I was trying to keep clear of the brand wars ;-) A7
A worthy goal, and for all I know, all ILC systems have such an AF+MF mode these days --- though it might be easier to implement in lenses that use focus-by-wire, to avoiding the clash of manually turning a mechanically coupled focus ring one way while the AF motor is trying to move in the opposite direction.
Instead of AF or MF, how about a more dynamic focus control system that took MF actions as a directive to identify what AF should bring into focus: MF to AF to MF to AF…
I look forward to camera makers experimenting with ideas like that. At risk of heresy, I can see enhanced touch-screen controls being useful even when using the eye-level VF so that the touch-screen cannot be seen.
For example, one current camera [brand name suppressed to keep the peace] offers some ingredients that have potential for "manual selection of AF point", but they could work together far better than they currently do:
1. Select focus region (by touch on the rear screen, which only works when looking at that screen rather than using the eye-level VF)
2. zoom the preview to the selected focus region (by a preselected magnification factor; done with a press on one of the programmable buttons)
3. AF on the zoomed region (done with a half-press and hold of the shutter release). This can gives precise selection of a very small AF target if the maximum preview magnification is selected, generally making MF unnecessary if just slight camera movement is allowed to get the focus target right in the bull's-eye.
4. unzoom the preview, to check and fine-tune framing (done with another press on that programmable button)
But I struggle to use the current implementation of this, so I would like:
a. to be able to do step 1 with my eye to the VF, by "tracking" my finger over the rear touch-screen or with a touch pad in place of the four-way arrows
b. to adjust the degree of magnification at step 2 quickly on the fly, maybe with a touch-screen gesture or a slider
c. to avoid step 4, by the option of a "window-in-window" preview.
