Leitz microscopes improved on other models of their day in several ways, including lighting and optics, particularly with orthoscopic eyepieces. The microscopes were produced for biomedical as well as industrial purposes, including mineralogy. Consulting with his clients, he continued to refine the microscopes to their needs.
Leitz introduced serial production, raising sales volume rapidly after 1871. Initially, Leitz was a part shareholder of the business (in 1865), but took over as sole owner in 1869 and continued it under his own name. He was trained as an instrument maker for physical and chemical apparatus and had several years' experience making watches in Switzerland.
(1843–1920) from Baden arrived at Wetzlar in 1864 and entered service at the Optisches Institut. Following his early death on, his widow continued the business he had left behind, the "Optisches Institut" (optical institute). The ocular was capable of rendering an image with the correct perspective, free of the distortions typical of other microscopes at that time. 1922.Perea-Borobio CollectionĬarl Kellner, mechanic and self-taught mathematician, published his treatise Das orthoskopische Ocular, eine neu erfundene achromatische Linsencombination ( The orthoscopic ocular, a newly invented achromatic lens combination) in 1849, describing a new optical formula he had developed. For example, you can give your films for development at most drugstores.Leitz compound monocular microscope. The C-41 films are offered by most photo labs. The colour film is processed in the C-41 development process. Beautiful 35mm films for color or black and white shots are the Kodak Gold 200 ( eBay / Amazon) and the Ilford FP4 Plus ( eBay / Amazon). These are still easy to get today and are still being developed. In the Leica CL, cartridges are exposed with 35mm film. The use of an external flash is possible via the hot shoe. The Leica CL has a bulb mode, the shortest exposure time is 1/1000 second.
The light meter is designed for film shooting with a sensitivity from ISO 25 to ISO 1600. The “spot” is located in the middle of the lens. Measurements are taken using a measuring cell located on a swivel arm, which is pivoted between shutter curtain and lens for each shot. The built-in light meter makes it slightly easier to find the correct settings. This has the advantage that you can make the adjustment without having to take the camera off your face. This is not, as with most cameras, on the top of the camera, but in the right (from the photographer’s point of view) corner of the front. The placement of the setting wheel for the exposure time is striking. He can set the aperture, focus and exposure time according to his wishes.
This consists of a number between 0 and 500 and a letter (L-E-I-C-A).Īs most Leica M cameras know and appreciate, the photographer has full control over the camera.
These copies can be recognized by the “50 years” notch on the front and the code on the back.
On the occasion of Leitz’s 50th anniversary, there was also a limited edition of 3500. There are copies with the imprints “Leica CL”, “Leitz-Minolta CL” and “Minolta CL”. The Leica CL was produced under various names. Although the number of units produced was higher than many other models in Leica history, speculations were being made that the professional segment would not be cannibalized by the Leica CL.
However, the 35 mm camera was not a great success in Leica’s eyes after just three years, the plugs were pulled during production. The latter should be achieved among other things by the lower production costs, for this reason the camera was not built in Germany by Leitz, but by Minolta in Japan. The amateur market should be convinced above all by the compactness of the camera and the lower price compared to the other Leicas. The compact viewfinder camera was intended to reach a customer segment that was not prepared to invest in a “Professional Leica”, but still wanted a high-quality camera. The first visible result of this cooperation was the presentation of the Leica CL in 1973. The history of the camera begins in the 70s when the German Leitz and the Japanese company Minolta signed a cooperation agreement.
