CamerasArri Alexa Mini LF

Large format, small camera.

Arri's answer to their competition's ability to shoot native 4K resulted in them stitching two of the superb Alexa Mini sensors together and producing the large format sensor in the MiniLF. This started a roller coaster of lens manufacturers producing Full Frame options and a rush to rehouse vintage stills glass into useable, reliable options for cinematic shooting - all great news for Cinematographers with endless stylistic choice available at all manner of price points.
