Leica R9
The Leica R8 & R9 are manual focus 35 mm single-lens reflex cameras produced by the German firm Leica as the final models of their R series. Development of the R8 began in 1990: the camera was introduced at the 1996 photokina trade show, and was succeeded by the similar Leica R9 in 2002. Both can be fitted with the Digital Modul R (DMR) digital back (discontinued in 200 and used as a digital camera making them the only 35 mm SLRs to take a user-installable digital back. The R8 was the first R-series camera to have no association with Minolta, being solely a Leica design and showing a clear stylistic change compared to prior bodies. Design Industrial designer Manfred Meinzer was chiefly responsible for the R8 design, along with a team of designers largely new to Leica or drawn from outside. The R8 was intended as a clean break from the previous generation of Leica R cameras, which had been developed in cooperation with Minolta. A key design goal was to evoke the Leic ...

Leica R8 2934
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 Solms. ...

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 ...

Leica R Bayonet
The Leica R bayonet mount is a camera lens mount system introduced by Leitz in 1964. The R mount is the standard method of connecting a lens to the Leica R series of 35 mm single-lens reflex cameras. The mount is descended from those used for the Leicaflex, Leicaflex SL and Leicaflex SL2 SLR cameras, but differs in the cams used to communicate lens aperture information to the camera. 3 cam lenses are compatible with all of the Leica SLR cameras, while R-only lenses have a slightly different mount shape that will not fit on the earlier cameras. The flange focal distance between mount and film is 47 mm. On 5 March 2009, Leica announced plans to cease production of its R-Series manual focus SLR and lenses. R Mount camera bodies Leicaflex Leica R R mount lenses ;1 cam The original Leicaflex 1 cam lenses have a single sloped cam that communicates aperture setting to the camera. They can be used on later SL / SL2 and R-series cameras in stop-down metering mode only. Leica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leicaflex / SL / SL2
The Leicaflex series of high-end single-lens reflex 35 mm format film cameras were introduced by Leitz Camera in 1964. The first camera body was paired with the new R bayonet series of lenses. Three model of the cameras were sold by Leitz; the Leicaflex Standard, the Leicaflex SL and the Leicaflex SL2. Late into the market with high prices and limited range of lenses and accessories, Leicaflex sales were below expectations and production ended in 1976. However, the production of the R mount lenses continued and were paired with the new Leica R3 that was developed in cooperation with Minolta, together with the Minolta XE bodies.photoscala.de, July 2018, »R« – in the Shadow of the »M«, retrieved at 1 November 2020 (German).

Leica R4-R7
Leica R4, R5, R6, R7 were 35 mm SLR cameras manufactured by Leica between 1980 and 1997 and belonged to the manual focusing R-System, which was offered from 1965 to 2009. Following the success of the Leica R3 the company, in continuing cooperation with Minolta, produced the R4-R7 series all based on the same chassis. R4 / R4s /R4sp The Leica R4 was made from (1980 - 1986) Based on Minolta XD-7 but with Leica developed exposure metering, mirror box, and newly designed body, the R4 followed the trend setting Olympus OM-1 and was much smaller and lighter than all earlier Leica SLR cameras. Like previous models the R4 offered selective metering and viewfinder information was comprehensive showing metering / exposure mode, shutter and aperture settings, exposure level, and flash ready. The R4S (S stood for Simplified) and the R4SP (SP stood for Simplifed Professional) were simplified versions of the R4. Five exposure / metering modes were available: * Manual exposure / se ...

Cable Release
The Bulb setting (abbreviated B) on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button. The Bulb setting is distinct from shutter's Time (T) setting, which is an alternate-action mode where the shutter opens when the shutter-release button is pressed and released once, and closes when the button is actuated again. History Decades before the first flashbulbs, some box cameras and many view cameras and folding cameras came with a detachable pneumatic shutter release with a rubber bulb on the end; "Bulb" refers to the rubber shutter release bulb. Though mechanically timed exposures could also be triggered by squeezing the shutter release bulb, "Bulb" exposures then had the same momentary action as camera shutters have today, as per this description from Sears Roebuck's 1909 ''Cameras Photographic Supplies'': Around 1894 in Germany, the momentary-action setting on camera shutters made by C. A. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-sync
In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor. In cameras with mechanical (clockwork) shutters synchronization is supported by an electrical contact within the shutter mechanism, which closes the circuit at the appropriate moment in the shutter opening process. In electronic digital cameras, the mechanism is usually a programmable electronic timing circuit, which may, in some cameras, take input from a mechanical shutter contact. The flash is connected electrically to the camera either by a cable with a standardised coaxial PC (for Prontor/Compur) 3.5 mm (1/8") connector (as defined in ISO 519), or via contacts in an ''accessory mount'' (hot shoe) bracket. Faster shutter speeds are often better when there is significant ambient illumination, and flash is used to flash fill subjects that are backlit without motion ...

F Stop
In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture").Smith, Warren ''Modern Optical Engineering'', 4th Ed., 2007 McGraw-Hill Professional, p. 183. It is also known as the focal ratio, f-ratio, or f-stop, and is very important in photography. It is a dimensionless number that is a quantitative measure of lens speed; increasing the f-number is referred to as ''stopping down''. The f-number is commonly indicated using a lower-case hooked f with the format ''N'', where ''N'' is the f-number. The f-number is the reciprocal of the relative aperture (the aperture diameter divided by focal length). Notation The f-number is given by: N = \frac \ where f is the focal length, and D is the diameter of the entrance pupil (''effective aperture''). It is customary to write f-numbers preceded by "", which forms a mathematical expression of the entrance pupil diameter in t ...

Copal Shutter
The , or Copal, is a Japanese manufacturer of optical, electronic and mechanical equipment, primarily for the photographic industry. It has been a subsidiary of Nidec Corporation since 1998, and was formerly known as the Copal Corporation. The company began operation in 1946, with small-scale production of photographic shutters; these are still one of the company's best-known products. In the 1960s the company began producing the well-known Copal Square vertically travelling metal blade focal plane shutter, which was very successful and was used in cameras by many prominent manufacturers. The ''Copal Square-S'', for example used in the Konica T3s (1973-1978) and the Nikkormat FT, is very reliable. It works over a wide temperature range. The electronically controlled Copal ''Square E'' (1968) was used in the Yashica TL Electro X, the Canon EF, the Nikkormat EL. For Minolta XE and the Leica R3 the Copal-Leitz Shutter ''CLS'' was developed in 1972. For the professional Nikon F4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
