Carl Zeiss Otus 1.4/85 SLR Lens (SLR, 11/9, Macro Lenses, 0.8 m, M86, 1.4-16)

Portrait length lens for Nikon F Mount FX DSLR and 35mm film cameras. It is also compatible with DSLR in DX format where it offers a focal length equivalent to 35mm focal length equivalent to 127mm. The f/1.4 fast diaphragm benefits in difficult lighting conditions and also allows ample control over focus placement for flat focus depth and selective focus applications. An aspherical element and six anomal dispersion glass elements help eliminate chromatic aberrations to ensure better clarity and color accuracy at the thematic edges, regardless of the aperture setting used. Based on the optical concept of planar, this apochromatic lens virtually eliminates both chromatic and spherical aberrations to reduce color fraying and color type before and behind the focus level. A floating element places variable air columns between selected target groups for consistent performance across the entire focus range, from 2.6 inches to infinity.
