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 ...
Magic Lantern is a firmware add-on for various Canon digital single-lens reflex (DSLR) cameras and the EOS M. [2] It adds features for DSLR filmmaking and still photography, and is free and open-source. Magic Lantern was originally written for the Canon EOS 5D Mark II [3] by Trammell Hudson in 2009 after he reverse engineered its firmware. [1]
The internal auto-diaphragm Miranda cameras consisted of the Miranda 'D', the popular Miranda 'F', the 'FV' and the 'G' model, which had a larger than normal reflex mirror thereby eliminating viewfinder image vignetting when the camera was used with long telephoto lenses. Miranda cameras were known in some photographic discussions as 'the poor ...
The Nikon F-mount lens systems and the Pentax K-mount systems are the only 35 mm SLR camera systems (apart from the Leica M-mount rangefinder system) that allow a photographer to use a mechanical SLR camera body, a fully automatic SLR camera body, and a DSLR camera body, all utilizing the same lenses.
All current film and digital SLR cameras produced by Canon today use the EOS autofocus system. Canon introduced this system in 1987 along with the EF lens mount standard. The last non-EOS based SLR camera produced by Canon, the Canon T90 of 1986, is widely regarded as the template for the EOS line of camera bodies, although the T90 employed the ...
However, small digital cameras can focus better on closer objects than typical DSLR lenses. The sensors used in current DSLRs — "full-frame" which is the same size as 35mm film, APS-C, and Four Thirds System — are much larger than most digital cameras. Entry-level compact cameras typically use sensors known as 1/2.3″, which is 3% the size ...
