I've just completed a shoot using the Sony PMW 200. A really good camera. I am considering purchasing the PMW 300 which understand will be available in Oct/ Nov 2013.
I have a question. Will this camera be able to record in 4.2.2 @ 50mbps using SD cards - either in the SD port or using SxS card adaptors in the SxS port? I've looked at several sources online and the impression I get - its not entirely clear - that SD cards in the PMW 300 will only give you a maximum of 35mbps. If anyone can clarify this for me I would much appreciate it.
The MS and SD media supports UDF and 50Mbps, HD422 recording is not possible. However, XQD cards support both UDF and FAT formats and can be used with the PMW300K1 with an appropriate adapter. I hope this helps!
