Founding
The business recalls its roots to Swiss photographer who worked in Marseille from 1865 to 1878. In 1879 and 1892 Koch also established two family-owned photography studios in Schaffhausen. Koch worked as a portrait, landscape and alpine photographer and was considered one of the first Swiss champions of alpine photography. From 1894 until his death in 1897, Koch was also president of the Swiss Photographers Association. His son Hans-Carl, expanded the family-owned photography studios to include from 1911 photographic retailing. In 1947, the grandson of Koch senior—Carl Hans—a graduate photographer and photographic salesman, took over the family business on the early death of his father Hans-Carl, and founded the following year the Sinar company. Dissatisfied with the limited or imprecise nature of wooden view cameras (e.g. the large Kodak 3 and similar, and the popular Graphlex Graphic Graphlok series) and the limitations of technical (e.g.,P-series
The Sinar P, introduced in 1970, had asymmetric tilts and swings, as opposed to the traditional center or base tilts. This permitted rapid and precise settings without losing sharpness on the axis. The P series also introduced features such as self-arresting rack and pinion gearing and a precision-engineered quick format change system that allows the photographer to switch between 4x5/5x7/8x10 formats quickly without having to fully disassemble the rear standard. This was accomplished by using a common rear standard bearer and unlocking a single knob to switch among the various format frames. Another new feature implemented in the P series was the Sinar system of calculating swings and tilts as well as the Sinar depth of field calculator. A key feature of the Sinar P system, particularly in the domain of scientific and industrial photography, is the precise machine tolerances that are part of the fittings and movements.F-series
The F series was the light-weight version ("F" for "Field"), offering less refined features than the P series. The difference in weight is significant: the Sinar F 4x5 weighs about 3.3 kg and the Sinar P 4x5 weighs about 5.9 kg. The original Sinar F is easily identified by a brushed aluminum monorail and other aluminum accents, while the Sinar F1, F2, and F3 models were made of the same materials, but painted black. The Sinar F also has hard plastic knobs, versus the rubber-coated knobs of the F1 and F2. The Sinar F and F1 models have a clip-on front standard (lens standard) that does not fully enclose the monorail. The advantage is that this standard can easily be removed from the rail by loosening the clamp and lifting straight up, unlike the rear standard, and it is somewhat lighter weight. The disadvantage of this design is that the rail clamping mechanism is susceptible to breakage if over-tightened. The Sinar F2 and F3 models have a different front standard, which completely encloses the rail and also provides a geared focus adjustment, similar to the rear rail clamp on all Sinar F models. The correct F2 standard can easily be identified as it is a mirror image of the rear standard. The earlier F/F1 front standard has a low-profile metal hinge below the rail. The F2 and F3 models also came standard with a light-metering back, while this was an option for the F and F1 models. The F3 model is a digital/analog model that supports a variety of Sinar digital lenses and digital backs.Accessories
Sinar has manufactured many accessories since its establishment: A swing-out filter holder that allows the photographer to use a polarizing filter as well as 4x4 inch gel filters. A 4x5 reflex attachment that employed an adjustable mirror for the best possible viewing of the image. Adapters (now discontinued) were made by Sinar to adapt this viewer to various other view camera makes such asGallery
