have! It’s compact and lightweight, and is a versatile, convenient choice for use either as a main or second lens.
