Carl Zeiss Touit 12 mm f/ 2.8 Lens 用户指南

Distagon

* f/2.8 - 35 mm

The high-performance Distagon

lens is a lens for

those who are interested in the medium wide-angle

range and who view high performance as
extremely high image quality and not as extremely
wide initial apertures. Together with a Sonnar

lens with a medium focal length and a Planar

lens

with a standard focal length, this Distagon

lens

should be part of the standard equipment of any
ambitious photographer.
In line with the above approach, i.e. dispensing
with the requirement for wider initial apertures

which would result in an excessive increase in the

front lens diameters - particularly with wide-angle
lenses -, Carl Zeiss now provides this 6-element
Distagon

lens. This 35 mm Distagon

* f/2.8

lens displays excellent image quality and very good
field illumination even at full aperture. At the same
time it features small dimensions and relatively low
weight. The applications of this Distagon

lens are

so varied that it can be described as a universal lens
for general photography.
