Abbe number. In optics and lens design, the Abbe number, also known as the V-number or constringence of a transparent material, is an approximate measure of the material's dispersion (change of refractive index versus wavelength), with high values of V indicating low dispersion. It is named after Ernst Abbe (1840–1905), the German physicist ...
Exchangeable image file format. A standard format for tag data in digital camera files. [10] f: f-number, f-stop. The numerical value of a lens aperture. The ratio of the focal length of the lens divided by its effective aperture diameter. [4] FF: Full frame, where the image sensor is approximately the same size as a 35 mm film: 36 × 24 mm. FP ...
DCF 1.0 (JEIDA-49-2-1998) Website. ciff-forum .com (Dead link) In digital photography, the Camera Image File Format ( CIFF) file format is a raw image format designed by Canon, and also used as a container format to store metadata in APP0 of JPEG images. [1] Its specification was released on February 12, 1997.
See Canon EF lenses for the product line-up. See Canon EF-S lenses for the product line-up. EF-S lenses are built for APS-C 1.6x crop sensors, so they only work with models that use this sensor size. When EF-S lenses are used on a 35mm (full frame) camera the back element will hit the mirror assembly or cause substantial vignetting since the ...
The L1 was the first camcorder in the world with interchangeable lenses, it uses the Canon VL Lens System. [ 14 ] The Canon L2 , LX-1T (in Japan ), or EX2Hi (in Europe ), is the successor to the L1, but is nearly identical in all but a few features such as the addition of time codes and shuttle-ring-equipped remote control.
Corrective lens. A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye.
Canon EOS 1300D. Canon EOS 1200D is an 18.1 megapixel digital single-lens reflex camera (DSLR) announced by Canon on 11 February 2014. [ 1] It is known as the EOS Kiss X70 in Japan, the EOS Rebel T5 in the Americas, and the EOS Hi in Korea. [ 2][ 3] The 1200D is an entry-level DSLR that introduces an 18 MP sensor from the 700D and 1080p HD ...
Raw image format. A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. [ 1][ 2] Raw files are so named because they are not yet processed, and contain large amounts of potentially redundant data.
