Camera: Sony EX-1
Adapter: Redrock Micro M3 Adapter w/PL Mount
Lens: Cooke Panchro 50mm/75mm
Format: 720 24p @ 24-60fps
Notes: This test was done in bright/harsh daylight to test how far we could stop down before seeing grain (the plague of many adapters - where you often can't go past a 5.6 without seeing the ground glass).
We were able to achieve a 16 stop without any grain - we would have stopped down further but then we wouldn't have exposure.
