Canon EF 70–300mm lens

Last updated

The EF 70–300mm lenses are a series of telephoto zoom lenses made by Canon Inc. They have a Canon EF lens mount to work with the EOS line of cameras.

Telephoto lens

In photography and cinematography, a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group.

Zoom lens lens with a variable focal length

A zoom lens is a mechanical assembly of lens elements for which the focal length can be varied, as opposed to a fixed focal length (FFL) lens.

Canon Inc. is a Japanese multinational corporation specializing in the manufacture of imaging and optical products, including cameras, camcorders, photocopiers, steppers, computer printers and medical equipment. It's headquartered in Ōta, Tokyo, Japan.

Four Canon EF telephoto zoom lenses carry the 70–300mm designation.

All versions offer image stabilization (IS) and ultrasonic motor drive (USM) and have nearly the same maximum aperture of 4/4.5 to 5.6 over their entire focal range.

Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.

An ultrasonic motor is a type of electric motor powered by the ultrasonic vibration of a component, the stator, placed against another component, the rotor or slider depending on the scheme of operation. Ultrasonic motors differ from piezoelectric actuators in several ways, though both typically use some form of piezoelectric material, most often lead zirconate titanate and occasionally lithium niobate or other single-crystal materials. The most obvious difference is the use of resonance to amplify the vibration of the stator in contact with the rotor in ultrasonic motors. Ultrasonic motors also offer arbitrarily large rotation or sliding distances, while piezoelectric actuators are limited by the static strain that may be induced in the piezoelectric element.

Aperture Hole or an opening through which light travels

In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane.

The EF 70–300mm f/4.5–5.6 DO IS USM lens

This lens makes use of Canon's Diffractive Optics rather than a traditional lens of wholly refractive design. This allows the lens to be more compact, albeit heavier and much more expensive than a lens of conventional design. The lens contains Image Stabilization and a ring USM, which allows full-time manual focusing of the lens while using the camera in single shot mode. This lens offers good optical quality with the caveat that the diffractive element does not deal with strong incident light sources as well as conventional designs. [1]

This lens is compatible with the Canon ET-65B lens hood. [2]

Lens hood photographic equipment

In photography, a lens hood or lens shade is a device used on the front end of a lens to block the Sun or other light source(s) to prevent glare and lens flare. Lens hoods may also be used to protect the lens from scratches and the elements without having to put on a lens cover.
The geometry of a lens hood is dependent on three things: the focal length of the lens, the size of the front lens element and the dimensions of the image sensor or film in the camera.

This lens is of a conventional design and was introduced in 2005, to offer an increase in performance from the earlier 75-300mm lenses in the Canon EF lens lineup. [3] [4] Like the 70–300mm f/4.5–5.6 DO it contains an image stabilizer; however, for focusing it uses the lower quality micro-USM design, and therefore requires the focus motor to be disengaged before manual focusing. The optical performance of this lens is competitive to Canon's L series telephoto zoom lenses, such as the 70–200mm series of lenses. This is because it features an ultra-low dispersion glass element, something that is uncommon for a consumer grade lens, and is usually found only in Canon's L-series lenses. This lens is also notable for having only a slight decrease in performance as the focal length goes beyond 200 mm. [5] That is an uncommon attribute of consumer grade zoom lenses and is not the case for the old 75–300mm lens.

Canon L lens

Canon's series of L lenses are a professional line of photography lenses made by Canon. Canon has sold zoom and prime L-series lenses for the discontinued FD lens mount, for the current EF lens mount used on all Canon EOS SLR cameras and for the RF mount used on full-frame mirrorless interchangeable-lens cameras.

Canon EF 70–200mm lens camera lens

The EF 70–200mm lenses are a group of telephoto zoom full-frame lens made by Canon Inc. The lenses have an EF mount to work with the EOS line of cameras.

Dispersion (optics)

In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency.

This lens is compatible with the Canon ET-65B lens hood. [2]

The EF 70–300mm f/4–5.6 L IS USM lens

Introduced on 26 August 2010, this lens is in Canon's L-series range of professional lenses. The lens includes 19 elements in 14 groups, two of which are ultra-low dispersion (UD) glass. It is designed to provide professional photographers the 70–300mm zoom range without sacrificing high image quality. The 70–300mm f/4–5.6L IS USM is the only L-series 70–300mm lens and is the only to feature weather sealing. The image stabilizer is rated for 4 stops and allows sharp pictures to be taken handheld at speeds as slow as 1/8 of a second. This lens has superb contrast that meets or exceeds other L-series telephoto zooms, but lacks in sharpness in the corners throughout most of its focal length range. The image quality at 300mm does not degrade, making it distinct from the other 70–300mm lenses. Barrel distortion is average for this class of lens, but vignetting is better than average. Because of its fast autofocus, useful range, excellent image stabilization, and high image quality, the 70–300mm f/4–5.6L has recently become popular among serious amateur and professional photographers. The 70–300mm f/4–5.6L includes a hood but not a tripod ring.

EF 70–300mm f/4–5.6 IS II USM

Introduced on 15 September 2016, Canon EF 70-300mm f/4-5.6 IS II USM lens is the second Canon lens equipped with Nano USM technology, a focusing motor that combines the benefits of a ring USM (ultrasonic motor) for high-speed AF during still photo shooting and lead-screw type STM (stepping motor) for smooth and quiet video autofocusing (AF). [6] The lens also features a new LCD information display and four-stop image stabilization. It was available in November 2016, for an estimated retail price of $549.99. [7] To support this new lens, some of Canon cameras needed a new firmware. [8]

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.

Canon EF 24–70mm lens camera lens

The Canon EF 24–70mm lens is a family of professional EF mount wide-to-normal zoom lenses manufactured and sold by Canon. The first of the family, the EF 24–70mm f/2.8L, was introduced in 2002 to replace the well-regarded 28–70mm f/2.8L. Two later versions were announced in 2012. The first of these, the EF 24–70mm f/2.8L II, was announced by Canon in February, but would not ship to customers until September of that year. This lens replaced the Mk I, and had an MSRP of US$2299 when introduced. The latest member of the family is the EF 24–70mm f/4L IS USM, which became available in January 2014. The f/4 version, which is the first of the family to include image stabilization, was initially reported to be the standard kit lens for the Canon EOS 6D, but did not appear in 6D kits in most markets until late 2014, and 5D Mark IV kit in 2016.

Canon EF 16–35mm lens

The EF 16–35 mm lens is a family of professional wide-angle lenses made by Canon Inc. The original version, the EF 16-35mm f/2.8L USM, replaced the EF 17-35mm f/2.8L USM lens, which had itself replaced the EF 20-35mm f/2.8L lens.

Canon EF 17–40mm lens

The EF 17–40mm f/4L USM lens is a wide-angle lens made by Canon Inc. The lens has an EF mount to work with the EOS line of cameras. Other than the front element, it is sealed against dust and water, and features a diaphragm which remains nearly circular from f/4 to f/8. It is one of the few Canon photo lenses that are parfocal.

Canon EF 50mm lens Wikimedia disambiguation page

The EF 50mm lenses are a group of normal prime lenses made by Canon that share the same focal length. These lenses are based on the classic double-Gauss lens, with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3 and its faster cousins adding additional elements. The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.

The Canon EF 28–105 mm f/4–5.6 is an inexpensive zoom lens often included as a kit lens with Canon 35 mm single-lens reflex cameras. 28–105 mm is a standard wide to telephoto zoom range. The Canon EF 28–105 mm f/3.5–4.5 USM is a higher quality zoom lens with a better build quality. Currently every version of this lens is discontinued. Some versions of the lens may include the word macro or a flower icon which indicates macro capability, however due to the 1:5.2 image magnification ratio it cannot be considered as a true macro lens.

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-S 10–22mm lens camera lens

The Canon EF-S 10–22mm f/3.5–4.5 USM lens is a wide to ultra-wide angle zoom lens for Canon digital single-lens reflex cameras with a Canon EF-S lens mount. The field of view has a 35 mm equivalent focal length of 16–35mm, which is analogous to the EF 16–35mm f/2.8L on a full-frame camera. The 10–22mm is an internal focusing lens. Of the 13 elements, one is of Canon's Super Ultra-Low Dispersion glass and three are aspherical elements.
