Coming from another professional who has used, Dedicated cams, Canon, Sony, Mini Lf, and BM cam systems. I’ll tell you the FP was definitely aimed at the BMPCC market.
Very similar in features and I will agree the auto focus is better. That said, not sure anyone in the cinema field is gonna be using auto focus much anyway. I pull focus for just about everything I use.
The fact that the production team of the Halo series ditched the BMPCC for the FP shows what cinematographers are looking for in an on-set POV Cam. It was throwin punches with Arri cams. That is serious. The reason is because it is the only pocket cam that shoots true RAW Cine DNG. I have the FP-L and can attest to the quality. I will say though the RS is there. Not much worse though than other cams out there with no Mech. shutter. It’s expected. One word Gimbal… hehe. I’m happy with my buy. I don’t use it for extreme action though, and don’t get me wrong I love Black Magic, but a camera that can give me CINE DNG, small form factor that you can rig minimalistic for travel and is Full frame… it’s a win for me.
