Marty, no it would not be a simple change to increase still photo features on the Pocket Cameras, and this would take a new camera, with different hardware, and you might loose some of the excellent video magic, when you start making compromises required to add advanced still photography. With all the complaints on the current still button use issues, if BMD could do a quick fix, I am sure they would have done so. Perhaps they are working on this. We will not know until it gets released.
I understand your desire to keep your shooting simple and only hauling around one camera. I ended up getting a Nikon Z6 6K Camera for this very reason, before the Pocket 6K came out. When I am out in the field shooting stills with the occasional video shots, the Z6 works for me. When I want to shoot some serious video, with higher quality, I breakout my Pocket 4K camera. If I needed a higher resolution or was doing primarily full 4K shooting, than the Pocket 6K would fit the bill. When I am doing video work, I do not need any stills other than then occasional quick shot for a continuity check, and the current setup works for this. Yes, it is a pain not hearing the
click but I often turn this off on my Z6 too.
For background in mix camera use, Look at the GH5, great still camera IBIS stabilization, OK for video work, has compression limitations and no raw video recording, the came the GH5/S, improved video production, dual gain sensor, but no in camera stabilization, which had to go, to get the better video type sensor. Still, the GH5S takes still images, but limited to the sensor native 5-6K resolution, still no internal Raw or ProRes recording, due to limitations needed for the still photography requirements for the camera. Part of this is marketing the camera to avoid EU Pro Video production added taxes, and have one camera for world wide market.
BMD stripped the additional still photography functionality hardware requirements to get a pure Cinema quality video image, increasing the camera’s processor to concentrate on the camera IQ, and allow processing capability for higher end recording codecs and Raw Video recording in camera. So the compromise shifted more away from still photography use to Cinematic quality video shooting.
What you want is kind of like, trying to have your cake and eating it at the same time — hard to do.
