Hi I was testing the 70d any many other models in detail.
Thanks so much for your help!
It is clearly visible, 70d is the winner in terms of autofocus. Not only the speed, but also it is not pumping and hunting at all.
I saw on the a7s, most lenses are hunting very slightly before lock focus. Same for other cameras.
In terms of touch screen focus selection I think the camera needs to be on a tri or monopod as touching the screen will certainly shake.
For manual focus I tried the Olympus again and I found out some settings, which are really cool.
So as BC said my list of required features is a little bit high
go to strip down on that.
