Edwin Rose-Cinematographer

The benefit of the MBP would be the portability . The new imacs are more powerful for the most part. I would personally prefer a MBP but they have not released the one with the right specs compared to the High End imacs. I would go with the imac or wait a little longer to see if another MBC will come out.

The BMCC is a cinema camera so there will be extra things you may need. THe same thing can be said with any other cinema camera. Once you have those things yes it could be used for a Wedding. I personally would use it for creative shots. Also recording in Prores will not take up nearly as much space on the SSDs as the RAW workflow. You could get away with using maybe 512gigs and be able to cover over 5 hours of a wedding in Prores. Most ceremonies last an hour which leaves 4 hours for pre and post. I typically would be very meticulous on my shots for a wedding reception, mainly getting highlights of the key moments etc. so in my case 512 would work just fine.
