darktable focuses on providing excellent tools for raw image
development. It does a good job of supporting a large number of camera
raw formats and lenses (due to lensfun as you've discovered).

It does provide a tethering feature for remote control of the camera. I
think it may even have some stop motion features but It's a while since
i've used the tethering feature.

To me that seems like a fairly specialised area of photography
requiring specialised tools. I'm not aware of any such tools for Linux,
but then I've never really looked for them!

Regards,
Tony.
