Provided are an auto focus (AF) locking unit and a photo-graphing apparatus including the AF locking unit. In particular, the AF locking unit supports a lens group barrel holder that is descended by a movement of a front barrel in an optical axis direction by using a locking lever provided with an elastic force, and the photographing apparatus includes the AF locking unit. According to an embodiment, the AF locking unit supports the lens group barrel holder including lenses in the optical axis direction by using a driving force transmitted from a motor in correspondence to movements of a cam barrel and a front barrel, and the photographing apparatus includes the AF locking unit.
