Vario-Sonnar T* 4-5,6/70-300
Tele-Zoom for the new Contax N1
This rather compact autofocus zoom lens has been designed to handle most of the day-to-day telephoto motifs Contax N1 users might face. It is the ideal telephoto complement for the more wide angle oriented Vario-Sonnar T* 3,5-4,5/24-85. The zoom range of the Vario-Sonnar T* 4-5,6/70-300 includes all focal lengths that can normally deliver good results without a tripod. The optical and mechanical design provides high performance with quite a small carrying/packing size of 88 mm diameter, 153 mm long, weighing 1.09 kg. The filter thread is 72 mm, non-rotating. A lens shade can be attached per bayonet mount.
Applied for macro photography the Vario-Sonnar T* 4-5,6/70-300 covers an object the size of a postcard (approximately 1:4). Even at this magnification the image quality is remarkably good. To achieve its high performance the optical formula includes 16 elements in 11 groups. Fluor-crown glass with anomalous partial dispersion is also used.
Special care has been taken to control stray light exceptionally well. Thus, the Vario-Sonnar T* 4-5,6/70-300 can even be used for product shots, if no Makro-Planar lens is available or if the longer focal length of the zoom lens is particuarly beneficial for creative reasons. | |
