In early spring when I was first able to get out and play with my new A7 IV, things were fairly limited to backyard and around the neighborhood. I played some with the programmable button on the 200-600 and changed it to APS-C, and since I never use the button for focus hold (or anything else for that matter) promptly forgot about it. Of course this programming happens in-camera, so the same selection applies to any lens with a button, including the Sigma 100-400 and even my old Minolta A-Mounts. This bit me in the butt on Sunday. Without realizing it I evidently pushed the button several times, resulting in some full frame shots and some APS-C shots, which are around 13-14 MP. Fortunately the vast majority of these are going be viewed on a cellphone, so no big deal. I just hope none of the car owners or drivers want the full resolution version so they can print it large.
I need to change the button back to Focus Hold or something innocuous, or at least momentary. When APS-C is programmed it's a latched switch, that is to say it stays there until pushed again. The FH is momentary, so reverts as soon as the button is released.
Jeez.
