This enables a sharp resolution with a minimum of colour blurring. Various types of protective coatings, prevention of reflections on the inner side of lens, and a large hood are used for rendering results with a transparency and reduced ghosting and flare.

Quick AF/MF switching is also possible, and an inner focus system enables easy MF operation. The lens includes a rotating tripod seat with clip to enable speedy switching between vertical and horizontal orientations.
