Dedication to all saying BMPCC (Blackmagic Design Pocket Cinema Camera) is not ISO king. It does not have to be. It’s just proper at what it does.
Three simple and fast stills from homemade footage. Winter afternoon, 40W bulb in the room.
Pocket: KOWA 12,5mm lens at f1.4, ISO1600, 180 shutter angle (1/48) vs Canon 6d, Tamron 24-70VC at f2,8 ISO6400, 1/50
Just as pointed: BMPCC does not have to be ISO king. It just works properly.
