The ALEXA Mini LF uses the same sensor as the ALEXA LF. This is the ALEV 3 A2X sensor, which has the same photosite size and type as ARRI Super 35 digital cameras. The ALEV 3 A2X has 4448 x 3096 photosites (yes, it is therefore a 4.5K sensor) and measures 36.70 x 25.54 mm / 1.444 x 1.005″ and requires a 44.71 mm / 1.760″ image circle.
The ALEXA Mini LF (left) has the same dimensions and the same mounting points as the ALEXA Mini (right), except for the media bay on the camera left side. The ALEXA Mini LF camera body with an LPL lens mount weighs 2.6 Kg/5.7 lbs. The ALEXA Mini LF MVF-2 viewfinder weighs 800 g/1.7 lbs.
The ALEXA Mini LF has an input voltage range from 11 V to 34 V. Therefore, it can be easily powered by any 12 V on-board battery as well as by a 24 V on-board battery. The ALEXA Mini LF has a power draw slightly higher than the ALEXA Mini, at around 65 W when recording ARRIRAW at 24 fps with the MVF-2 viewfinder connected. Electronic accessories will, of course, increase power draw.
