Abstract
An image sensing apparatus in which a plurality of lens units can be exchanged and attached. The image sensing apparatus includes an acquiring unit configured to acquire, from an attached lens unit, lens information including at least an exit pupil distance of the lens unit, an image sensor including a plurality of pixels for converting incident light into electrical charges corresponding to the amount of incident light, a shutter unit configured to shield the image sensor from light, a reset unit configured to sequentially reset the pixels of the image sensor in a traveling direction of the shutter unit prior to starting to shield the image sensor from light using the shutter unit, and a control unit configured to control a timing for resetting the pixels, based on the acquired lens information, where photography is prohibited when the lens information fails to be acquired.
