The eleventh Tales discussed a large-aperture, super telephoto lens NIKKOR-H 300mm f/2.8 made exclusively for news photographers. In the Tale Thirteen, I discuss about the Reflex-Nikkor 500mm f/8 (New) which will be more familiar to amateur photographers within super telephoto lenses.
As you may know, the ancestor of the Reflex lenses (reflecting telephoto lenses) is a reflecting telescope for astronomical observation. The history of the reflecting telescope goes back to the second half of the seventeenth century when NEWTON (Isaac NEWTON (1642-1727)) and Cassegrain (Cassegrain JACQUES (1625-1712)) participated actively.
Actually, an objective lens including a photographic lens forms an image by using the effect of refraction of the lens. However, the longer the focal length, the bigger the size of the lens and, in particular, the more difficult to correct chromatic aberration. It was the reflex lens that applied the effect of reflection of a mirror to solve the two problems.
