Wide-angle lens employs a Distagon optical concept to realize well-corrected imagery with virtually no distortion.
Fast f/1.4 maximum aperture benefits working in low-light conditions and also offers increased control over depth of field for selective focus shooting.
Two aspherical elements help to reduce spherical aberrations in order to realize a high degree of sharpness.
Three anomalous partial dispersion elements reduce chromatic aberrations and color fringing for improved color accuracy and clarity.
ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
Floating elements design helps to maintain consistent image quality throughout the focusing range.
Manual focus design enables a minimum focusing distance of 2.3'.
A 10-blade diaphragm contributes to a pleasing bokeh quality when working with selective focus techniques.
