Extremely compact wide-angle lens without distortion The 14mm f/4 FF RL Zero-D is currently the smallest and lightest wide-angle lens with a 114° angle of view for mirrorless cameras with a full-frame sensor. It is only 5.9cm long and weighs just 228g. This makes it the ideal companion for the new compact full-frame cameras and perfect as an "always with you" lens for landscape, architecture and astrophotography. Although it is so small and light, no compromises have been made in terms of function, image quality and construction. In the solid metal housing, 13 lenses in 10 groups ensure maximum sharpness and minimal chromatic aberration and reduce distortion to an absolute minimum. The short focusing distance of 27cm allows creative wide-angle shots with sharpness right up to the close-up range. Thanks to the 5 aperture blades, a beautiful 10-beam reflex is produced when shooting against the sun or a point light source. In contrast to many other wide-angle lenses with large spherical front elements, this 14mm Lens only has a small front element and a 52mm filter thread. This means that 52mm screw-in filters and - with a holder available as an accessory - 100mm rectangular filters can be used. Focusing and aperture adjustment are manual.
