VERY different cameras, but all can in fact create incredibly beautiful images. Speaking solely on imagery without other features, this is a briefing:
F55: 16-bit RAW at 4K/2K/1080 with 14 stops of DR.
BMCC: 12-bit RAW (from a 16-bit linear source) at 2.5K with 13 stops DR.
BMPC: 12-bit RAW (from a 16-bit linear source) at 4K with 12 stops DR.
F55: 1-60 FPS at 4K RAW, 1-240 FPS at 2K RAW.
BMCC: 23.98, 24, 25, 29.97, 30 FPS max at 2.5K RAW (and 1080 ProRes HQ).
BMPC: 23.98, 24, 25, 29.97, 30 FPS max at 4K RAW (and 4K/1080 ProRes HQ).
F55 has an S35 sized sensor with global shutter.
BMCC has a sensor that sits between S16 and M43 size with no global shutter.
BMPC has S35 sized sensor with global shutter (unheard of in this price range).
The F55 has an optional OLPF where the BMCC and BMPC only comes with no OLPF.
And imagery aside, the F55 does have a very nice feature-set when it comes to monitoring, audio IO, TC, etc., which all adds to its cost. I'd love to own an F55 myself and continually think about investing in one.
But speaking strictly image quality and not features, the BMCC/BMPC can stand on its own, it's that good. If you don't need all the features of an F55 or you know how to make due with out them, then the BMCC/BMPC can be a very powerful tool for shooting incredible images.
Wow! The best answer I've ever got on a forum, thanks man, do you think the pre-amp on the f55 is good for Microphones? and what microphones do you recommend if any and preferably wireless.. thanks again!
