The camera I own is the Black Magic Pocket Cinema Camera 4K. It is adaptable to both micro four thirds lenses. I have a Metabones Speed Booster to adapt EF lenses.
The low light performance of the camera is improved when paired with fast lenses and can perform slow motion footage with 60 FPS at 4K and 120 FPS at 2.6K.
This makes it perfect for scenarios that include sports and nature.
The three main high quality lenses I work with are the Sigma 10-20mm f3.5, Sigma Art series 35mm f1.4 and the Canon 70-200mm f4.
These lenses will cover the range of needs in any job. They are incredibly sharp and crisp and when paired with the Speed Booster they let in almost a full stop of light. For example the 70-200mm f4 lowers down to f2.6 making the low light performance even better.
