D500 wildlife filmmaking - focussing?
Hi after buying a drone and shooting a bit of video with it I'm getting more into video again. When i was at my favourite waterbird spot yesterday to shoot stills I took a bit of video and enjoyed it and was quite happy with some of the results (https://www.youtube.com/watch?v=53hxYNZ3w6g)
I do need a bit of practice though - some clips were overexposed and i relied on autofocus that didn't work that well in video it seems. The VR worked well - it was all hand held but resting on the window sill of my car shooting out the window.
So yeah my question is about focussing... i was pretty good with manual focus back in the day with a Hi8 video camera filming motorcross etc.. but I was a bit younger then with better eyesight etc
I'm thinking perhaps I need an external monitor on the D500 to assist with manual focus? If this is a good idea I do have an ipad mini 4 that i'm wondering would be good to use with a hotshoe mount.. would this and snapbridge be a solution? Or a HDMI adaptor for the ipad mini somehow?
I would love to be able to use the viewfinder to focus but as I understand the mirror has to be up for videoing.
Any advice much appreciated.
