List Of Minolta V-mount Lenses
The Minolta Vectis S-series comprises two APS system models of film SLR cameras made by Minolta, the flagship model Vectis S-1 and the Vectis S-100. The cameras feature a compact design, owing to the use of mirrors instead of prisms in the viewfinder. Only one early DSLR camera body, the Minolta Dimâge RD 3000, also used the V-lens mount. The Vectis brand was also shared with a number of small APS rangefinder cameras with fixed lenses, including the waterproof Vectis Weathermatic and Vectis GX series. The model numbers of these cameras don't include the S prefix used for the SLR series. Vectis V mount The Vectis V mount lenses used by the above models are not compatible with any other lens mount, including Minolta's 35mm A-mount and SR-mount systems. Aperture and focus are controlled electronically by the camera; the image circle of the lenses only illuminates the APS formats, and the flange focal distance For an interchangeable lens camera, the flange focal distance ...

Advanced Photo System
Advanced Photo System (APS) is a discontinued film format for still photography first produced in 1996. It was marketed by Eastman Kodak under the brand name Advantix, by FujiFilm under the name Nexia, by Agfa under the name Futura and by Konica as Centuria. Design The film is 24 mm wide, and has three image formats: * H for "High Definition" (30.2 × 16.7 mm; aspect ratio 16:9; 4×7" print) (1.25 crop compared to 36x24mm full frame) * C for "Classic" (25.1 × 16.7 mm; aspect ratio 3:2; 4×6" print) (1.44 crop compared to 36x24mm full frame) * P for " Panoramic" (30.2 × 9.5 mm; aspect ratio 3:1; 4×11" print) (1.36 crop compared to 36x24mm full frame) The "C" and "P" formats are formed by cropping the 30.2 × 16.7 mm "High Definition" image. The full image is recorded on the film, and an image recorded in one aspect ratio can be reprinted in another. The "C" format has an equivalent aspect ratio to a 135 film image. Most APS cameras (with ... [...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.

Prism (optics)
An optical prism is a transparent optics, optical element with flat, polished surfaces that are designed to refraction, refract light. At least one surface must be angled — elements with two parallel surfaces are ''not'' prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides. Not all optical prisms are prism (geometry), geometric prisms, and not all geometric prisms would count as an optical prism. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, acrylic glass, acrylic and fluorite#Optics, fluorite. A dispersive prism can be used to break white#White light, white light up into its constituent spectral colors (the colors of the rainbow) as described in the following section. Other types of prisms noted below can be used to reflection (physics), reflect light, or to split light into components with different polarization (w ...

Viewfinder
In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of different types: still and movie, film, analog and digital. A zoom camera usually zooms its finder in sync with its lens, one exception being rangefinder cameras. History Before the development of microelectronics and electronic display devices, only optical viewfinders existed. Direct optical viewfinders Direct viewfinders are essentially miniature Galilean telescopes; the viewer's eye was placed at the back, and the scene viewed through the viewfinder optics. A declining minority of point and shoot cameras use them. Parallax error results from the viewfinder being offset from the lens axis, to point above and usually to one side of the lens. The error varies with distance, being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DSLR Camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s. ...

Rangefinder Camera
A rangefinder camera is a camera fitted with a rangefinder, typically a split-image rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus. Most varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel. Older, non-coupled rangefinder cameras display the focusing distance and require the photographer to transfer the value to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory shoe. Earlier cameras of this type had separate viewfinder and rangefinder windows; later the rangefinder was incorporated into the viewfinder. More modern designs have rangefinders coupled to the focusing mechanism so that the lens is focused correctly when the rangefinder images fuse; compare with the ...

Minolta SR-mount
The Minolta SR-mount was the bayonet mounting system used in all 35 mm SLR cameras made by Minolta with interchangeable manual focusing lenses. Several iterations of the mounting were produced over the decades, and as a result, the mount itself was sometimes referred to by the name of the corresponding lens generation (f.e. "MC", "MD" or "X-600") instead. All lenses for these mounts are interchangeable between older and newer Minolta manual focus 35 mm film SLR bodies. There are exceptions, such as, the lenses before 1961 feature a slightly different aperture leverage, and thus the automatic diaphragm may not work correctly on post-1961 cameras, and later MC/MD tabs may hit a screw of the front cover on earlier cameras. Four design enhancements, all forwardly inclusive and backwardly compatible, are: # SR - 1958-1966: Plain SR-bayonet featuring automatic diaphragm. Lenses are labelled ''Rokkor'' (pre-set) or '' Auto Rokkor'' (automatic diaphragm) # MC - 1966-1977: Meter coupling a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flange Focal Distance
For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus or register, depending on the usage and source) of a lens mount system is the distance from the mounting flange (the interlocking metal rings on the camera and the rear of the lens) to the film or image sensor plane. This value is different for different camera systems. The range of this distance, which will render an image clearly in focus within all focal lengths, is usually measured to a precision of hundredths of millimetres, and is not to be confused with depth of field. Lenses can be adapted from one mount (and respective FFD) to another. FFD determines whether infinity focus can be accomplished with a simple non-optical adapter. Optics to correct for distance introduce more cost and can lower image quality, so non-optical lens adapters are preferred. A simple non-optical ada ...
