Micro-Nikkor
Micro-Nikkor is a family of macro lenses produced by Nikon for their 35mm film and digital cameras. The first Micro-Nikkor lens was the 5cm lens introduced in 1956 for Nikon's S-mount rangefinder cameras. It was designed to produce microforms of texts written in Japanese using the Kanji alphabet, a task that, according to Nikon's corporate history, western microphotography systems were ill-equipped to handle, as Kanji text contains many more small details compared to Latin texts. The 5cm was later modified to have a slightly higher focal length of 55mm to accommodate the longer flange-focal distance of Nikon's SLR Nikon F-mount, F-mount. Longer focal-length Micro-Nikkors were released later, with the 105mm first appearing in 1970 and the 200mm being released in 1978. The Micro-Nikkor family of lenses went through a large number of revisions over the decades, the most recent models are designed for the Nikon Z-mount. A common feature of Micro-Nikkor lenses is that they reach at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon F-mount
The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras. The F-mount was first introduced on the Nikon F camera in 1959, and features a three-lug bayonet mount with a 44mm throat and a Flange focal distance, flange to focal plane distance of 46.5mm. The company continues, with the 2020 D6 model, to use variations of the same lens mount specification for its film and digital single-lens reflex camera, digital SLR cameras. The Nikon F-mount successor is the Nikon Z-mount. History The Nikon F-mount is one of only two SLR lens mounts (the other being the Pentax K-mount) which were not abandoned by their associated manufacturer upon the introduction of autofocus, but rather extended to meet new requirements related to light meter, metering, autofocus, and aperture control. The large variety of F-mount compatible lenses makes it the largest system of interchangeable flange-mount photographic lenses in history. Over ...

Nikonos
Nikonos is the brand 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), Calypso camera, which was an original design by Jacques-Yves Cousteau and Belgian engineer Jean de Wouters. It was produced in France by La Spirotechnique (currently Aqua Lung America, Aqua Lung) until the design was acquired by Nikon to become the Nikonos. The Nikonos system was immensely popular with both amateur and professional underwater photographers. Its compact design, ease of use, and excellent optical quality set the standard for several decades of underwater imaging. Nikon ceased development and manufacture of new Nikonos cameras in 2001, but the camera remains popular, and there is a large and active secondary market. History Nippon Kogaku trace their underwater camera history back to 1956, when the company developed an underwater housing for the Nikon S2 rangefinder ...

Nikon S-mount
The Nikon S-mount is a type of interchangeable lens mount used by a series of Nikon 35 mm rangefinder cameras ( Nikon I, Nikon M, Nikon S, Nikon S2, Nikon SP, Nikon S3, Nikon S4). The lenses were sold under the name Nikkor. Technical details The mount was a mechanical copy of the Zeiss Ikon Contax rangefinder mount, however, small differences between the two mean that although Zeiss wide-angle lenses can be used on the Nikon cameras and vice versa, the longer lenses (50 mm and above), if used, will not be able to focus at both close range and infinity. Nikon made a small number of longer focal length lenses specifically designed to focus properly when mounted on a Contax. These were the 85 mm, 105 mm, and 135 mm lenses. Each was marked with a "C" on the side of the lens barrel. This is not to be confused with a "C" mark used as a suffix to the serial number. Some early Nikkors used this mark to denote that the lenses were coated. The mount itsel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2023 Obiektyw AF-S DX Micro NIKKOR 85mm F 3
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Macro Photography
Macro photography (or photomacrography or macrography, and sometimes macrophotography) is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life-size (though ''macrophotography'' also refers to the art of making very large photographs). By the original definition, a macro photograph is one in which the size of the subject on the negative or image sensor is life-size or greater. In some senses, however, it refers to a finished photograph of a subject that is greater than life-size. The ratio of the subject size on the film plane (or sensor plane) to the actual subject size is known as the reproduction ratio. Likewise, a macro lens is classically a lens capable of reproduction ratios of at least 1:1, although it often refers to any lens with a large reproduction ratio, despite rarely exceeding 1:1. Apart from technical photography and film-based processes, where th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Focusing
An internal focusing lens (abbreviated as IF) is a photographic lens design in which focus is adjusted by moving internal lens element(s). In contrast, traditional ''unit focusing'' lenses are focused by adjusting the distance between the entire set of lens elements and the imaging plane, usually through a helicoid or rack and pinion mechanism. Characteristics Unit focusing prime lenses do not rotate or shift the front lens element; the entire lens moves in a linear direction perpendicular to the imaging plane. As an alternative, some prime and zoom lenses use ''front cell focusing'', in which only the front element(s) of the lens are moved to adjust focus; however, with front cell focusing, typically the front element(s) rotate as focus is adjusted. Starting in the 1960s, optical designers began developing ''floating element'' lenses, which incorporate elements from zoom lens design and automatically adjust the internal distance between element(s) and group(s) as the lens is foc ...

Ring Flash
A ring flash is a circular light that is often operated with a camera lens in the center to take photographs. Unlike point light sources, a ring flash can illuminate a subject with minimal shadows by closely and evenly surrounding the optical axis of the camera lens. This makes it a popular choice for various types of photography, including macro, portrait and fashion photography. Closely related to the ring flash is the continuous ring light, which can produce a consistent level of light for video recording or to see a live preview before capturing photographs. Continuous ring lights are popular for improving picture quality on video calls, social media selfies, and video blogging. For example, Cornell University offers a photo kiosk equipped with a continuous ring light and iPad to take social media profile pictures for students, faculty, staff, and alumni. Modern continuous ring lights frequently use light-emitting diodes (LEDs) because they are bright, energy-efficient, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
