The Hasselblad 30mm f/3.5 Distagon "fisheye" lens is for creative photography. Fisheye lenses are like ultra wide angle lenses with an interesting difference: straight lines only remain straight when they pass through the center of the picture. The closer they are to the edge, the more curved they will appear. The 180 degree diagonal angle of view and extreme depth of field of this design opens up new possibilities not possible with other lenses.
CF lenses constitute Hasselblad's main lens series with focal lengths from 30mm to 500mm and are intended primarily for the 500 series cameras. They have built-in leaf shutters with speeds up to 1/500th second and flash sync on all speeds.
