Zuiko
Zuiko ( ja, ズイコー, italic=default or ja, 瑞光, italic=default, label=none) is a brand of optical lenses made by Olympus Corporation that was used up to and into the Four Thirds system era. The name Zuiko ( ja, 瑞光, italic=default, label=none) means 'Light of the Gods', using a character from the Mizuho Optic Research Laboratory ( ja, 瑞穂光学研究所, italic=default, label=none), where the lens was developed, and a character from Takachiho Corporation ( ja, 高千穂製作所, italic=default, label=none), which would eventually become the Olympus Corporation. With the introduction of the Micro Four Thirds system in 2008, new lenses for that system started to be branded as ''M.Zuiko Digital''. Optical formula nomenclature For lenses manufactured until approximately 1972, the number of optical elements of the lens, angle of view, and diaphragm operation could be distinguished by the markings engraved on the lens. The engraving dropped the number of elements wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Thirds System
The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) and mirrorless camera design and development. The system provides a standard that, with digital cameras and lenses available from multiple manufacturers, allows for the interchange of lenses and bodies from different manufacturers. seems to cover the standard. Proponents describe it as an open standard, but companies may use it only under a non-disclosure agreement. Unlike older single-lens reflex (SLR) systems, Four Thirds was designed from the start to be entirely digital. Many lenses are extensively computerised, to the point that Olympus offers firmware updates for many of them. Lens design has been tailored to the requirements of digital sensors, most notably through telecentric designs. The size of the sensor is significantly smaller than for most DSLRs and this implies that lenses, especially telephoto lenses, can be smaller. For example, a Fou ...

Olympus Pen F
The Olympus Pen F, Pen FT and Pen FV are very similar half-frame 35 mm single-lens reflex (SLR) cameras with interchangeable lenses produced by Olympus of Japan between 1963-1966 (Pen F), 1966-1972 (Pen FT) and 1967-1970 (Pen FV). The original Pen F has a double-stroke film advance and a distinctive logo rendered in a gothic font. The later Pen FT added a single-stroke film advance, and an uncoupled, integrated light meter, which uses a system of exposure numbers rather than f-stops. The exposure numbers were added to the aperture rings of later Pen F lenses; the rings could be pulled out and rotated to show conventional f-stops instead. A side-effect of the FT's light meter was a dimmer viewfinder. The Pen FV was essentially a Pen FT with the light meter deleted and the F's brighter viewfinder reinstated. ''Half frame'' means that the camera uses an 18×24 mm vertical (portrait) format, producing twice the pictures on a roll of 135 film as the regular 36×24 m ...

Olympus Corporation
is a Japanese manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus holds roughly a 70-percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Its global headquarters are located in Shinjuku, Tokyo, Japan. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO and the matter snowballed into a corporate corruption investigation with multiple arrests. It paid $646 million in kickback fines in 2016. Products Cameras and audio In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. The first innovative camera series from Olympus was the Pen, launched in 1959. It used a half-frame format, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus OM System
The Olympus OM System was a line of 35mm single-lens reflex cameras, lenses and accessories sold by Olympus between 1972 and 2002. The system was introduced by Olympus in 1972. The range was designed by Yoshihisa Maitani, chief designer for Olympus, and his staff; ''OM'' stands for ''Olympus Maitani''. The nucleus of the system was a series of compact bodies divided into an advanced series and a later consumer-oriented series. The first model was the all-mechanical M-1 which, after pressure from Leica (which already had an M1 model), was renamed OM-1. At the same time the M system was renamed OM System. The camera included a full-aperture TTL Cadmium-sulphide (CdS) exposure meter, and a bayonet lens mount of relatively large diameter. By the end of the 1970s it was joined by the semi-automatic OM-2 and consumer-oriented OM-10. Olympus continued the naming pattern with the 'professional' OM-3 and OM-4, and the consumer-level OM-20, OM-30 and OM-40. The cameras were accompanied by ...

Double-Gauss Lens
The double Gauss lens is a compound lens used mostly in camera lenses that reduces optical aberrations over a large focal plane. Design The double Gauss lens consists of two back-to-back Gauss lenses (a design with a positive meniscus lens on the object side and a negative meniscus lens on the image side) making two positive meniscus lenses on the outside with two negative meniscus lenses inside them. The symmetry of the system and the splitting of the optical power into many elements reduces the optical aberrations within the system. There are many variations of the design. Sometimes extra lens elements are added. The basic lens type is one of the most developed and used photographic lenses. The design forms the basis for many camera lenses in use today, especially the wide-aperture standard lenses used on 35 mm and other small-format cameras. It can offer good results up to with a wide field of view, and has sometimes been made at 1.0. Extra wide aperture f/1.4 Double Gau ...

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] |
Pen D3 (2356963031)
A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing. Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity which had to be periodically recharged by dipping the tip of the pen into an inkwell. Today, such pens find only a small number of specialized uses, such as in illustration and calligraphy. Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens. Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph. All of these modern pens contain internal ink reservoirs, such that they do not need to be dipped in ink while writing. Types Modern Pens commonly used today can be categorized based on the mechanism of the writing tip and the type of ink: * A ballpoint pen dispens ...

Konica C35 AF
The Konica C35 AF was the first mass-produced autofocus camera. it was first released in November 1977. Features This was an autofocus version of the Konica C35 Automatic camera. It featured a fixed-aperture Hexanon 38 mm f/2.8 autofocus lens with a leaf shutter, a built-in electronic flash, and an automatic exposure system to select the appropriate 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 am .... The film advance was mechanical. The shutter was electronically controlled with three speeds, 1/60, 1/125, and 1/250. The exposure system could handle film speeds from ISO 25 to ISO 400 and the built in flash had a guide number of 14 at ISO 100 covering distances from 1.1m to 5m.
