The original Planar is a six-element symmetrical designed by Paul Rudolph (physicist) at Carl Zeiss in 1896. While very sharp, the lens suffered from flare due to the large number of air-to-glass surfaces. Thus, it was temporarily pushed aside in favour of the Tessar, a simpler, four elements design. While it delivered slightly inferior image quality, the Tessar was much less susceptible to flare due to its fewer air-to-glass surfaces. In the 1950s, when high-quality lens coatings became available, the Planar was taken up again and its flare problems were solved. This enabled Planar-formula lenses to dominate the normal (50mm) to short tele lens category. Photograph of NASA lunar lander containing lens flare. ...
