Hi Kyle - thanks a lot for your help!
I am normally filming landscapes and people interacting with them (kayaking / paragliding / surfing / walking / climbing etc) - I think a good quality 60p would be good enough but any more than this would be awesome - as for battery life I am quite happy using lots of spare batteries & yes I have quite a few Canon L lenses...
Thanks again,
Ed

what is this doing on a filmmaking blog?

I use the Manfrotto 190 Light - it goes down to really low (if inverted) and pretty high! I would definitely recommend. But if you want one that goes really tall try the Manfrotto 290 Light...

Thanks Walter, £1.5k is quite a lot for a stabiliser! It is meant to be amazing though...

In my view the ability to get the Atomos Ninja Inferno - Prores + 4K from the A7S would be awesome. Sony RX100 V is also meant to be amazing (check out Tim Kelner's work - a lot of amazing films shot on RX100)

Thanks for that - I was looking at the Moza Air which looked quite good (anyone used one of them?)
