Design and Features
The Vario-Sonnar T* 4.0-5.6/70-300 lens is a compact tele-zoom lens with autofocus and high image quality for the Contax N1 SLR system. The zoom range of the Vario-Sonnar T* 4.0-5.6/70-300 lens covers all focal lengths of 35 mm photography which normally allow good results to be obtained without the use of a tripod. The smallest object size covered corresponds to the size of a postcard, the minimum object distance in front of the lens is 73 cm. The image quality obtained at this setting is remarkably good.
To achieve this high image quality, the Vario-Sonnar T* 4.0-5.6/70-300 lens also uses fluor-crown glass with anomalous partial dispersion. Distortion has also been very well corrected , allowing the Vario-Sonnar T* 4.0-5.6/70-300 lens to be used for product photographs, if necessary, if no macro lens is available or the longer focal lengths provided by the Vario-Sonnar T* 4.0-5.6/70-300 lens are particularly beneficial for picture composition.The optical and mechanical design is such that the lens requires relatively little space in its transport position. The Vario-Sonnar T* 4.0-5.6/70-300 lens is the ideal complement to the more wide-angle oriented Vario-Sonnar T* 3.5-4.5/24-85 lens and forms a lens pair with it, allowing the reliable performance of all tasks of 35 mm SLR photography – from landscape to small animals.
Preferred applications: All-purpose telephoto lens, traveling, landscape detail, snapshots, editorials, portraits, animals.
The type of autofocus motor is indicated according to Conurus. The lens can be converted to Canon EF mount with AF support by Conurus service.
