The D-20 is ARRI's concept of a practical digital movie camera. Like the Panavision Genesis, it uses a single image sensor the same width as a standard 35mm film frame, but unlike the Genesis, this also has the same height as a 35mm frame.
The D-20 uses a custom-designed CMOS sensor rather than the older CCD technology of the Genesis. Instead of the Genesis's RGB stripe filter, the D-20 uses a Bayer Array, similar to that used on digital still cameras. The CMOS sensor's "native resolution" (before the color mask is applied) is 3018 x 2200 pixels, which allows a 1920 x 1080 standard HD output with a resolution similar to the Genesis. Recording can be either on HD Beta tape or a hard disk array.
The D-20 is actually based on a modified ARRIFLEX 435 film camera chassis. It can use any "PL-Mount" cinematography lens, and was specifically designed to be as familiar in operation to a film camera operator as possible. In particular, it retains the rotating mirror shutter/reflex viewfinder that is standard on all ARRI film cameras, which allows the incorporation of a standard optical viewfinder.
This has the advantages that:
- The optical viewfinder image can safely be used for critical focussing, whereas current model electronic viewfinders tend to have insufficent resolution for this.
- No power is needed while setting up a shot, nor is there any particular need for a "video village" of monitoring equipment.
- The camera operator can see outside the frame that is actually being recorded, so (s)he (and/or the focus puller)"can see what's coming". (A major shortcoming of all-electronic viewfinder systems is the camera operator can only see what is actually being sent out to the recording system).
At present (Oct 2005) the D-20 is still undergoing refinement and to date no commercial projects have been shot with it. It has been observed that ARRI seem far less serious about the D-20 than Panavision do about the Genesis, since the CMOS sensor it is based on was principally designed for use in ARRI's anvanced film scanner, the Arriscan.
History of the D-20Edit
Currently, as of during the Sundance Film Festival for 2006, there is only one ArriFlex D-20 located in the United States of America. In about a month from the festival, Arri Rental facilities should have the D-20 available for rent. However, rental prices are still unknown.
