Leica M4-2
The Leica M4 is a 35 mm rangefinder camera produced by Ernst Leitz GmbH. Leica M4 The M4 started production in November 1966, as the direct successor of the M3 and M2, featuring framelines for 35 mm, 50 mm, 90 mm and 135 mm lenses in a 0.72 magnification viewfinder. It has the frame counter of the M3, with automatic reset after reloading. The M4 was the last Leica rangefinder of this era to be predominantly hand-built. Three ergonomic modifications were introduced in the M4: * an articulating film advance lever, modernised self-timer and frame selection levers * an angled crank for rewinding the film that replaced the slow to use telescopic knob of the M3 * a faster loading system that does not require use of a removable spool Production of the Leica M4 ceased in 1975. An olive coloured Leica M4, originally designed for the West German Army, sold at auction in 2009 for €87,600. Leica MDa A scientific version without a viewfinder was made as the L ...

35 Mm Format
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame".

Leica M5
The Leica M5 is a 35 mm camera by Leica Camera AG, introduced in 1971. It was the first Leica rangefinder camera to feature through-the-lens (TTL) metering and the last to be made entirely in Wetzlar by hand using the traditional "adjust and fit" method. Design The M5 departed from the traditional silhouette of the Leica rangefinders, that had few changes since the M3 (1954). The height and width of the body were larger (H 84 mm x W 150 mm x D 36 mm), and the body heavier (ca. 50 g more than other M cameras). The folding film rewinding crank hides in the bottom plate. The self-timer arm and the field-of-view preselector (now on the M5 additionally with battery test function) are of the same design as the Leica M4 (1967). The M5 was the last M to feature a mechanical self-timer (duration 5–10 seconds). The M5 incorporates an improved rapid film loading spool design over the M4. The M5 has a rapid transport lever which winds the shutter and advances the film and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leica M-mount Cameras
Leica Camera AG () is a German company that manufactures cameras, optical lenses, photographic lenses, binoculars, rifle scopes and microscopes. The company was founded by Ernst Leitz in 1869 (Ernst Leitz Wetzlar), in Wetzlar, Germany. In 1986, the Leitz company changed its name to Leica, due to the fame of the Leica trade-name. The name Leica is derived from the first three letters of the founder's surname (Leitz) and the first two of the word camera: lei-ca (LEItz CAmera). At this time, Leica relocated its factory from Wetzlar to the nearby town of Solms. Leica Camera AG is 55% owned by Austrian investment firm ACM Projektentwicklung GmbH, and 45% owned by The Blackstone Group which licenses the Leica brand name from the Danaher Corporation-owned Leica Microsystems GmbH.

Through-the-lens Metering
In photography, through-the-lens metering (TTL metering) refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure ( average luminance), it can also be used to control the amount of light emitted by a flash unit connected to the camera. Description Through-the-lens metering is most often associated with single-lens reflex (SLR) cameras. In most film and digital SLRs, the light sensor(s) for exposure metering are incorporated into the pentaprism or pentamirror, the mechanism by which a SLR allows the viewfinder to see directly through the lens. As the mirror is flipped up, no light can reach there during exposure, the necessary amount of exposure needs to be determined before the actual exposure. Consequ ...

Leica M6
The Leica M6 is a rangefinder camera manufactured by Leica from 1984 to 2002 until its major reissue in 2022. The M6 combines the silhouette of the Leica M3 and Leica M4 with a modern, off-the-shutter light meter A light meter is a device used to measure the amount of light. In photography, a light meter (more correctly an exposure meter) is used to determine the proper exposure for a photograph. The meter will include either a digital or analog calcul ... with no moving parts and LED arrows in the viewfinder. Informally it is referred to as the M6 "Classic" to distinguish it from the "M6 TTL" models, and to indicate its "Classic" M3 dimensions. The top and bottom plates were made from lighter, cheaper magnesium alloy rather than the heavier machined brass of the M3 and M4. The M6 and M6 TTL are mechanical cameras; all functions save the light meter work without batteries, unlike the succeeding M7, which needs electrical power to operate properly.

Self-timer
A self timer is a device on a camera that gives a delay between pressing the shutter release and the shutter's firing. It is most commonly used to let the photographer to take a photo of themselves (often with a group of other people), hence the name. The self-timer is also used to reduce camera shake when taking photographs in low light or with long (telephoto) lenses. The timer's delay gives the photographer time to steady the camera before the shutter fires, and allows vibrations from the mirror flipping up (on SLRs) to die out. It also eliminates any photographer-induced camera motion when the shutter button is pressed. Most modern cameras with a self-timer flash a light during the countdown, emit a beeping sound, or both. These warnings generally increase in speed or intensity during the last few seconds, to warn that the shutter is about to fire. The most common delay is ten seconds. Some cameras also have a two-second and five-second settings. A few cameras provide con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motor Drive
Motor drive means a system that includes a motor. An adjustable speed motor drive means a system that includes a motor that has multiple operating speeds. A variable speed motor drive is a system that includes a motor and is continuously variable in speed. If the motor is generating electrical energy rather than using it – this could be called a generator drive but is often still referred to as a motor drive. A Variable Frequency Drive(VFD) or Variable Speed Drive(VSD) describes the electronic portion of the system that controls the speed of the motor. More generally, the term drive, describes equipment used to control the speed of machinery. Many industrial processes such as assembly lines must operate at different speeds for different products. Where process conditions demand adjustment of flow from a pump or fan, varying the speed of the drive may save energy compared with other techniques for flow control. Where speeds may be selected from several different pre-set ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leica M-mount
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. This lens mount has also been used by Epson, Ricoh, Minolta, Konica, Cosina Voigtländer, Rollei, Carl Zeiss AG and Rollei Fototechnic on some of their cameras. Overview The Leica M mount was introduced in 1954 at that year's Photokina show, with the Leica M3 as its first camera. The 'M' stands for ''Messsucher'' or rangefinder in German. This new camera abandoned the M39 lens mount in favour of a new bayonet mount. The bayonet mount allowed lenses to be changed more quickly and made the fitting more secure. Other innovations introduced by the M3 included a single window for the viewfinder (for composition) and the rangefinder (for focussing). With a double-stroke film advance lever (later models hav ...
