Having sold my F3 recently, I then turned around and invested half the sale price in a new (to me) Black Magic Pocket Cinema Camera. Best part about the camera is the size and raw recording. I got a little too excited and had to film with it the same day, so I charged some batteries while editing, then ran out to Fort Langley to film around 10pm.
This exercise really taught me that this camera is not a low-light camera at all! It still handled decently, but I hope to never have to push it this far in the future for personal projects, and will flat out refuse to for any professional projects!
