Raw precapture is the single change I would like to see most in my Z9 and Z8s. (Of course there are many other improvements that would be nice.) I’d take HE* and something less than 30 fps if needed, if the change comes in new firmware. I can’t see buying a Z9II or Z8II as an upgrade without raw precapture. And if it comes in a new camera, rather than a firmware update, I think the performance bar would be higher. I think I’d want at least 30 fps with HE* in a new camera.
