A detailed review and historical documentation of the Kilfitt Makro-Kilar 40mm standard prime lens in f 3.5 and f 2.8 specification.
In December 1955, Popular Photography Magazine stated:
"WHAT'S YOUR DREAM lens? A needle sharp f/1 which you could use for wide-angle, normal and telephoto shots at will? All this in one neat package of optical glass which you could focus on a bug at two inches or a mountain at infinity-with generous depth of field at both extremes? This lens hasn't been designed yet, but the closest thing to it is the new, compact, f/3.5, 40mm Makro-Kilar which will fit most popular 35mm single-lens reflex cameras accepting interchangeable lenses."
Released some 70 years ago, Kilfitt Makro lenses are historically significant for being the first commercially available fully integrated macro lens, for 35mm SLR cameras.
Revolutionary for their time, Kilfitt lenses are today renowned among collectors and connoisseurs, for their unique rendering capabilities, fine tactility, and faceted functionality.
