This elegant Tele is the ideal travel companion for portrait and landscape photography and offers
stunning images at nearly any distance.
Tele-Tessar T* 4/85 ZM
Come a little closer.
Combined with a 35 mm Biogon wide-angle lens, the Tele-Tessar T* 4/85 ZM makes for a classic combination for countless fascinating subjects. The image quality of the Tele-Tessar T* 4/85 ZM is equal to the high aperture models in the lens program. It is almost distortion free and adjusted to the field of curvature as well as to all other defects in color. With the shortest camera-to-subject distance of only 0.9 meters it delivers brilliant pictures at any distance. The all-metal mount and the robust construction turn it into a universal tele lens, even under extremely rough
conditions.

Features
Robust design
The mount and control elements of all ZM lenses are made of metal and are designed for decades of intensive use. The high-quality craftsmanship of the all-metal mounts, the easy-to-grip metal focus and aperture ring and the robust front bayonet and filter threads ensure an amazing photographic experience.
Smooth, precise focusing
Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. The user-friendly focusing ring on ZEISS lenses with an ergonomic finger rest is perfect for fast, precise focusing. Changes are immediately visible in the viewfinder. The high-quality focusing mechanism moves smoothly without play, thus also supporting the intuitive interaction with the focal plane.
Minimized Focus Shift
ZEISS T*® ZM-mount lenses are specifically designed to minimize focus shift with aperture changes – an important innovation with big benefits for rangefinder photography. As a result, you can expect improved accuracy of the rangefinder-defined focus. While the precise 10-blade aperture with 1/3 stop interval click stops ensures exact exposure.
ZEISS T* anti-reflective coating
All lens elements in SLR lenses from ZEISS feature the T*® anti-reflective coating and an optical design that produces brilliant pictures even in unfavorable lighting conditions. We vacuum deposit very thin, transparent coats on the surfaces of the lens elements to make them anti-reflective. Special substances, one by one, are vaporized with very high energy in a high vacuum, which are then deposited on the glass surface as a coating with precisely controlled thicknesses to achieve the desired reduction of reflections. The first coatings were applied by ZEISS back in the 1930s.
Ideal aperture properties
Photographers want to guide the observer through the image. Minimal depth of focus is often used as a design element. This keeps the background intentionally blurred to keep the attention of the observer on the main subject. The ZM lenses feature ten aperture blades. The almost circular aperture helps to create a particularly harmonious effect in the out-of-focus areas of the picture (bokeh).
