I would take the front element off my fathers binoculars, one them and put it on the front of the lens. I had a cheap 35mm SLR with a fixed lens. Or maybe older finely made older lens are simple, but elegant. Also fine optics also have no less than 12 elements. Fine lens are always F1.4 or faster, F2.4 no way. It may even be made in Germany, who ever heard of German optics. The real surprise is that this company made even useful optics. Rolli what kind of brand is that?! I may first think the lens was designed for a 35mm projector, maybe a 6cm圆cm. Below is a gallery of images captured with the setup and shared with permission from Mathieu. Sure, it's not the most elegant solution, but it got the job done. The helicoidal tube has an M42 screw mount, so all he needed to do then was find an M42 to Sony E mount adapter so the whole kit would fit on his a7 lll. Mathieu discovered the lens fit perfectly into a M52 helicoidal tube which then allowed him to vary the apparent length of the lens so he could focus at a normal range of distances. In the three minute video above Mathieu shows the lens in action and a number of photos captured in the sun that seem to have well controlled flare and low contrast.Īs the lens has no iris the aperture can’t be varied from F2.4, but based on the results he attained, that doesn't appear to be a problem. Mathieu says he found the lens without its projector in a yard sale, and paid $5 for it. The lens he used is a Rollei 90mm f/2.4 MC that would have originally been fitted to a 35mm slide projector. The company of Ernst Leitz had its origin in the Optical Institute founded by Karl Kellner in Wetzlar, Germany.In pursuit of something different Mathieu Stern, who runs the Weird Lens Museum website, has adapted an old projector lens to fit on the front of his Sony a7 lll. The earlier Leitz trade catalogues give the date of establishment as 1850 but by the early twentieth century, Leitz publications put the date at 1849. Telescopes were the main product of the early company, but in the 1850s, microscopes became the principal product. In 1855, Kellner died at age 29 of tuberculosis and his partner Friedrich Christian Belthle took over the workshop. The company became known as the Optical Institute Kellner and Belthle. In 1865, Belthle hired an engineer, Ernst Leitz (1843-1920), who became his partner a year later. Leitz took over the company upon Belthle's death in 1869, and renamed it the Optical Institute of Ernst Leitz (Optischen Institut von Ernst Leitz). With the outbreak of the Franco-Prussian War in 1870, Leitz had a rough time his first year.

Even so, he was able to ride the wave of an expanding market for microscopes.

One innovation he made was to ramp up production and quality by switching away from the slow, labor-intensive manufacturing by hand to serial manufacturing.

In 1911 Oskar Barnack (1879-1936) was hired by Ernst Leitz with the idea of designing an easily portable camera. #Ernst leitz wetzlar microscope for sale portable Max Berek (1886-1949) joined the Ernst Leitz company after he had finished his studies in mathematics and mineralogy in Berlin. He mathematically designed the first Leitz camera lens, a 50mm anastigmat. It is today known as the "UR-Leica Prototype." In 1913, Barnack invented the 35mm camera using the new lens system. In 1920, Ernst Leitz died, and his son, Ernst Leitz II (1870-1956) became the sole owner of the business.

In 1924, Ernst Leitz II decided to put Barnack's invention into production. The new 35mm cameras were branded "Leica," which was formed by a contraction of Lei(tz) Ca(mera). The first Leica cameras were put on the market in 1925. In 1930, Leica introduced the first 35mm cameras with interchangeable lenses. The branches of the Leitz companies were consolidated and renamed Ernst Leitz GmbH.ĭuring World War I, the German government forced the Leitz company to convert to war production. During World War II, however, Max Berek, the renown optical scientist at Leitz, refused to cooperate with the Nazi party. The German government stripped him of his professorship, but it was reinstated in 1946.
