A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system 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.
Minolta Co., Ltd. was a Japanese manufacturer of cameras, camera accessories, photocopiers, fax machines, and laser printers. Minolta Co., Ltd., which is also known simply as Minolta, was founded in Osaka, Japan, in 1928 as Nichi-Doku Shashinki Shōten. It made the first integrated autofocus 35 mm SLR camera system. In 1931, the company adopted its final name, an acronym for "Mechanism, Instruments, Optics, and Lenses by Tashima".
Konica was a Japanese manufacturer of, among other products, film, film cameras, camera accessories, photographic and photo-processing equipment, photocopiers, fax machines and laser printers, founded in 1873. The company merged with Japanese peer Minolta in 2003, with the new company named Konica Minolta.
The Pentax Auto 110 and Pentax Auto 110 Super were fully automatic single-lens reflex cameras manufactured by Asahi Pentax for use with Kodak 110 film cartridges. The Auto 110 was introduced with three interchangeable, fixed focal length lenses in 1978. A further three lenses were added in 1981 to coincide with the release of the Auto 110 Super the following year. The camera system was sold until 1985. The complete system is sometimes known as the Pentax System 10, apparently for its official Pentax name, although most Pentax advertising only uses the camera name or Pentax-110. This model represented the only complete ultraminiature SLR system manufactured for the 110 film format, although several fixed-lens 110 SLRs were sold. The camera system also claims to be the smallest interchangeable-lens SLR system ever created.
A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor.
Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 31.15 mm field diameter. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm and Ø 31.11 mm field diameter.
The Nikon FG is an interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by Nippon Kogaku K. K. in Japan from 1982 to 1986.
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 Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.
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.
Bridge cameras are cameras that fill the niche between relatively simple point-and-shoot cameras and interchangeable-lens cameras such as mirrorless cameras and single-lens reflex cameras (SLRs). They are often comparable in size and weight to the smallest digital SLRs (DSLR), but lack interchangeable lenses, and almost all digital bridge cameras lack an optical viewfinder system. The phrase "bridge camera" has been in use at least since the 1980s, and continues to be used with digital cameras. The term was originally used to refer to film cameras which "bridged the gap" between point-and-shoot cameras and SLRs.
Sony α is a digital camera system introduced on 5 June 2006. It uses and expands upon Konica Minolta camera technologies, including the Minolta AF SLR lens mount, whose assets were acquired by Sony after the end of Konica Minolta's photography operations in early 2006. Sony also has an 11.08% ownership stake in Japanese lens manufacturer Tamron, which is known to have partnered with Konica Minolta and Sony in the design and manufacture of many zoom lenses.
The Leica R bayonet mount is a camera lens mount system introduced by Leitz in 1964. The R mount is the standard method of connecting a lens to the Leica R series of 35 mm single-lens reflex cameras. The mount is descended from those used for the Leicaflex, Leicaflex SL and Leicaflex SL2 SLR cameras, but differs in the cams used to communicate lens aperture information to the camera. 3 cam lenses are compatible with all of the Leica SLR cameras, while R-only lenses have a slightly different mount shape that will not fit on the earlier cameras.
The Minolta A-mount camera system was a line of photographic equipment from Minolta introduced in 1985 with the world's first integrated autofocus system in the camera body with interchangeable lenses. The system used a lens mount called A-mount, with a flange focal distance 44.50 mm, one millimeter longer, 43.5 mm, than the previous SR mount from 1958. The new mount was wider, 49.7 mm vs. 44.97 mm, than the older SR-mount and had a longer flange focal distance making old manual lenses incompatible with the new system. Minolta bought the autofocus technology of Leica Correfot camera which was partly used on the a-mount autofocus technology. The mount is now used by Sony, who bought the SLR camera division from Konica Minolta, Konica and Minolta having merged a few years before.
Originally produced by Minolta, and until recently, produced by Sony, the AF Reflex 500mm f/8 is a catadioptric photographic lens compatible with cameras using the Minolta A-mount and Sony A-mount lens mounts.
The Konica Hexar RF is a 35 mm rangefinder camera which was sold by Konica. It was introduced to the market on 13 October 1999. and subsequently discontinued some time before the end of 2003. The camera used the "Bayonet Konica KM-mount", a copy of the Leica M-mount, thus sharing interchangeable lenses with those designed for Leica cameras and others compatible with them. The Hexar RF has a combined rangefinder/viewfinder modeled on that of Leica cameras, a similar body shape and size - and so is similar to Leica M-mount cameras in many aspects of operation.
This article is about photographic lenses for single-lens reflex film cameras (SLRs) and digital single-lens reflex cameras (DSLRs). Emphasis is on modern lenses for 35 mm film SLRs and for DSLRs with sensor sizes less than or equal to 35 mm ("full-frame").
The E-mount is a lens mount designed by Sony for their NEX and ILCE series of camcorders and mirrorless cameras. The E-mount supplements Sony's α mount, allowing the company to develop more compact imaging devices while maintaining compatibility with 35mm sensors. E-mount achieves this by:
The Sony α NEX-5 is a digital camera launched on 11 May 2010. It is a mirrorless interchangeable lens camera with the body size of a larger model fairly compact point-and-shoot camera with a larger sensor size (APS-C) comparable to that of some digital single-lens reflex cameras. Its major competitors in the market are the cameras based on the micro 4/3 standard created by Panasonic and Olympus, and a few low end Canon, Nikon, and even Sony α DSLRs. The NEX-5 shoots 14.2 megapixel stills and has a 7 frame/s continuous shotmode. It has the capability to shoot 1920×1080i at 60 frame/s in AVCHD or 1440×1080p at 30 frame/s in MPEG4. The NEX-5 was replaced by the 16 megapixel NEX-5N in August 2011.
The Panasonic Lumix DMC-G2 is a digital mirrorless interchangeable lens camera adhering to the Olympus and Panasonic developed Micro Four Thirds System (MFT) system design standard. It was announced in March 2010 along with a lesser featured Panasonic Lumix DMC-G10.
