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.

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 420mm supertelephoto with a maximum effective aperture of f/5.6.

Cat. No. 711.81.036

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 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 2.5 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
