Where can I buy the PANAVISION PRIMO STANDARD -SL- series

Panavision’s Academy Award winning series of Primo Prime lenses combine high contrast and resolution, even field illumination, and negligible veiling glare, ghosting, and distortion. Primo lenses intercut seamlessly with other lenses in the Primo line, and are designed for use with film and digital cameras. The standard (SL) series of Primo Prime lenses include focal lengths ranging from 10mm to 150mm with widest apertures of T1.9. Close focusing distances range from 2 feet to 5 feet 9 inches. All Primo Primes are compatible with the 1.4x Primo Extender which reduces your exposure by a full stop.
