With its wide angle of view and extended depth of field, the EF 20mm f/2.8 is a great choice for photographers shooting landscapes, architecture or reportage. A lens that can be used almost anywhere. By offering a field of view of 94˚, 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.
A maximum aperture of f/2.8 allows flash-free, hand-held shooting in low-light conditions when using a tripod is impractical. 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.
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 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.
