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 Distagon T * 2,8 / 21 with F bayonet (ZF), EF bayonet (ZE)
and K bayonet (ZK) is suitable for analog or digital full-frame SLR cameras. The large front fi
lter diameter even allows for the use of standard screw-in fi lters when combined with the
standard lens shade.
