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 ...
The shallow depth of field provided by a telephoto lens also allows the subject of the photography to stand out better against the background. [11] Infrared corrected special-low-dispersion glass also has benefits to CCTV cameras. The low chromatic aberration of SLD glass allows the lens to always stay in focus, from visible light to infrared. [12]
An optical instrument is said to be diffraction-limited if it has reached this limit of resolution performance. Other factors may affect an optical system's performance, such as lens imperfections or aberrations, but these are caused by errors in the manufacture or calculation of a lens, whereas the diffraction limit is the maximum resolution ...
Diagonal. 75°–27°. Retail info. MSRP. $189.99 USD. The Canon EF 28–90mm f/4–5.6 is a full frame SLR zoom lens, also often included as a kit lens with Canon EOS film cameras. The maximum aperture is f/ 4 at 28mm, reducing to f/ 5.6 at 90mm. When set to 90mm, this will create a moderate amount of background blur for portrait photography.
In optics, the Abbe sine condition is a condition that must be fulfilled by a lens or other optical system in order for it to produce sharp images of off-axis as well as on-axis objects. It was formulated by Ernst Abbe in the context of microscopes. [ 1] The Abbe sine condition says that. the sine of the object-space angle should be ...
It is the successor of the Canon EOS 350D, and upgrades to a 10.1 megapixel CMOS sensor, a larger continuous shooting buffer, an integrated image sensor vibrating cleaning system (first used in a Canon EOS DSLR), a more precise nine-point autofocus system from the EOS 30D, improved grip, and a bigger 2.5-inch (64 mm) LCD with 230,000 pixels and a larger viewing angle which replaces the top ...
Canon EOS 350D. The Canon EOS 300D, manufactured by Canon, was marketed in North America as the EOS Digital Rebel, in Japan as the EOS Kiss Digital, and was also sold as the DS6041. It is a 6.3- megapixel entry-level digital single-lens reflex camera. It was initially announced on 20 August 2003 at a price point of $899 without lens, $999 with ...
Canon EOS C300, first model of the lineup Canon EOS 1D C Canon EOS C100 Canon EOS C500 Canon EOS C70. The Canon Cinema EOS (Cinema Electro-Optical System) autofocus digital photographic and cinematographic SLR and mirrorless interchangeable lens camera system was introduced in late 2011 with the Canon EOS C300 and followed by the Canon EOS C500 and Canon EOS 1D C in early 2012.
