At least the new pocket-Canon’s weird lensmount does have an adapter for their standard lens family.
(Though affixing this postage stamp of a camera to the back of one of their high-end telephoto lenses would indeed look rather out-of-scale. “I see the lens; where’s the camera?” – and indeed, affixing any of the main family of lenses to it defeats some of its size advantages.)
It’s a sorta interesting compromise, though, as a secondary/stopgap camera.
