An electronic device comprising a split camera in front and back portions, and a retaining member. The front portion of the camera includes a set of front mounting features and a light-collecting unit configured to collect light from a subject. The back portion of the camera is reversibly separable from the front portion; it includes a set of back mounting features and an imaging unit configured to image the light. The set of back mounting features is configured to contact the set of front mounting features as the front and back portions are drawn together, forming, cooperatively, a kinematic mount to hold the light-collecting and imaging units in a state of alignment. The retaining member is configured to couple the front portion to the back portion when the front and back portions are drawn together and also when the front and back portions are separated.
