Zeiss Distagon T* 21mm F/2.8 ZF.2 Lens for Nikon F-Mount

The Zeiss Distagon T* 21mm f/2.8 ZF.2 Lens for Nikon F-Mount cameras is a manual focus professional lens with aperture of 2.8 and non-reflecting,  virtually distortion-free characteristics, Thanks to the legendary Carl Zeiss T * anti-reflection coating, the Distagon T* 21mm f/2.8 delivers outstanding results. Its wide aperture delivers fantastic performance for both daylight and in lowlight shooting. This lens is equipped with an F bayonet (Nikon) lens mount, and is ideal for landscape, architecture, portrait, group, and commercial photography.


DISTAGON DESIGN
Distagon is a retrofocus design that gives advanced control via an SLR viewfinder.  For extreme wide angles, the back focal distance has to be much greater than the focal length.  In such situations, Distagon is the ideal choice.

ZF.2 LENS
Zeiss ZF.2 are SLR lenses with F bayonet mount for Nikon cameras.   They support all key modes on all current Nikon DSLR cameras.  To do so, simply lock the aperture ring in the largest f-stop (e.g. 16) shown in orange. On camera models without an electronic interface, the aperture is manually set on the lens aperture ring. 

ASPHERICAL DESIGN
Zeiss' aspherical lens design creates a more complex surface profile.  This helps to greatly reduce spherical and other optical aberrations.  The design further ensures consistent imaging performance throughout the entire focal range, while delivering incredible sharpness up to the periphery of the image. 

MANUAL FOCUS
Manual focusing means you have all the control at the end of your fingers.  Zeiss lenses feature a specially designed ergonomic construction that is noticeable at first touch.  The large rotation angle of this lens guarantees precise focusing.  The mechanism moves super smoothly and without extra play, furthering the intuitive interaction along the focal plane. 

FLOATING ELEMENTS DESIGN
Optical aberrations are kept to a minimum, thanks to the use of the latest floating element design principles. This is achieved by variation of the axial distance between individual lens elements or groups. This adjustment of the lens-to-lens distance is coupled to the distance setting to ensure correct compensation at all times. The mechanical construction of these lenses is extremely complex and they must be assembled with utmost precision – both hallmarks of Zeiss.

ADVANCED APERTURE DESIGN
With Zeiss lenses you can create stunning Bokeh effects, thanks to the finely tuned features of Zeiss SLR lenses.  By keeping the background intentionally blurred, additional focus is created on the subject of an image.  The uniquely engineered diaphragm blades of this lens, along with the virtually circular aperture, deliver stunning renditions of highlights the back and foreground.
