Custom button map
Which functions belong on the a7C II's custom buttons?
Two maps: stills and movie
Sony gives stills and movies separate assignment sets in the same menu. Build both — a key set for stills does nothing for you the day you switch to video. Button 1: Focus Area. Button 2: Recognition Target. Movie map: Auto Framing. Note the absence: this body has no joystick to assign.
Button 1 — Focus Area
The area change is the most common mid-shoot move there is: portrait to action, Spot to Tracking. Buried in the Focus menu it costs you the moment; on a button it costs one press.
Button 2 — Recognition Target
The AI unit is only aimed when the target is named. One press switches Human to Bird to Animal as the subject changes — no menu dive while the moment leaves.
Movie map — Auto Framing
For solo video, Auto Framing crops and follows you in frame. It is a movie and streaming tool only — which is why it belongs on the movie map, not crowding the stills one.
The map lives in Memory 1
Button assignments are part of a registered setup. Save the finished map to slot 1, and the mode dial restores your settings and your keys together.
Assign Custom Button 1 → Focus Area, then shoot for a day before adding the rest. Muscle memory is built one key at a time.
