Product Information
Arri LDS Ultra Prime 20mm T1.9 Lens - Metre
Floating elements for outstanding close-up performance
Ultra Prime lenses were the first to be kitted out with ARRI’s revolutionary Lens Data System (LDS). The LDS Ultra Prime series consists of Ultra Prime optical elements transplanted into specially designed housings that allow each lens to communicate with the camera electronically, easing tasks on set and providing valuable metadata for postproduction.
Key Features:
- Covers Super 35
- Genuine internal focus for sensitive focusing
- Increased image contrast and resolution over the entire focal range
- Built-in encoders and electronic PL mount for lens metadata

- (1) 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.
- (8) Horizontal angles of view for a Normal 35 Academy camera aperture (aspect ratio 1.37:1, dimensions 22mm x 16mm / 0.8661" x 0.6299")
- (9) Horizontal angles of view for a DIN Super 35 Silent camera aperture (aspect ratio 1.33:1, dimensions 24mm x 18mm / 0.944" x 0.7087")
- (10) Horizontal angles of view for an ANSI Super 35 Silent camera aperture (aspect ratio 1.33:1, dimensions 24.9mm x 18.7mm / 0.980" x 0.7362")
