The Vario-Sonnar T* 3.5-4.5/24-85 lens is a compact, all-purpose lens with autofocus and high image quality for the Contax N1 SLR system. The zoom range of the Vario-Sonnar T* 3.5-4.5/24-85 lens covers the most popular focal lengths in 35 mm photography, including extremely wide angles up to 84 degrees which are often necessary for the photography of interiors. The smallest object field which can be covered without accessories is 24 cm wide, with a minimum object distance of 35,3 cm. This makes the Vario-Sonnar T* 3.5-4.5/24-85 lens the ideal lens when you are out and about and especially when you want a versatile zoom lens as your standard optics, but expect it to deliver the same high image quality as fixed focal length lenses. To achieve this high image quality along with relative compactness, this lens uses elements made of special fluor-crown glass with anomalous partial dispersion, and additional aspheric surfaces. With M82, the filter thread has deliberately been given ample dimensions to allow the combination of high-quality filters with this lens without vignetting of the corners – even when wide-angle settings are used. In addition, a lens hood can be mounted using a quick-change bayonet.
