PRODUCT INFORMATION 
ZEISS DISTAGON T* f/2.8 15mm ZM
A fast aperture lens, excellent for hand-held photography.
 |
|
| This ultra wide-angle lens
is the pinnacle of modern rangefinder lens design. The Distagon T* 2.8/15
ZM is a rectilinear lens with very dynamic perspective effects for
critical architecture and interior photography. It is a fast lens for the
focal length, allowing for hand-held photography under difficult lighting
conditions. The lens is made in Germany and incorporates a very complex
optical design using exotic optical materials such as barium dense flint
with a high refractive index and fluor crown with anomalous partial
dispersion. It uses aspheric lens elements and an internal focus mechanism
for distortion-free images and consistent performance over the whole frame
and across the entire focusing range. The
standard centre filter compensates for the natural vignetting effect and
provides even tonal reproduction across the image field. When used with
the 15 mm viewfinder, the Distagon T* 2.8/15 ZM is an ideal match to the
Zeiss Ikon SW camera. Combined with a digital
rangefinder camera with a 1.3 crop factor, the lens has an effective super
wide-angle focal length of 20mm and also delivers impressive perspective
effects.
