I am a still photographer that has been photographing more video lately with the help of my son. I've been using a Nikon 750 and D4s DSLR for the video but last week I needed a running video which DSLRs won't do., I rented a Sony 30u which worked out fine. Now I'm thinking of purchasing a prosumer Video camera for future use. I've looked at the Sony CX900 and the Sony AX 100, the 100 is a 4k camera which I don't need now but should I be thinking about a few years from now? I would appreciate any advice.
Thanks,
Dave
