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 ...
The 40D has a larger memory buffer so more pictures can be taken in succession without a slow down in frame rate. Frames per second has been increased from 5 to 6.5. The 40D adds a new format, Canon's sRAW, which is a smaller RAW image for smaller prints and reduced file sizes. The 40D's RAW format is 14-bit instead of the 12-bit of the 30D. [2]
Canon EOS (Electro-Optical System) is an autofocus single-lens reflex camera (SLR) and mirrorless camera series produced by Canon Inc. Introduced in 1987 with the Canon EOS 650, all EOS cameras used 35 mm film until October 1996 when the EOS IX was released using the new and short-lived APS film.
[2] [3] It was succeeded by the Canon EOS 500D (Rebel T1i in North America) which was announced on 25 March 2009. [4] Like its predecessors, it takes EF and EF-S lenses as well as a large selection of EOS system accessories. The 450D is the first Canon EOS model to exclusively use SD and SDHC card storage instead of CompactFlash. [5]
The "S" in EF-S has variously been described by Canon as coming from either "Small image circle" [1] (the lens projects a smaller image circle than normal EF lenses to match the sensor), or "Short back focus" [2] (the smaller mirror used in APS-C cameras also allows optical elements to protrude further into the camera body, reducing the minimum ...
The free software Canon Hack Development Kit (CHDK) project, started by Andrey Gratchev, has successfully enhanced many Canon PowerShot cameras without replacing the stock firmware. [ 29 ] [ 30 ] It allows programmatic control of many Canon compact cameras, enabling users to add features, including games and scripts written in UBASIC or Lua .
The 400mm f / 4 DO IS II USM, which replaced an earlier version of the same lens in 2014, [3] is one of only two Canon lenses that make use of diffractive optics (the other is the EF 70–300mm f/4.5–5.6 DO IS USM). The use of diffractive optics allows the lens to be significantly lighter than it might otherwise be.
The Canon EOS 4000D is an 18.0 megapixels digital single-lens reflex camera (DSLR) made by Canon. [1] It was announced on 25 February 2018 with a suggested retail price of €399 including an EF-S 18-55 f/3.5-5.6 III lens. It is also known as the EOS 3000D in some parts of the Asia Pacific region and the EOS Rebel T100 in North America. [2] [3]
