The lenses for the IMX219 and other mobile-use sensors were developed using materials optimized for the MTF of its 1.12 µm pixels.
M12 lenses, on the other hand, are typically designed with MTF characteristics suitable for 2–2.9 µm pixels, so replacing the lens may actually reduce sharpness.
In general, it is difficult to find C-Mount or M12 lenses specifically designed for 1.12 µm pixels, so it is necessary to use lenses designed for the HQ camera (1/2.3") with a 12-megapixel resolution.
Since the HQ camera has the same optical format and pixel count as GoPro, it is possible to find replacement M12 lenses for it.
