LDS 100mm T1.9

ARRI 100mm LDS Ultra Prime Lens retain its excellent image quality even at close focus across the whole Super 35 frame.

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 thanks to integrated encoders and electronic contacts, easing tasks on set and providing valuable metadata for postproduction.

All lenses in this set have a rigid, very robust housing. The overall length is constant over the entire focusing range. The completely new focus drive mechanics are particularly sensitive and free of backlash.

Features of 100mm LDS Ultra Prime Lens

  • Super colour matched with Ultra Prime, Master Prime, and Alura Zooms and constant position of scales
  • Floating elements for outstanding close-up performance
  • 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 (PL-LDS) for lens metadata

Ultra Primes would be a perfect companion to ARRI ALEXA or AMIRA cameras.

ARRI Ultra Primes LDS Series include:

(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″)
