While the Signature Primes exemplify state-of-the-art optical precision, they have been designed to render organic images with natural skin tones and creamy bokeh.

  • Front Diameter 114mm  //  LPL Mount
  • -18mm T1.8
  • -25mm T1.8
  • -35mm T1.8
  • -47mm T1.8
  • -75mm T1.8
  • -125mm T1.8


When using the Signature Primes on an Alexa Mini (S35 sensor) the focal lengths are the same equivalent lengths you’re accustomed to.  When shooting on large format sensors (Alexa LF, Sony Venice, RED Monstro) the equivalents are approximately 1.5X wider.  From a 24mm wide sensor (Alexa 2K) to 36.7mm sensor (Alexa LF-opengate), the multiplication = 1.529.  The exact number depends on which sensor and the area of the sensor you are using.  To calculate equivalent focal lengths use the following formula:

a = 2 * arctan(.5 * F / f)

Where a is the Angle Of View, F is the film-back size and f is the focal length (with F and f in the same units).  Here’s 1.5X with some rounded numbers below for quick reference.

  • 18mm= 12mm
  • 25mm= 17mm
  • 35mm= 23mm
  • 47mm= 31mm
  • 75mm= 50mm
  • 125mm= 83mm
