The 9 mm f/2.8 ZERO-D ultra-wide-angle lens is currently the most extreme wide-angle lens with a brightness of 2.8 for APS-C cameras. With a field of view of 113°, it offers photographers truly extraordinary perspectives.

With a length of 60 mm and a diameter of just 53 mm, it is ultra-compact and, at only 215 grams, extremely lightweight. This makes it the ideal companion for all mirrorless system cameras. It fits in any camera bag and even feels secure in a pocket.

Thanks to the small front lens, all standard screw-in filters with a diameter of just 49 mm can be used without vignetting. Two aspherical lenses and three lenses with extremely low dispersion minimize both chromatic aberration and optical distortions to an absolute minimum. Additionally, this design ensures excellent sharpness all the way to the corners of the image.
