Full Details

Dynamic wide angle design
By offering a field of view of 94Ëš, the EF 20mm f/2.8 USM is able to take in the complete field of human vision, and much more. A great lens for the landscape or documentary photographer. Distortion is highly corrected, for a natural perspective when shooting architecture and interiors.

Fast maximum aperture
A maximum aperture of f/2.8 allows flash-free, hand-held shooting in low-light conditions when using a tripod is impractical.

Aspherical and UD elements
For optimum visual performance, the lens incorporates aspherical elements, to correct spherical aberrations, and Super UD (ultra-low dispersion) elements to eliminate chromatic aberrations. The result is crisp, high-contrast undistorted image quality all the way across the frame.

Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Super Spectra coating
Super Spectra coatings help ensure accurate colour balance and high contrast. They also suppress flare and ghosting by absorbing light that would otherwise be reflected off internal lens elements and the camera's digital sensor.
