The photography crowd might laugh at Arri’s use of the term “large format” when we’re talking about a sensor only a hair larger than a “full frame” DSLR or mirrorless camera. When it comes to video, though, that is rather large. At 36.7 x 25.54mm, the sensor offers 4.5K (4448 x 3096) resolution and is the same one found in the much larger Alexa LF released last year.
The newly announced Alexa Mini LF cuts the size down dramatically over the full sized Alexa LF and is compatible with LPL and PL mount lenses, supports full frame and Super 35mm recording as well as all anamorphic de-squeeze ratios. It has three built-in 0.6, 1.2 and 1.8 ND filters, and records to both Apple ProRes and Arri RAW.
