Since I have some Canon EF-s lenses for my DSLR cameras and the HQ camera has the facility to change lenses, I did some experiments to see if the combination makes sense. So I got a HQ camera with the 6mm and 16mm lens, a Raspberry 3B+ from my RPi stock and 3d printed the Canon EF to C mount adapter. Some experiments, not a professional photographic review, just getting to know what can be achieved with this combination.
The short story: it does make sense, though manual focussing is a thing with the HQ camera. Oh, and a long camera cable is handy!
