June Learn how and when to remove this template message From the year to the s, the buildings that formed Leica factory were built on Ernst Leitz Street Wetzlar and remained untilwhen the factory was moved to the city of Solms.Dating: 20s Vs. 30s
The Wetzlar factory was located on the opposite side of the administrative building of and formed a special urban architecture; It is upstream from the slope of Kalsmunt and forms a structurally attractive graduation from the skyscrapers to the ruins of Kalsmunt Castle.
Already in the last decades of the 19th century, Ernst Leitz In the first years, residential buildings and workshops on the Laufdorfer Weg were still sufficient. It was in the turn of the century, when the production of optical devices expanded so much that it originated the first skyscrapers in the city of Wetzlar.
The first plans of the architect Jean Schmidt in show a brick building on a stone base, which was covered by a sloping roof and a slate roof. The four-story building is divided into six groups of windows, each of which has three windows. Narrow wall patterns and lightly embedded parapets summarize the three lowest floors. The fourth floor is visually separated from the lower part of the building by a very distant cornice.
On either side of the central building there was a hip roof that had high ceilings. The mansard's floor expanded as production and workers also increased.
Only a few years later, Leitz again demanded the construction of a tall building. After the planning of Jean Schmidt, contractor Robert Schneider built a four-story building in In the ten-axis building, similar to the oldest skyscraper, the lower levels are grouped by pilasters. The space between the two skyscrapers which originally had been provided with subsequent buildings had to be closed by another building in the early thirties.

Once again, it was Jean Schmidt, who prepared the plans for a first seven-story skyscraper. Inthe architect presented a completely revised plan. The plan was now made up of eight floors for Leica production. It was possible to access all the floors through two stairs. The government of the city and the district finally approved a construction of eight floors with a loggia like ninth floor, that later was closed. Due to the urban landscape that characterized the size of the building, the planning of the district government was initially rejected because of a simple and unsatisfactory exterior design.
Even so, the building was built in between the two oldest skyscrapers.

Inwest of the skyscraper ofa skyscraper of similar construction with nine floors was added. Intended as a compact camera for landscape photographyparticularly during mountain hikes, the Leica was the first practical 35 mm camera that used standard cinema 35 mm film. The Leica had several model iterations, and inBarnack convinced his boss, Ernst Leitz II, to make a preproduction series of 31 cameras for the factory and outside photographers to test.
Though the prototypes received mixed reception, Ernst Leitz decided in to produce the camera. Barnack conceived the Leica as a small camera that produced a small negative. To make large photos by enlargement, the "small negative, large picture" concept requires that the camera have high quality lenses that could create well-defined negatives.
Barnack resorted to a Leitz Mikro-Summar 1: The lens has five elements in three groups—the third group being three cemented elements—and was initially named the Leitz Anastigmat. Unlike other triplets, the Leitz Anastigmat has the diaphragm between the first and second elements.
The third group was simplified to two cemented elements, which was easier and cheaper to make. The first of these, Hektor, gave his name to a series of Leica lenses, and the name of the second appeared in the SummaREX.
It is now a rare collector's item. This model has a separate viewfinder showing a reduced image and rangefinder. Depth Of Field scale from Fujifilm. Depth - Distance between front and back. Distance from viewer and object.
The name is obviously derived from the earlier and slower "Elmar" designation. Focus, in - Sharp and clear in appearance. In Latin the word focus meant fireplace or hearth. The German astronomer Johannes Kepler first recorded the word in this sense in Nobody uses that measurement, except those who construct lenses!
For users of lenses, focal length refers to how wide the lens sees. There are many guesses how this name came about, a popular one being that the "summi" came from "summit" summit means the highest point of a hill or mountain; the highest attainable level of achievement while the "cron" came from "chroma" ie. The name Summi cron was used because the lens used Crown glass for the first time, which Leitz bought from Chance Brothers in England. Apparently they were originally going to use "LECA", but another camera company already used a similar name in France, so they inserted the 'i' to prevent any confusion.
Lens - A piece of glass or similarly transparent material like water or plastic.

It has a shape so that it can direct light rays. Light makes objects visible by reflecting off of them, and in photography that reflecting off of subjects is what creates textures, shapes, colors and luminance. Light in its natural form emanating from the sun also gives life to plants and living things, and makes most people happier. So far, nobody has been able to determine exactly what light is. Read more about light in my book Finding the Magic of Light.
But if you grew up with inches, feet and yards, you may have had a hard time grasping what a 50mm lens was. But as lenses were designed first in Europe, the metric system with centimeters and millimeters was used to describe lenses.
Leica SL with mm and mm R Lens: Leica Talk Forum: Digital Photography Review
The reason a 50mm lens is a 50mm lens is that there is 50mm from the focus plane the film or sensor to the center of focus inside the lens. When photography was a young subject, it was engineers who made it all, and the users were expected to understand. This is used in tele lenese lenes where blurring motion of the camera from inevitable vibrations are adjusted by the lens. Here the problem of "motion blur" is currected electronically after, which might lead to image degradation.
However, the larger the sensor resolution, the less one will notice small 'degradation'. Also, selective focus foreground and background out of focus can change the perception of perspective also see Three-dimensional. A 50mm lens is the one closest to the perspective and enlargement ratio of the human eye.
