The M3 has an exceptionally bright viewfinder when compared to any previous or subsequent model, including the modern M9. [3] The M3 has a high magnification factor of 0.91×, which is useful in critical focusing, and especially with long lenses (subsequent Leicas would use 0.85×, 0.72× or 0.58×). "Leica goggles" of a 35mm lens.
M3 – 1954–1967 (Total 200,000 units manufactured) Introduced at the German photokina exhibition in 1954, the M3 was the first of the M series Leicas, a line that is still manufactured today, and featured the first Leica body with a bayonet-style mount for interchangeable lenses. In an advertisement from 1956, it was regarded as a "lifetime ...
A measure of the permissible distance within which an object remains in acceptable, though not perfect, focus. [11] Calculations of DOF assume that an imperfectly focused "circle of confusion" smaller than 0.20 to 0.25 mm is indistinguishable from perfect focus in an image viewed from a normal distance.
Diagram illustrating the flange focal length of an SLR–type and a mirrorless–type camera. For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the ...
The Digital Classic Camera Leica M3 is a miniature replica camera made by Minox with the outward appearance of a Leica M3 viewfinder camera. It has a digital camera processor made by Zoran. The body is made of metal, covered with leatherette. Some of the metal levers are movable but without function. The camera is very small and light.
The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses.It has been used on all the Leica M-series cameras and certain accessories (e.g. Visoflex reflex viewing attachment) up to the current film Leica M-A and digital Leica M11 cameras.
In optics and photography, hyperfocal distance is a distance from a lens beyond which all objects can be brought into an "acceptable" focus. As the hyperfocal distance is the focus distance giving the maximum depth of field, it is the most desirable distance to set the focus of a fixed-focus camera. [1]
