While most extenders can only physically fit on a limited range of lenses, the design of the PLx2 accommodates more spherical and anamorphic PL mount lenses than any other doubler on the market. This is achieved by designing the extender with a deep-set optical assembly, thus, making it possible to use lenses with long protruding rear elements

Optically, the PLx2 projects an image circle large enough to cover all commonly used 35 mm formats including 5K on RED Epic and 4:3 full frame on ARRI Alexa
