Leica M1

The Leica M1 is a 35 mm camera by Leica Camera AG, introduced in 1959. The M1 has no rangefinder, but a parallax-corrected viewfinder with frames for 35 and 50mm permanently displayed. 9431 were made.

The M1 was the cheapest and simplest Leica M body. As such, it was suitable either as a low-budget general purpose camera, or as an interface to other instruments, like the Visoflex, or scientific instruments (telescopes, microscopes, etc.).

Several similar models were made in parallel with later iterations of the Leica M family:

Metadata

Metadata is "data that provides information about other data". Two types of metadata exist: structural metadata and descriptive metadata. Structural metadata is data about the containers of data. Descriptive metadata uses individual instances of application data or the data content.

Metadata was traditionally in the card catalogs of libraries. As information has become increasingly digital, metadata is also used to describe digital data using metadata standards specific to a particular discipline. Describing the contents and context of data or data files increases their usefulness. For example, a web page may include metadata specifying what language the page is written in, what tools were used to create it, and where to find more information about the subject; this metadata can automatically improve the reader's experience.

The main purpose of metadata is to facilitate in the discovery of relevant information, more often classified as resource discovery. Metadata also helps organize electronic resources, provide digital identification, and helps support archiving and preservation of the resource. Metadata assists in resource discovery by "allowing resources to be found by relevant criteria, identifying resources, bringing similar resources together, distinguishing dissimilar resources, and giving location information."

Leica Standard

The Leica Standard, Model E was the fourth version of the original 35 mm Leica camera to be launched from Ernst Leitz in Wetzlar, Germany. The concept was conceived by their employee Oskar Barnack in 1913. Production of the camera began in 1925 but it wasn't until the end of the decade that it was perfected and full-scale production was established.

History

The Leica Standard, Model E was the fourth version of the original 35 mm Leica camera to be launched from Ernst Leitz in Wetzlar, Germany. The concept was conceived by their employee Oskar Barnack in 1913 at which time two prototypes were built. However, it was not until 1924 that Leitz decided to go ahead with the concept and production began the following year. By the end of the decade, the camera had been perfected and full-scale production was established.

The Leica Standard was introduced as a basic model by Ernst Leitz, Wetzlar in October 1932. The camera was in production at the same time as the Leica II and Leica III models that have coupled rangefinders; the latter also has the faster speed of 1/1000 sec. It has a standardised lens mount with distance from film plane to lens flange fixed to 28.8 mm, a Leitz standard. This feature was first seen on late Leica I model C cameras in 1931, and all Leica II, Model D from 1932, identified by a "0" (zero) stamped on the lens mount flange at the top, to indicate the implementation of the standard, a practice that was continued for some time. It is found on early Leica Standards as well. On the back of these models there is a hole covered by a black plug, presumably for back focus calibration. The original lens for the Leica Standard when introduced was the Leitz Elmar 1:3,5 F=50mm in a collapsible nickel-plated focusing mount with infinity catch.
