A small-budget thriller called The Possession of Hannah Grace is the first Sony Pictures film to be shot on a full-frame mirrorless camera. Sony said that the film was primarily shot on its own A7S II, a consumer camera that costs a mere $2,000. "The smaller camera's ability to see beautiful under low light conditions, the LED lighting technology, and the [eco-friendly] methods we used in set construction made this whole production a case study in how to be efficient and still tell a great story with a fantastic look," said producer Glenn S. Gainor.
Attached to the body were Vantage's Hawk 65 anamorphic models, each of which likely cost multiple times the camera itself. Those squeeze the normal 16:9 4K image down by 1.3 times to a widescreen size (2.40:1), allowing for a more cinematic look while still using most of the sensor.
While the A7S II is extremely cheap by Hollywood standards, it can do things that much more expensive RED, Arri and Panavision models can't. The full-frame sensor has a very shallow depth of field, for one thing, and is famous for allowing shooting in very low light at very high ISO settings.
