What Does "Full Frame" Mean?
This comes from the Phase One website: Notice that Phase One refer to a digital 645 format equivalent sensor as "full frame". That is probably correct given that the largest format used in standard civilian photography is a 645 format sensor. In addition to the 645 (53.7 × 40.2mm; similar to the 56 × 42mm imaging frame size of 645 format film) and 4433 (43.8 × 32.9mm) format medium format sensor, some video cameras use sensors larger than 35mm (36 × 24mm) format e.g. 54.12 × 25.59mm Arri sensor. There is also the Leica S system with its 45 × 30mm format sensor. That means there are several sensor size formats larger than 35mm format making it increasingly difficult to hail something running in fifth place the leader in the size stakes. Newer video camera sensor formats are now growing larger than 35mm format It is probably only a matter of time before even larger digital photography 670 format sensors go into production though that may not happen for another 6-12...
