Best dslr for focussing while shooting
I am looking at different cameras with focusing in mind (leaving aside all other considerations for the time being since I don’t need help weighing those).
I have shot 4 half hour documentaries with an EOS 550d and the slowness of the focusing proved very limiting and consigned me to static shots and made it very hard to capture fast moving developments. Remember that this is documentary so the movements of the subjects cannot be controlled as it would in a scripted shoot.
I like the idea of Canon’s touchscreen focusing with dual cmos that allows you to to shift focus while filming just by touching the screen where you want it to focus. I believe it is very fast.
The EOS 7d Mark II doesn’t have touch screen but can you move a cursor or box around on the screen to indicate where you want it to focus?
And what about the focusing on say the NX1 or GH4, do they allow you to “pull focus” by touching the screen at the appropriate place?
Or some other camera I haven’t mentioned?
Which of the DSLRs on the market then is the best for focusing with video?
I hear the GH4 praised for many reasons but there doesn’t seem to be any information on its focusing capability.
Which caera can track a moving subject and which allows you to refocus (or pull focus) quickest and cleanest while shooting (if the focus change is seamless then it can be included in the edit)
