(1) Lens Mount
Positive locking (PL) 54 mm stainless steel lens mount with Lens Data System (LDS) contacts.
(2) Close Focus
Close focus is measured from the film/sensor plane.
(3) Magnification ratio
Magnification Ratio is the relationship of the size of an object on the film/sensor plane (first number) to the size of that object in real life (second number) at the close focus setting; horizontal (H) and vertical (V).
(4) Length
Length is measured from the lens mount to the front of the lens housing.
(5) Length including flange focal distance
Length is measured from the image to the front of the lens housing.
(6) Front Diameter
Diameter of the lens/matte box interface.
(7) Entrance Pupil
The distance from the entrance pupil to the film/sensor plane at focus = infinity. Positive numbers indicated an entrance pupil in front, negative numbers indicated an entrance pupil behind the film/sensor plane. The entrance pupil (often mistakenly called "nodal point") is the center of perspective; moving the camera/lens system around the center of the entrance pupil prevents parallax errors. While largerly irrelevant for live action, this measurement is important for special effects work.
