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.
