Rollei 35 RF
The Rollei 35 RF is a version of the Cosina Voigtländer Bessa R2 marketed by Rollei Fototechnic, but manufactured by Cosina, and released in 2002. Like the Bessa R2, the Rollei 35 RF has a Leica M-mount and a metal focal-plane shutter. Its TTL exposure meter requires batteries, but batteries are not otherwise needed. Shutter speeds range from 1 to 1/2000 s and bulb (B), with flash sync at 1/125 s on hot-shoe or PC terminal. Upon release, the most obvious differences from the R2 were the higher price and the slightly different appearance: more silver, and more prominent branding. On the technical side, the shutter speed knob and the grip on the body are slightly redesigned and the framelines are for 40, 50, and 80 mm. Because of its high price tag and similarity to other contemporary Cosina products, it was treated without much fanfare during its original release. Nowadays it remains a popular Bessa camera for people who wear glasses and primarily use a 40 mm l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bessa R2
The Bessa family of cameras was manufactured in Japan by Cosina as a revival of the Voigtländer brand name. All the Cosina Voigtländer Bessa models have a double focal-plane shutter with two sets of curtains to prevent damage by the sun. Shutter speeds range from 1 to 1/2000 s and bulb (B), with flash sync at 1/125 s on hot-shoe or PC terminal. They all have TTL exposure metering, and manual exposure; the recent ''R2A'' and ''R3A'' also have an aperture priority automatic mode. Bessa-L and Bessa-T (finderless) The first model was the Bessa-L, introduced in 1999. This was a finderless body with a Leica screw mount. It was introduced with a range of Voigtländer 39 mm screw lenses that were quite inexpensive and said to be of excellent quality. It could of course mount all the wide variety of 39 mm screw lenses by manufacturers as diverse as Leica, Canon, Nikon and even cheaper but often excellent Soviet lenses. The ''Bessa-L'' was mostly intended to be used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rollei Fototechnic
Rollei () was a German manufacturer of optical instruments founded in 1920 by and in Braunschweig, Lower Saxony, and maker of the Rolleiflex and Rolleicord series of cameras. Later products included specialty and nostalgic type films for the photo hobbyist market. Originally named ''Werkstatt für Feinmechanik und Optik, Franke & Heidecke'', the company renamed into ''Rollei-Werke Franke & Heidecke GmbH'' in 1972, ''Rollei-Werke Franke & Heidecke GmbH & Co. KG'', in 1979, and ''Rollei Fototechnic GmbH & Co. KG'' in 1981. After being purchased in 1995 by Samsung Techwin, part of the South Korean Samsung Group, it was sold back to its internal management in 1999.

Cosina
is a manufacturer of high-end optical glass, optical precision equipment, cameras, video and electronic related equipment, based in Nakano, Nagano Prefecture, Japan. History Cosina is the successor to Nikō (or "Nikoh"), a company set up as a lens processing factory in February 1959, which was a pioneer in optical polishing and lens grinding in Japan. In 1966, it also started to manufacture 35 mm compact cameras and 8 mm cine cameras, and a year later started the manufacture of 35mm film SLR cameras; in 1968 it started a glass melting factory. Nikō changed its name to Cosina in 1973. (The first part of the name is a reference to the Koshi area within Nakano, where the founder came from; while the 'Na' represents Nakano.) The name Cosina has previously appeared on compact and SLR cameras for 135 film. The CS-2 and CS-3 SLRs were introduced in 1978, followed in 1980 by the CT-1, CT-7 (the world's first all—push-button SLR), CT-10 and CT-20, the CT-1G in 1982 and th ...

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 ...

Focal-plane Shutter
In camera design, a focal-plane shutter (FPS) is a type of photographic shutter that is positioned immediately in front of the focal plane of the camera, that is, right in front of the photographic film or image sensor. Two-curtain shutters The traditional type of focal-plane shutter in 35 mm cameras, pioneered by Leitz for use in its Leica cameras, uses two shutter curtains, made of opaque rubberised fabric, that run horizontally across the film plane. For slower shutter speeds, the first curtain opens (usually) from right to left, and after the required time with the shutter open, the second curtain closes the aperture in the same direction. When the shutter is cocked again the shutter curtains are moved back to their starting positions, ready to be released. Focal-plane shutter at low speed ''Figure 1:'' The black rectangle represents the frame aperture through which the exposure is made. It is currently covered by the first shutter curtain, shown in red. The se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash 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 ...

Shutter Speed
In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter (photography), shutter is open) when taking a photograph. The amount of light that reaches the Photographic film, film or image sensor is proportional to the exposure time. of a second will let half as much light in as . Introduction The camera's shutter speed, the lens's aperture or f-stop, and the scene's luminance together determine the amount of light that reaches the film or sensor (the exposure (photography), exposure). Exposure value (EV) is a quantity that accounts for the shutter speed and the f-number. Once the sensitivity to light of the recording surface (either film or sensor) is set in numbers expressed in "Film speed#ISO, ISOs" (ex: 200 ISO, 400 ISO), the light emitted by the scene photographed can be controlled through aperture and shutter-speed to match the film or sensor sensitivity ...

Rollei 35
The Rollei 35 is a 35mm miniature viewfinder camera built by Rollei. The original Rollei 35, when introduced at photokina in 1966, was the smallest existing 135 film camera. The Rollei 35 series remains one of the smallest 35 mm cameras after the Minolta TC-1 and Minox 35. In 30 years, about 2 million Rollei 35 series cameras were manufactured. The Rollei 35 was manufactured by DHW Fototechnik up to 2015, the successor of Franke & Heidecke as small-batch production. The last version is the ''Rollei 35 Classic'', an updated ''Rollei 35 SE''. Technical development Preliminary thoughts In about 1960, when the first subminiature cameras for 16 mm film came to market, Heinz Waaske, chief engineer of German camera maker Wirgin, proposed that the purchasers of the 16 mm subminiature cameras, or even the half-frame Olympus Pen 35 mm cameras, were motivated not by the tiny film format but the size of the cameras. After having already engineered and designed the 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
