My take has always been that Panasonic should have prioritized a smooth m43 to full frame transition for customers. Having a blended ecosystem would help both thrive. As it is now, customers have to choose FF or m43, often with FF perceived as having most of the benefits. I think the first round of FF cameras should have had a m43 crop mode with faster readouts and frame rates. And, the mount Panasonic developed should have somehow been compatible with m43 lenses via an adapter. This might have meant messing with the flange distance which maybe reduced compatibility with other lens mounts, but ensured more people within the Panasonic system would have less switching costs.
