The latest addition to the Zeiss Otus lens family is the Otus 1.4/100, which adds a new telephoto focal length.

Offering the same levels of performance as other lenses in the family, the new 100mm lens claims to deliver ‘the quality and look of a medium-format system’. This manual focus lens has been designed with relatively few glass-air surfaces, following a Sonnar design developed by Dr. Ludwig Bertele at Zeiss in 1930. Comprising 14 elements in 11 groups, including an unspecified number of aspherical elements, it boasts an aperture range of f/1.4 to f/16, a focusing range from one metre, where the reproduction ratio is  1:8.6, to infinity. No stabilisation is provided.

The lens is not yet available in retail outlets and no pricing is available, although a figure of US$4500 has been suggested. Click here for more information.
