Positive locking (PL) 54 mm stainless steel lens mount with Lens Data
System (LDS) contacts
(2)
Close focus is measured from the film/sensor plane
(3)
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
(4)
Lens length is measured from the lens mount to the front of the lens housing
(5) Diameter of the lens/matte box interface
(6) The distance from the entrance pupil to the film/sensor plane. Positive
numbers indicated an entrance pupil in front, negative numbers indicated
an ent rance 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.
(7)
The image diameter (ID) is the diameter of the image circle needed for the
respective format. These lenses are designed for the largest ID given here.
