Carl Zeiss 21mm F/2.8 Distagon T* Nikon

**The new horizon** This legendary super wide angle lens will set new standards in its focal length class. Exceptional color control allows for extraordinary high contrast pictures without any color fringes. Thanks to the Carl Zeiss T * anti-reflection coating and its outstanding attenuation of stray light, the Distagon T * 2,8 / 21 provides brilliant results under all lighting conditions. With a close focusing of only 0.22 m (0.72 ft) it is as attractive for landscape photography as for subjects with dramatic perspectives. The large front filter diameter allows for the use of standard screw-in filters and effective lens shades.**Tekniske specifikationer:**- Focal length 21 mm- Aperture range f / 2.8 -- f/22 (1/ 2 stop intervals)- Number of elements / groups 16/13- Focusing range 0.22 m (0.72 ft) -- 8- Angular field* (diag. / horiz. / vert.) 90 / 81 / 59°- Coverage at close range 18 x 12 cm (7.1 x 4.7")- Image ratio at close range 1: 5- Filter-thread M 82 x 0.75- Length (with caps)** 109 - 112 mm (4.3 - 4.4")- Diameter** 87 mm (3.4")- Weight** 600 - 720 g (21 - 25 oz.)- Camera mounts ZE (EF bayonet) ZF.2 (F bayonet with CPU)- Scope of delivery Lens Shade included *referring to 35 mm format\**dimensions and weight may vary according to the camera mount
