![]() ![]() That was possible exactly because the f/11 aperture that was offered on those cameras was just enough for daylight pictures. Those are cameras that rescued the simple meniscus lens, just one glass concave/convex, having a front diaphragm. It is true that in that branch, it is certainly impossible not to mention also the synchronous appearance of popular roll film box cameras, mostly from Kodak, like the Brownie #2 (on the left). With lenses like the Dagor cameras could be designed exclusively for its native image and focusing dimensions. Combined with silver gelatin, much faster than collodion, the anastigmats all purpose lenses opened a new path for high quality image making, the possibility of a so far unimagined way: hand-held photography. The lens board should be larger and also bellows extension should be more flexible. Before that, all cameras should be able to accommodate different lenses. The importance of a general purpose lens, really capable of fulfilling a great number of situations, is that it allowed the concept of a one lens camera. The first ones were fast lenses, most of them Petzval type having an angle of view around 35º, and the latter, for landscapes, were short lenses with very dim images offering apertures not larger than f/11 or f/16 and angle of vision going up to 90º. Before that, the market was mostly split between Portrait and Landscape lenses. Some Rapid Rectilinears bore already this reputation but it was quickly transferred to the anastigmats. With the anastigmats it was definitely created the category of general purpose high quality lenses. ![]() The design was licensed to many other lens makers. The name Dagor was adopted only in 1904 as a short for Goerz Doppel Anastigmat. By 1895 some 30.000 had been already sold. That was the beginning of a huge success. Only four years old, Goerz was producing a Rapid Rectilinear lens called Lynkeioskop, one of the best RR versions. So Emil took it to the also very young firm Goerz in Berlin. Zeiss was not interested, maybe because two years earlier they had launched their own anastigmats. It was in 1892 that a mathematician Emil von Hoegh, 27 years old, proposed to Zeiss this double anastigmat consisting of two triplets symmetrically arranged around the diaphragm. ![]() More than one hundred years after its introduction the Dagor is still a very usable lens. This is one of the most accomplished lens design ever. ![]()
