(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.
