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]
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 ...
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]
When used on a camera with a field of view compensation factor of 1.6x, such as the Canon EOS 400D, they provide a narrower field of view, equivalent to an 800 mm lens mounted on a 35mm frame body. With a 1.3x body such as the Canon EOS-1D Mark III, they provide a less narrow field of view, equivalent to a 650mm lens mounted on a 35mm frame body.
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 350D is the successor to the Canon EOS 300D, which was the first sub-US$1000 digital SLR, introduced in 2003. [1] There are some differences between the 350D and the 300D. [2] Many of the features 'locked out' by Canon in the 300D were unlocked in this camera, so it has been subject to less unofficial 'hacking' to release the locked features.
