The short, high-power telephoto lens
The Sonnar® T* 4/180 CFE lens is often compared with the Sonnar T* 4/150 CFi lens. It offers 30 mm more focal length, which doesn't seem to be much of a difference at first glance. Who ever experienced both lenses knows, there really is a clear difference in angle of view. There is another significant difference: The optics of the Sonnar T* 4/180 CFE lens, although optimized for infinity, were designed with special attention to close-up performance. This results in a lens that gained high popularity with demanding fashion- and beauty photographers worldwide.
With this lens the optic designers managed to achieve a correction so high, that it can be used for
demanding product shots that need a focal length clearly longer than the Carl Zeiss Makro-Planar T* 4/120 CFE lens offers. The optical materials chosen make this lens very unsusceptible to thermal fluctuations, so it can safely be used in radiant heat from direct summer sunshine, heavy industry furnaces, jet propulsion test beds, rocket launch sites and the like. In fact, the Sonnar T* 4/180 CFE lens is a proven general purpose telephoto lens with stunning performance.
