Miranda T (camera)
The original Miranda T 35mm SLR camera was launched by the newly established Japanese Orion Camera Co. in 1955. It is the first Japanese 35mm SLR camera to have an eyelevel Pentaprism finder. The camera was a success, and after only two years, the manufacturer changed its name to the Miranda Camera Co. The camera stayed in production for two more years while a series of new models designated model A, B, C, D, and S were introduced, based on the original camera. These comprised improvements like a faster shutter with 1/1000-second top speed, a frame counter, wind-on lever, and an Instant return mirror on model B in 1958. In addition, a rare Miranda TII with 1/1000-second top shutter speed does exist. The Miranda cameras were equipped with a double lensmount consisting of a wide 44mm internal thread and an external bayonet—the Pentax/Praktica screw mount is 42mm. The flange to film plane distance was deliberately made as short as possible to accommodate as many different makes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-lens Reflex Camera
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.

Pentaprism
A pentaprism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism. The beam reflects inside the prism ''twice'', allowing the transmission of an image through a right angle without inverting it (that is, without changing the image's handedness) as an ordinary right-angle prism or mirror would. The reflections inside the prism are not caused by total internal reflection, since the beams are incident at an angle less than the critical angle (the minimum angle for total internal reflection). Instead, the two faces are coated to provide mirror surfaces. The two opposite transmitting faces are often coated with an antireflection coating to reduce spurious reflections. The fifth face of the prism is not used optically but truncates what would otherwise be an awkward angle joining the two mirrored faces. In cameras A variant of this prism is the roof pentaprism which is commonly used in the viewfinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miranda Camera Company
The Miranda Camera Company, originally named the Orion Camera Company, manufactured cameras in Japan between and . Their first camera was the Miranda T. Many of their products were single-lens reflex cameras for 135 film (35 mm). Unlike many Japanese made cameras, Miranda did not make their own lenses and had to rely on other manufacturers to supply them. All their SLR cameras, except the dx-3, had interchangeable pentaprisms (released by moving a button or twisting the base of the film rewind knob), and a unique dual lens mount; an external bayonet mount or a 44mm thread mount within the mirror box. Unable to keep up with the increasing manufacturing automation of the larger manufacturers, and the increasingly sophisticated electronics of competing cameras, Miranda ceased producing cameras. Miranda cameras were a line of quality 35mm single lens reflexes, a range of over 30 models between first prototypes in 1953 through to the last production model in 1978. Many had ad ...

Instant Return Mirror
In photography, the single-lens reflex camera (SLR) is provided with a mirror to redirect light from the picture taking lens to the viewfinder prior to releasing the shutter for composing and focusing an image. When the shutter is released, the mirror swings up and away allowing the exposure of the photographic medium and instantly returns after the exposure. No SLR camera before 1954 had this feature, although the mirror on some early SLR cameras was entirely operated by the force exerted on the shutter release and only returned when the finger pressure was released. The Asahiflex II, released by Japanese company Asahi (Pentax) in 1954, was the world's first SLR camera with an instant return mirror.Michael R.

Lens Mount
A lens mount is an interface – mechanical and often also electrical – between a photographic camera body and a lens. It is a feature of camera systems where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex type, single lens mirrorless type or any movie camera of 16 mm or higher gauge. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements. Mount types A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock (friction lock) type. Modern still camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body. Screw-threaded mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in us ...

M42 Lens Mount
The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount, which shares the 42mm throat diameter, but differs by having a 0.75mm thread pitch.) It was first used by the East German brands VEB Zeiss Ikon in the Contax S of 1949, and KW in the Praktica of the same year. VEB Zeiss Ikon and KW were merged into the Pentacon brand in 1959, along with several other East German camera makers. M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount.The M42 mount is sometimes referred to as a "P" thread. See, e.g., Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soligor
Soligor was originally the trade mark for the American Allied Impex Corporation, used from 1956 for lenses and later cameras imported from Japan. It imported cameras from Japan and also took control of companies in Japan. Among the first products was Miranda T (camera), Miranda T camera and Soligor lenses. Soligor GmbH is a German manufacturer of photographic equipment, optics, video surveillance equipment, and personal electronics. Founded in Stuttgart in 1968 as A.I.C. Phototechnik GmbH by Allied Impex Corporation (USA), the company changed its official name in 1993 to match the brand name used on its optical products. Most commonly encountered products were manufactured in Japan (to quite a reasonable standard-many by Tokina) under the Soligor brand, as well as Miranda Camera Company, Miranda (which was acquired by Allied Impex in the 1960s). The company also seems to have had an association with Vivitar (the T4 interchangeable mount, for instance). The company is currently ...

History Of The Single-lens Reflex Camera
The history of the single-lens reflex camera (SLR) begins with the use of a reflex mirror in a camera obscura described in 1676, but it took a long time for the design to succeed for photographic cameras. The first patent was granted in 1861, and the first cameras were produced in 1884, but while elegantly simple in concept, they were very complex in practice. One by one these complexities were overcome as optical and mechanical technology advanced, and in the 1960s the SLR camera became the preferred design for many high-end camera formats. The advent of digital point-and-shoot cameras in the 1990s through the 2010s with LCD viewfinder displays reduced the appeal of the SLR for the low end of the market. The mirrorless interchangeable-lens camera is increasingly challenging the mid-price range market. But the SLR remains the camera design of choice for most professional and ambitious amateur photographers. Early large and medium format SLRs The photographic single-lens reflex ...
