The 40mm Master Prime is one in a set of 16 from ARRI/Zeiss featuring excellent resolution, advanced contrast, almost no breathing, and a fast T1.3 aperture for achieving shallow depth of field. Ranging from 12mm to 150mm, the Master Primes offer the skin tones and color rendition for which Zeiss is noted, and are color-matched for consistency across the set. These lenses incorporate an iris with at least nine blades for cinematic-looking bokeh with distinct focus fall-off. Dual floating elements provide optimal close-focus performance while minimizing breathing when focusing. The advanced T*XP coating reduces reflections and glare while improving contrast.
Designed with aspherical elements for minimal chromatic aberration, the ARRI/Zeiss Master Primes provide optimal image quality and clean chroma-keying. High resolution is maintained in image corners even when the lens is used wide open and at close focus. Each lens features a PL mount and a built-in LDS system for transferring lens data to compatible cameras. The expanded focus scale has generous room for marks, and it sports fluorescent engravings for easier viewing in low-light settings. The focus ring has markings in both feet and metric; the ring may be reversed from one to the other by a qualified shop technician.
This 40mm Master Prime Lens features a 16" minimum focus distance, focus marks set in meters, a relatively light weight of 5.1 pounds, and a compact length of 8". This family of lenses feature consistent placement of focus, iris, and zoom rings for easier use with follow focus, zoom control, and F/I/Z wireless systems. Most of the lenses in the Master Prime family, including the 40mm, have a uniform 114mm front diameter, enabling the use of the same size matte box adapter, filter, etc.
