Zeiss Planar 2/110 mm HFT PQ
High-speed lens for portraiture and news photography.
Its wide aperture is particularly useful, for example, for
precise focusing in portraiture and fashion work. Mini-
mum distortion and high image quality even at maxi-
mum aperture and close up are the strong points of
this lens.
Cat. No. 711.81.052
Schneider Apo-Tele-Xenar 4/300 mm HFT PQ
Its high speed and apochromatic correction make this
an extraordinary lens that sets new standards in its
class. Used with a 1.4x Longar teleconverter, the lens
becomes a 40mm supertelephoto with a maximum
effective aperture of f/5.6.
Cat. No. 711.81.036
Schneider Variogon 5.6/140 – 280 mm HFT PQ
A zoom lens with macro setting, zooming without refo-
cusing and a minimum focusing distance of only .5 m.
In the macro setting, close-ups are possible down to
75 cm from the front lens. The lens takes the place of
several lenses of fixed focal length and is particularly
versatile due to its macro setting. Often enough it is the
only solution to filling the frame from a given camera
station. Its optical performance is equivalent to that of
fixed focal lengths.
Cat. No. 711.81.038
Ultra-fast PQ Lenses and Special-purpose Lenses
from Zeiss and Schneider
High lens speed is particularly valuable in reflex photog-
raphy. Apart from its optical benefits, there is higher
focusing accuracy due to a brighter viewfinder image
and shallower depth of field. The selective use of shal-
low depth of field and fast shutter speeds is particularly
attractive to the creative photographer. However, these
ultra-fast lenses are not only pioneering optical designs.
No less impressive is the fact that these wide apertures
have been combined with a between-the-lens shutter
with speeds of up to 1/500 second, in the case of the
Super-Angulon even to 1/1000 second. To solve this
problem, the shutter blades are not made of conven-
tional steel, but of a carbon-fiber laminate that reduces
their mass to 60 %. Another advantage of this super-
thin multilayer material is its excellent sliding character-
istics. One final factor is that the efficiency of the linear
motors used has been increased through the use of
neodymium magnets.
