The ultimate large diameter wide angle zoom lens optimised for full frame mirrorless cameras and perfect for astrophotography with astonishing resolution. One FLD glass and five SLD glass elements are appropriately arranged to suppress chromatic aberration to the edge of the frame. Three aspherical lenses including a large-diameter aspherical lens at the foremost surface are used to effectively minimize coma flare etc. thereby achieving mind-blowing resolution. The super multi-layer coating is combined with a newly developed NPC Nano Porous Coating. The lens has been designed to be less susceptible to strong incident light such as backlight. Incorporating a stepping motor enables the high speed quiet AF drive. Shooting is comfortable even in target AF such as Face/Eye Detection AF and during video shooting. The AFL button which can be assigned with various functions widens the range of operations available on the lens. Furthermore the lens features a dust- and splash-proof structure along with a water- and oil-repellent coating on the front most surface of the lens which further supports shooting in various environments. The lens comes with a rear filter holder equipped with a fall prevention lock for attaching sheet type rear filters for shooting starry skies.
