It just occurred to me how good the new Panasonic LX100 could be on a drone. It's smaller and lighter than the GH4 and has a great little lens on it.

Anyone else thought about this?

I'm ahead of you on that one Dave - see here ;-)

I guess the 15-minute time limit in 4K mode won't be too bad as most drones don't fly for very long anyway.
