Cosina Voigtländer Bessa-R
The Bessa family of cameras was manufactured in Japan by Cosina as a revival of the Voigtländer brand name between 1999 and 2015. Models Every Cosina Voigtländer Bessa camera has a double focal-plane shutter with two sets of curtains to prevent damage by the sun. Shutter speeds range from 1 to s and bulb (B), with flash sync at s on hot-shoe or PC terminal. They all have TTL exposure metering, and manual exposure controls; models with an "A" suffix (e.g., R2A, R3A, R4A) 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, and operation and specifications similar to SLRs built by Cosina for other brands, such as the Nikon FM10, Olympus OM-2000, and Ricoh KR-5. 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 va ...

Voigtländer Bessa R3a Img 1386
Voigtländer () was a significant long-established company within the optics and photographic industry, headquartered in Braunschweig, Germany, and today continues as a trademark for a range of photographic products. History Voigtländer was founded in Vienna, Archduchy of Austria, in 1756, by . Voigtländer produced mathematical instruments, precision mechanical products, optical instruments, including optical measuring instruments and opera glasses, and is the oldest name in cameras. Early beginnings Johann Christoph Voigtländer (November 19, 1732 in Leipzig – June 27, 1797 in Vienna), the son of a carpenter, came to Prague in 1755, and to Vienna in the same year, and worked from 1757 to 1762 in the workshop of Meinicke, who produced mathematical instruments. Through Johann Voigtländer's skilful achievements, the Minister of State of the Habsburg monarchy—Wenzel Anton, Prince of Kaunitz-Rietberg, Prince Wenzel von Kaunitz, drew attention to Voigtländer and Empress Ma ...

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 lens. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Co ...

Viewfinder
In photography, a viewfinder is a device on a camera that a photographer uses to determine exactly where the camera is pointed, and approximately how much of that view will be photographed. A viewfinder can be mechanical (indicating only direction and approximate view), with simple optical components, with precision optics and optical functions, or a digital accessory device used with digital cameras. View camera, View camera These cameras had no separate viewfinder. The exact image (although upside-down and reversed left-right) was viewed on a ground glass installed either in a replaceable plateholder, or in a spring back where springs hold the ground glass at the focus plane until a photographic plateholder is slid in front of it. Spring backs usually had a flip-up cover protecting the ground glass. A black focusing cloth was used with larger models. Mechanical finders Later referred to as "sports finders", for many sports and newspaper applications optical viewfinders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leica Screw Mount
The M39 lens mount is a screw thread mounting system for attaching lenses to 35 mm cameras, primarily rangefinder (RF) Leicas. It is also the most common mount for Photographic enlarger lenses. True Leica Thread-Mount (LTM) is 39 mm in diameter and has a thread of 26 turns-per-inch or threads-per-inch (tpi) (approximately 0.977 mm pitch) of Whitworth thread form. Whitworth threads were then the norm in microscope manufacture. The Royal Microscopical Society (RMS) thread, also known as ''society thread'', is a special 0.8" diameter x 36 tpi Whitworth thread used for microscope objective lenses and Leitz was a major manufacturer of microscopes, so the tooling at the plant was already set up to produce the Whitworth thread form. The Soviets in the 1930s produced their early FED cameras in M39×1 (39 mm by 1 mm DIN thread). Early Canon cameras also used a different M39 × 24 tpi thread mount, called "J-mount". True LTM lenses have a flange focal distance of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
