Arriflex D-21

The Arriflex D-21 is a film-style digital motion picture camera introduced by Arri in 2008 to replace their earlier generation Arriflex D-20.
Overview.
The D-21 uses a Super 35 (4:3 aspect ratio) sized single CMOS sensor and accepts 35 mm film camera lenses (54mm PL mount). It features an optical viewfinder and modular construction.
The D-21 captures images in three general modes: "HD" ('HD422 (16:9)' or 'HD444 (16:9)'), "Mscope", and "Data" ('ARRIRAW (16:9)' or 'ARRIRAW (4:3)'). Its sensor is a CMOS chip with a Bayer mask, with dimensions of 2880x2160 pixels.
