The NEX-5 actually records at 1080p 30fps, but, because of the AVHCD codec, it puts it in a 60i wrapper. Once inside your NLE, it is treated as 30p.
A900 with a few lenses, flashes etc.
Thanks Douglas, you're right. I didn't say what I meant to say, which is I'd like the NEX-5 to be hacked to record 1920x1080p in MP4 format (instead of 1440) at around 20 or 30Mbps.
roweraay- I think the reason for the fondness of 60i wrappers is that they can use this mode for recording and use the same hardware/software for outputting to TVs. Maybe older tvs can handle 60i but not 30p? (considering most people buying the camera are likely consumers...)
