Nikon DX/Sigma DC/Tamron Di II/Tokina DX: Denotes a lens that is designed for APS-C DSLR sensors. Use of this lens on a full-frame (FX) sensor will likely cause vignetting. All full-frame Nikon DSLRs are able to detect DX lenses and crop the image accordingly by default. However, the viewfinder view is likely to be constricted.
An APS-C format SLR (left) and a full-frame DSLR (right) show the difference in the sizes of the image sensors. The angle of view of a lens depends upon its focal length and the camera's image sensor size; a sensor smaller than 35 mm film format (36×24 mm frame) gives a narrower angle of view for a lens of a given focal length than a camera ...
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.
The first commercially produced SLR that employed a roof pentaprism was the Italian Rectaflex A.1000, shown in full working condition on Milan fair April 1948 and produced from September the same year, thus being on the market one year before the east German Zeiss Ikon VEB Contax S, announced on May 20, 1949, produced from September.
[103] [272] [273] Had internal cadmium sulfide (CdS) photoresistive cells mounted behind non-silvered slits in the reflex mirror for coupled center-the-needle, open aperture, full area averaging metering with auto-diaphragm lenses. [274] [275] Film is rated at a particular "speed" sensitivity. It needs a specific amount of light to form an image.
The centre of the diaphragm's aperture coincides with the optical axis of the lens system. Most modern cameras use a type of adjustable diaphragm known as an iris diaphragm, and often referred to simply as an iris. See the articles on aperture and f-number for the photographic effect and system of quantification of varying the opening in the ...
The Nikon D700 is a professional-grade full-frame digital single-lens reflex camera introduced by the Nikon Corporation in July 2008 and manufactured in Japan. [2] It uses the same 12.1-megapixel "FX" CMOS image sensor as the Nikon D3, and is Nikon's second full-frame digital SLR camera.
