20 mm F2.8

This rigrously 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 away from to cover with a "normal" lens. Meticulous attention has been paid to minimizing flare and internal reflection in this advanced design, with the result that excellent sharpness and contrast are maintained through the image.
