Abstract:

A telephoto lens sighting apparatus. A mount couples to a hot shoe of a camera and a first sight couples to the mount. The first sight has a first gap that corresponds with a viewing aperture of a telephoto lens coupled to the camera. A second sight may be movably coupled to the camera through a sliding track and may thereby move with respect to the first sight. The second sight has a second gap, and the first gap and second gap when aligned correspond with a viewing aperture of a telephoto lens coupled to the camera. A first receiver may couple to the camera to selectively receive the first sight and a second receiver may couple to the camera to selectively receive the second sight. The first sight and second sight may each pivot to a plurality of positions and their heights may be adjusted.
