The present disclosure relates to a surgical microscope system and a microscope camera adapter that enable various types of adjustment in a camera adapter connecting the cameras that capture a three-dimensional image, with right and left cameras simultaneously. Of respective right and left lens groups that constitute respective focus lenses, right and left lenses between lenses closest to a side of an objective lens and lenses closest to sides of eye lenses are simultaneously moved by the same distance according to a setting value, by which focus is adjusted. The present invention can be applied to a surgical microscope system.

Provided is an imaging apparatus capable of continuously imaging a natural video even though brightness is changed. In an imaging apparatus in which an exposure condition is set based on a characteristic of a transmittance control element, a first exposure condition range is calculated based on photometry of the imaging apparatus. Determination is made whether or not the calculated first exposure condition range is included in a second exposure condition range where a control range acquired by the transmittance control element is applicable. In a case where the calculated first exposure condition range is not included in the second exposure condition range, the exposure condition of the imaging apparatus is changed such that the first exposure condition range is included in the second exposure condition range.

An optical imaging apparatus capable of focusing is provided. The apparatus includes a lens assembly and an imaging sensing component. The lens group includes a stabilization component and a focusing component. The stabilization component has an optical axis and includes a first optical lens group and a driving element. The driving element is configured to drive the first optical lens group to move on a plane perpendicular to the optical axis or to rotate around the optical axis. The focusing component is fixed to the stabilization component and includes a second optical lens group. The second optical lens group is aligned with the optical axis. The image sensing component is fixed to one end of the lens group and is aligned with the optical axis.

An electronic viewfinder unit includes a finder unit and a base member. The finder unit includes a display unit, an eyepiece portion, and a lens holding member holding a lens that guides a light flux emitted from the display unit to the eyepiece portion. The base member includes a guide member configured to guide the electronic viewfinder unit to a housed state and a protruding state. The base member includes a holding portion and a turning member. The holding portion is provided with a first holding member and a second holding member that face each other with an optical axis of the lens in between. The turning member has one end held by the first holding member and another end held by the second holding member, and is turnable about an axis orthogonal to the optical axis of the lens.

A lens drive device comprises: a fixing part disposed away from the movable part; a cover for covering the movable part in the direction of an optical axis; and suspension wires for supporting the movable part relative to the fixing part, one ends of the suspension wires being secured to the fixing part and the other ends being secured to the movable part. The movable part is configured so as to be provided with: a damper material disposed so as to come in contact with the suspension wires; a stopper protrusion provided near a portion of the light-receiving-side surface where the other ends of the suspension wires are secured, the tip end of the stopper protrusion facing the inner surface of the cover in the direction of the optical axis; and a flow-stopper part stopping a flow of the damper flowing.
