Leica M7
The Leica M7 is a 35 mm rangefinder camera introduced by Leica AG in 2002 as a direct successor to the M6. The electronic Leica M7 is a departure from previous mechanical designs for the M series. Details The M7 introduced auto-exposure in aperture priority mode: the user sets the aperture on the lens manually, and the camera chooses a shutter speed. Manual exposure is also available. The shutter is electronically controlled, but speeds of 1/60 and 1/125 of a second are mechanically governed if the battery fails. Unlike the M6 TTL whose "off" position only disables the meter, the M7 features a switch on the shutter release, which prevents both metering and the shutter from firing. The shutter release is redesigned with two distinct levels of pressure: the first detent locks the exposure reading, the second fires the shutter. The M7 is also the first Leica M series to support film DX encoding and exposure compensation using the dial that has been on the back of Leica cameras s ...

Rangefinder Camera
A rangefinder camera is a camera fitted with a rangefinder, typically a split-image rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus. Most varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel. Older, non-coupled rangefinder cameras display the focusing distance and require the photographer to transfer the value to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory shoe. Earlier cameras of this type had separate viewfinder and rangefinder windows; later the rangefinder was incorporated into the viewfinder. More modern designs have rangefinders coupled to the focusing mechanism so that the lens is focused correctly when the rangefinder images fuse; compare with the ...

135 Film
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 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 ...

Hot Shoe
Canon EOS 350D Hot shoe Proprietary hot shoe used by Minolta and older Sony cameras (Konica Minolta Maxxum 7D">Sony.html" ;"title="Minolta and older Sony">Minolta and older Sony cameras (Konica Minolta Maxxum 7D) A hot shoe is a mounting point on the top of a camera to attach a flash (photography), flash unit and other compatible accessories. It takes the form of an angled metal bracket surrounding a metal contact point which completes an electrical connection between camera and accessory for standard, brand-independent flash synchronization. The hot shoe is a development of the standardised "accessory shoe", with no flash contacts, formerly fitted to cameras to hold accessories such as a rangefinder, or flash connected by a cable. The dimensions of the hot shoe are defined by the International Organization for Standardization in ISO 518:2006. Details such as trigger voltage are not standardised; electrical incompatibilities are still possible between brands. Design The ...

Leica Camera
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. History From the year 1907 to the 1950s, the buildings that formed Leica factory were built on Ernst Leitz Street in Wetzlar, and remained until 1986, when the factory was moved to the city of ...

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 (photography), exposure for a photograph. The meter will include either a Di ... 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.

DX Encoding
DX (Digital indeX) encoding is an ANSI and I3A standard, originally introduced by Kodak in March 1983, for marking 135 and APS photographic film and film cartridges. It consists of several parts, a latent image DX film edge barcode on the film below the sprocket holes, a code on the cartridge used by automatic cameras, and a barcode on the cartridge read by photo-finishing machines. History In order to simplify the handling of 35 mm film in 135 format Kodak introduced the DX encoding method on 3 January 1983. In contrast to former solutions like Fuji's film speed encoding method in 1977, which was already using electrical contacts for film speed detection on 135 format cartridges, Kodak's later DX code system immediately met success in the marketplace. The first DX encoded film was the color negative film Kodacolor VR-1000 in March 1983. The first cameras to use the technology was the Konica TC-X SLR (1985), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exposure Compensation
Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image. Factors considered may include unusual lighting distribution, variations within a camera system, filters, non-standard processing, or intended underexposure or overexposure. Cinematographers may also apply exposure compensation for changes in shutter angle or film speed (as exposure index), among other factors. Many digital cameras have a display setting and possibly a physical dial whereby the photographer can set the camera to either over or under expose the subject by up to three f-stops (f-numbers) in 1/3 stop intervals. Each number on the scale (1,2,3) represents one f-stop, decreasing the exposure by one f-stop will halve the amount of light reaching the sensor. The dots in between the numbers represent 1/3 of an f-stop.Exposure Compensation"By Geoff Lawrence"/r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leica M3
The Leica M3 is a 35 mm rangefinder camera by Ernst Leitz GmbH (now Leica Camera AG), introduced in 1954. It was a new starting point for Leitz, which until then had only produced screw-mount Leica cameras that were incremental improvements to its original Leica (Ur-Leica). The M3 introduced several features to the Leica, among them the combination of viewfinder and rangefinder in one bright window, like on the Contax II, a bayonet lens mount, and rapid film advance lever. It was the most successful model of the M series, with over 220,000 units sold by the time production of the M3 model ended in 1966. It was succeeded by a number of later film M series cameras, including the Leica M-A film camera in 2014. The earliest Leica M3 pre-model that was built, sold at auction in 2009 for €72,000. In June 2019 a pre series model from 1952/1953 was sold for €360.000 at the 34th Leitz auction in Wetzlar. Mount This new bayonet mount, which has not been changed in the following h ...

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 (photography), exposure for a photograph. The meter will include either a Digital data, digital or analog calculator which displays the correct shutter speed and f-number for optimum exposure, given a certain lighting situation and film speed. Similarly, exposure meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. Light meters are used in the general field of architectural lighting design to verify proper installation and performance of a building lighting system, and in assessing the light levels for growing plants. Use in photography The earliest type of light meters were called ''Complex index of refraction, extinction meters'' and contained a numbered or lettered row of neutral density filters of increasing density.
