History
Introduction September 1996

The EF 24–85mm f/3.5–4.5 is an EF mount wide-to-normal zoom lens. It was introduced by Canon in 1996. The lens was originally sold with the Canon EOS IX, an APS film SLR, [1] although it was fully compatible with Canon's 35mm film SLRs. The lens was available in two colour schemes; silver when sold with the EOS IX, and black when sold separately. [2] The lens remained in production during Canon's shift to digital SLRs and was often included in press images of the Canon EOS D30. [3] [4] As of June 2010 it is no longer listed on Canon's North American product page. [5]

Canon EF lens mount standard lens mount on the Canon EOS family

Introduced in 1987, the EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers.

Wide-angle lens

In photography and cinematography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it.

In photography and cinematography, depth compression and expansion with shorter or longer focal lengths introduces noticeable, and sometimes disturbing, distortion while a normal lens is a lens that reproduces a field of view that appears "natural" to a human observer.

Canon EOS 300D digital camera model

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 the "kit" lens. It is part of the Canon EOS line of cameras. This was a significant milestone in digital cameras, as it was the first digital SLR offered under $1000.

Canon EOS 10D still camera

The Canon EOS 10D is a discontinued 6.3-megapixel semi-professional digital SLR camera, initially announced on 27 February 2003. It replaced the EOS D60, which is also a 6.3-megapixel digital SLR camera. It was succeeded by the EOS 20D in August 2004.

Canon EOS digital camera product line from Canon

Canon EOS 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. In 2000, the D30 was announced, as the first digital SLR designed and produced entirely by Canon. Since 2005, all newly announced EOS cameras have used digital image sensors rather than film. The EOS line is still in production as Canon's current digital SLR (DSLR) range, and, with the 2012 introduction of the Canon EOS M, Canon's mirrorless interchangeable-lens camera (MILC) system.

APS-C image sensor format

Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2.

A kit lens is a "starter" lens which can be sold with an interchangeable-lens camera such as a single-lens reflex camera. It is generally an inexpensive lens priced at the lowest end of the manufacturer's range so as to not add much to a camera kit's price. The kit consists of the camera body, the lens, and various accessories usually necessary to get started in SLR photography. A kit lens can be sold by itself outside of a kit, particularly the ones that are moderately expensive; for instance a kit lens included in a prosumer SLR kit is often marketed as an upgrade lens for a consumer SLR. In addition, retailers often have promotions of standalone low-end SLR bodies without the lens, or a package that bundles the SLR body with one or two more expensive lenses.

Canon EOS 5D digital camera model

The EOS 5D is a 12.8 megapixel digital single-lens reflex (DSLR) camera body produced by Canon. The EOS 5D was announced by Canon on 22 August 2005, and at the time was priced above the EOS 20D but below the EOS-1D Mark II and EOS-1Ds Mark II in Canon's EOS digital SLR series. The camera accepts EF lens mount lenses.

Full-frame digital SLR

A full-frame digital single-lens reflex camera (DSLR) is one with an image sensor format that is the same size as 35 mm format film. Historically, 35 mm was considered a small film format compared with medium format, large format and even larger.

Canon EOS D30 digital camera model

The Canon EOS D30 is a discontinued 3.1-megapixel professional digital single lens reflex camera (DSLR) body, initially announced by Canon on May 17, 2000. It is part of the Canon EOS line of cameras and uses the EF lens mount. The EOS D30 was Canon's first "home grown" digital SLR. Before that point Canon had a contract with Kodak to rebrand the Kodak 2-megapixel DCS 520 as Canon EOS D2000 and the 6-megapixel DCS 560 as Canon EOS D6000 digital SLRs, which combined Kodak digital backs and Canon camera bodies.

Canon EF-S 17–85mm lens

The Canon EF-S 17–85mm f/4–5.6 IS USM is a standard zoom lens for Canon digital single-lens reflex cameras with an EF-S lens mount and image stabilization. The EF-S designation means it can only be used on EOS cameras with an APS-C sensor released after 2003. The field of view has a 35 mm equivalent focal length of 27.2–136mm, and it is roughly equivalent to the Canon EF 28-135mm lens on a 35mm film SLR. Despite the word "macro" being present on the lens body, this lens is not capable of true 1:1 macro photography.

Canon EF-M camera

The Canon EF-M was an manual-focus 35mm film, SLR camera which used the Canon EF lens mount. It was introduced in 1991 for export to the non-Japanese market, and was the only manual focus camera in the EF line. It was not sold as part of the EOS range; the camera's official name was Canon EF-M rather than Canon EOS EF-M.
