Information: - Nikonos Calypso is the name of a series of 35mm format cameras specifically designed for underwater photography launched by Nikon in 1963. The early Nikonos cameras were improvements of the Calypso camera, which was an original design by Jacques-Yves Cousteau and Belgian engineer Jean de Wouters - The Nikon F camera, introduced in April 1959, was Nikon's first SLR camera. It was one of the most advanced cameras of its day. Although many of the concepts had already been introduced elsewhere, it was revolutionary in that it was the first to combine them all in one camera. It was produced until October 1973 and was replaced by the quite similar Nikon F2. Aspects of its design remain in all of Nikon's subsequent SLR cameras, through the current Nikon F6 film and Nikon D5 digital models (which still share its Nikon F-mount for lenses). The "F" in Nikon F was selected by Nippon Kogaku from the letter F of the name of the designer of the bayonet mount, Mr. Fuketa. That tradition was carried all the way through their top line of Nikon cameras until the introduction of the Nikon D1 (digital) cameras decades later. - Large format refers to any imaging format of 45inches (102127mm) or larger. Large format is larger than "medium format", the 66cm (22 inch) or 69cm (23 inch) size of Hasselblad, Rollei, Kowa, and Pentax cameras (using 120- and 220-rollfilm), and much larger than the 2436mm (~ 1.0x1.5inch) frame of 35mm format. The main advantage of large format, film or digital, is higher resolution at the same pixel pitch, or same resolution with more larger pixels or grain. A 45inch image has about 16times the area, and thus 16 the total resolution, of a 35mm frame. - Its products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer. The companies held by Nikon form the Nikon Group. Among its products are Nikkor imaging lenses (for F-mount cameras, large format photography, photographic enlargers, and other applications), the Nikon F-series of 35 mm film SLR cameras, the Nikon D-series of digital SLR cameras, the Coolpix series of compact digital cameras, and the Nikonos series of underwater film cameras. Nikon's main competitors in camera and lens manufacturing include Canon, Sony, Fujifilm, Panasonic, Pentax, and Olympus. - The 70 - 210mm lens is a telephoto zoom lens made by Nikon . The lens has an F - mount to work with all compatible Nikon SLRs and DSLRs . As opposed to the various f / 2.8 versions of the 70 - 210 Focal length , the f / 4 and slower versions of such lenses are marketed to amateurs , accounting for their price . However , the Nikkor AF 70 - 210 f / 4 variant is a two - touch system ( dedicated focus and zoom rings ) , compared to the rest of the lens range , which utilizes a one - touch ( push - pull ) system for focusing and zooming . The lens comes in five different versions . f / 4.5 - 5.6 f / 4 Series E f / 4 AF f / 4 - 5.6 AF f / 4 - 5.6 AF - D - Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount. - Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of a measurement is dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the "International vocabulary of metrology" published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales. - Photolithography, also termed optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate. A series of chemical treatments then either engraves the exposure pattern into, or enables deposition of a new material in the desired pattern upon, the material underneath the photo resist. For example, in complex integrated circuits, a modern CMOS wafer will go through the photolithographic cycle up to 50 times. - , better known as Fujifilm or simply Fuji, stylized as FUJiFILM, is a Japanese multinational photography and imaging company headquartered in Tokyo. - 35mm film (millimeter) is the film gauge most commonly used for motion pictures and chemical still photography (see 135 film). The name of the gauge refers to the width of the photographic film, which consists of strips 34.980.03mm (1.3770.001inches) wide. The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. For still photography, the standard frame has eight perforations on each side. - Pentax () is a brand name used primarily by Ricoh Imaging Company for cameras, sport optics (including binoculars and rifle scopes), and CCTV optics. The brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses. - Sony Corporation is the electronics business unit and the parent company of the Sony Group, which is engaged in business through its four operating components electronics (video games, network services and medical business), motion pictures, music and financial services. These make Sony one of the most comprehensive entertainment companies in the world. Sony's principal business operations include Sony Corporation, Sony Pictures Entertainment, Sony Interactive Entertainment, Sony Music Entertainment, Sony Mobile (formerly Sony Ericsson) and Sony Financial. Sony is among the Semiconductor sales leaders by year and as of 2013, the fourth-largest television manufacturer in the world, after Samsung Electronics, LG Electronics and TCL. - A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. - A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Steppers are an essential part of the complex process, called photolithography, that creates millions of microscopic circuit elements on the surface of tiny chips of silicon. These chips form the heart of ICs such as computer processors, memory chips, and many other devices. - A microscope (from the , "mikros", "small" and , "skopein", "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. - , formerly known as , is a Japanese multinational electronics corporation headquartered in Kadoma, Osaka, Japan. - Binoculars or field glasses are binocular telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal mounted military models.
