Not quite true. Gun cameras in WW2 were normally fitted in a location, and aligned, to allow the lens to 'see' the target, and could be set at a different angle to the gun sight, allowing for paralax.
For example, the Hurricane Mk1 had the camera in the starboard wing leading edge, outboard of the prop arc, the Spitfire had the camera in the port or starboard wing root, depending on Marque, with the Mustang having a similar mount, whilst the Typhoon had the camera in the lower engine nacelle on the starboard side.
Regardless of the mounting position, the camera and lens were aligned to converge on the line of the center line axis of the aircraft concerned, at a given distance, perhaps 200 or 300 yards.
Later in the war, some German fighters had the camera 'shooting' through the gun sight, via a prism arrangement.
