The Zeiss Planar T* 1,4/85 ZE 85mm f/1.4 Lens For Canon  is a short, high speed telephoto lens built for the exacting SLR photographer. It provides an unusually bright and clear image in the finder. Even at full aperture, it delivers top image quality.
Its angle of view and exceptional performance make the Planar T* 1.4/85 ZF the lens of choice for portraiture on location or in the studio.
Now offered as a "ZE" type lens, which makes it compatible with any camera that uses the Canon EF bayonet lens mount. All existing exposure programs (P, AV, TV, M) and the AF verification function of the camera are supported, and lens information (focal length and speed) is passed on to the camera. Certain functions that require the use of AF lenses (various subject programs, A-DEP) are partially unavailable.
The lens' shallow depth of field at wide apertures allows the use of selective focus. This helps to emphasize the primary subject by defocusing the background.
The 9-blade, circular aperture produces a smooth and natural rendition of defocused images, as well as nearly circular shapes of point sources of light.
Geometrical distortion is imperceptibly low, allowing high quality documentation photographs, both analog and digital.
Revel in the moment
Pinpoints of light in the background envelop the individual and conceal a mysterious message. The Planar T* 1,4/85 lens brings out the best in its subject, while masterfully manipulating both sharpness and soft focus.
This classic portrait lens captures people in their surroundings, playing with a range of sharpness, soft focus and contrast effects. Its distinctive circular bokeh is a crucial creative element. The Planar T* 1,4/85 produces very high quality and shallow depth-of-field when wide open. This is especially suitable for isolating the main subject from the foreground and background. This lens is also suitable as a general-purpose lens.
The famous symmetric lens design invented by Dr. Paul Rudolph at Zeiss in 1896. The Planar lens is the most successful camera lens design – and, by the way, the most plagiarized - ever created. It provides the lens designer with numerous means to correct aberrations extraordinarily well. And its performance is very constant over a wide range of imaging ratios, enabling such a versatile lens variety as the Makro-Planar lens.
Floating Elements Design
State-of-the-art camera techniques and high-resolution digital image sensors increasingly demand more from the lenses. The modern floating element design compensates aberrations of the Zeiss SLR lenses at different distance settings. This is accomplished by changing the axial distance of single lens elements or element groups to each other. The adjustment of the element distance is coupled to the distance setting so that it always results in the right correction. The mechanical design of these lens elements is very complex and the workmanship must be particularly exact - both specialties of Zeiss.
Excellent image quality
The Zeiss range of T* lenses offers the highest possible standards in terms of performance, reliability and, of course, image quality. Quite simply, they are superior in every way. You can count on highly advanced flare control for crisp and brilliant images, for example. And virtually zero geometric distortion, ensuring precise accuracy when reproducing shapes – especially useful when photographing products and architecture.
Elaborate stray light reduction
Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light. For example, all lens elements are coated with the famous Zeiss T* anti-reflective coating. Additionally, a jet black special paint is applied by hand to all lens element edges to ensure that reflections are prevented from the start.
Precise manual focus
Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. Zeiss SLR lenses stand out with their large rotation angle which enables 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. The precise engraving in meter and feet, and the depth of focus scale provide additional support for manually focusing.
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.
