The described lens assembly for use with a camera having a camera body includes a tilt assembly portion configured to allow pivotal movement of the lens body relative to the camera body. The lens assembly further includes a focus assembly configured to axially adjust a position of a removable optic assembly mounted to the focus assembly relative to the lens body to control focus of the lens assembly when the optic assembly is installed in the lens body. The lens body and focus assembly may be structured to remain coupled to the camera body after the optic assembly is removed from the focus assembly.
