THE ULTIMATE ULTRA-FAST WIDE-ANGLE PRIME LENS FOR DSLRS This full-frame optic was the first full-frame 20mm prime ever built with an F1.4 aperture, making it one of the most desirable lenses on the market for astrophotography, weddings and interiors. Not only does the lens allow four times the amount of light on the sensor than an F2.8 lens with the same ISO and shutter speed, but the wide-aperture also creates a very shallow depth-of-field for pronounced subject separation when shooting portraits or closer-up objects. Thanks to its advanced optical, which includes 5 SLD, 2 FLD and 2 aspherical elements, the lens has exceptional resolving power, delivering highly-detailed images with excellent sharpness and accuracy from the centre to the periphery of the frame. There is also very well-controlled coma flare, vignetting, distortion and chromatic aberration, ensuring a near-perfect image straight out of camera.
