It also has a wonderful following among the knowledgeable. If the lens is truly a 2 element design, part of te successful imaging quality of the lens is due to the limited air to air spacing.. Each lens to air space acts as a parial mirror, causing loss of contrast and reducing imaging accuracy. The succes to some extent, is due to its very simple design. But aren't the Telyt 400s simple cemented doublets with no internal glass-air surfaces? Or is that what you were getting at, Frank?
