ARRI chose the BSC Expo in London to unveil a complete 4K large-format system comprised of the new ALEXA LF camera, ARRI Signature Prime lenses, LPL lens mount, and PL-to-LPL adapter. True to ARRI’s practice of protecting their client’s previous investments, the new camera is compatible with existing lenses, accessories, and workflows.
Featuring a sensor slightly bigger than full frame, ALEXA LF records native 4K resulting in a 4448 x 3096 image in formats, including ProRes, uncompressed, and unencrypted ARRIRAW up to 150 fps. Accompanying the ALEXA LF camera are 16 large-format ARRI Signature Prime lenses, ranging from 12 mm to 280 mm and fitted with the ARRI LPL mount and share a T-Stop of T1.8.
Although the camera, lens mount, and lenses are new, full compatibility with existing PL mount lenses and ALEXA accessories is a cornerstone of the system’s design. A PL-to-LPL adapter offers backwards compatibility with all PL mount lenses, whether Super 35 or full frame. The adapter attaches securely to the LPL lens mount without tools, allowing crews to rapidly switch between PL and LPL lenses on set, and offering cinematographers a wide choice of lenses.
The first ALEXA LF cameras will be shipped at the end of March 2018. The initial set of four Signature Prime lenses (35 mm, 47 mm, 75 mm, and 125 mm) will be shipped in early June 2018. The remaining lenses will be available over the course of the year.
