Super wide angle single focus lens for full size with focal length of 20mm. The lens configuration consists of 14 elements in 12 groups.

With high point-image reproducibility, it is effective in shooting starry nights and night scenes. Nano AR coating suppresses flares and ghosts, resulting in clear, clear images.
The lens focus drive unit is equipped with two XD [eXtreme Dynamic] linear motors.
