MELVILLE, NY, February 3, 2021 - Canon U.S.A., Inc., a leader in digital imaging solutions, announced today that its parent company, Canon Inc., reached a new lens-manufacturing milestone with the production in January 2021, of the Company’s 150-millionth RF and EF series interchangeable lens for EOS cameras — an RF 70-200mm F2.8 L IS USM telephoto zoom lens (released in November 2019).
Production of interchangeable EF lenses for Canon EOS-series AF (Autofocus) single-lens reflex film cameras began in 1987 at the Company’s Utsunomiya Plant. Over the years, EF lenses have gained support from a wide range of users and production has since expanded to a total of four manufacturing bases, including Canon Inc., Taiwan; Canon Opto (Malaysia) Sdn. Bhd.; and Oita Canon Inc. in southern Japan.
EF lens production passed the 10-million-unit mark in 1995 and crossed the 50-million-unit threshold in 2009. In April 2014, the Company celebrated its first-in-the-world achievement of having manufactured 100 million interchangeable lenses, and now, setting a new world record for the most interchangeable lenses produced, Canon manufactured its 150-millionth RF and EF lens in January 2021. Laid end-to-end, all of the RF and EF lenses Canon has manufactured thus far would measure approximately 7,736 miles in length — nearly equivalent to the Earth’s diameter, which measures approximately 7,917 miles.
Canon’s proprietary EF lenses, launched in March 1987 along with the EOS SLR camera system, have continued to evolve since their introduction, leading the industry through the incorporation of a wide range of innovative technologies, including such world’s firsts as the Ultrasonic Motor (USM), Image Stabilizer (IS) technology, and a multilayered diffractive optical (DO) element.
In 2018, Canon introduced the EOS R system and the RF series lenses, which pursues new heights of quality under the core concept of “Speed, Comfort and High Image Quality.” Today, the Company’s extensive RF and EF lens series lineup currently comprises a total of 118 models, expanding the possibilities for image capture. In addition, thanks to the extensive lineup of lenses, Canon has maintained the number one market share for digital interchangeable-lens cameras since 2003 — a total of 17 years— and in September 2019, the Company celebrated the production of 100 million EOS-series interchangeable-lens cameras.
Canon will continue refining its imaging technologies centered on its RF and EF lens lineup, striving to cater to the varying needs of photographers — from first-time users to advanced amateurs and professionals — while contributing to expanding the photographic and video imaging culture.
Main features, Model name, Release date, and Technologies :
World’s first use of a lens-based Ultrasonic Motor (USM)
EF 300mm f/2.8L USM
Nov. 1987
USM technology delivers fast autofocusing thanks to its high torque and responsiveness. By converting ultrasonic vibrations into rotational energy, the technology makes possible quiet, smooth AF drive performance.
World’s first use of Image Stabilizer (IS) technology
EF 75-300mm f/4-5.6 IS USM
Sept. 1995
Users can see the results of IS technology through the viewfinder. Delivering high precision and stability for superb image stabilization results, this technology expands the possibilities for handheld photography.
World’s first use of a diffractive optical (DO) lens element
EF 400mm f/4 DO IS USM
Dec. 2001
Diffraction is an optical phenomenon in which light waves bend as they pass around the edges of an object. DO lens elements use this phenomenon to correct for a variety of aberrations by controlling the path that light travels.
World’s first use of Subwavelength Structure Coating (SWC)
EF 24mm f/1.4L II USM
Dec. 2008
SWC technology helps to minimize reflections by aligning countless wedge-shaped structures more minute than the wavelength of visible light on the surface of a camera lens.
World’s first use of Hybrid IS, which compensates for both angle camera shake and shift camera shake
EF 100mm f/2.8L Macro IS USM
Oct. 2009
Employing an algorithm, Hybrid IS optimally adjusts for camera shake based on information gathered by two sensors located in the lens. By precisely driving the optical correction system, the technology simultaneously corrects for angle and shift camera shake.
World’s first fisheye lens to deliver both 180-degree diagonal angle of view and 180-degree circular fisheye
EF 8-15mm f/4L Fisheye USM
July 2011
The EF 8-15mm f/4L Fisheye USM enables the capture of images with dramatic deformations, exaggerated perspectives and extreme depths of field, making possible images that are significantly distorted, similar to what a fish might see were it to look skyward from under the water surface.
World’s first super-telephoto zoom lens to employ an internal extender
EF 200-400mm f/4L IS USM Extender 1.4x
May 2013
Featuring a built-in 1.4x extender, the EF 200-400mm f/4L IS USM Extender 1.4x’s zoom range can be expanded with a simple one-touch operation even in locations where users are unable to switch lenses.
World’s first lens offering ultra-wide-angle 11 mm minimum focal length
EF 11-24mm f/4L USM
Feb. 2015
In addition to achieving the world’s widest angle of view starting at a minimum focal length of 11 mm, the EF 11-24mm f/4L USM effectively corrects for aberrations commonly associated with ultra-wide-angle lenses, delivering superb image-quality performance.
World’s first standard zoom lens to deliver f/2 aperture across the entire zoom range
RF 28-70mm F2 L USM
Dec. 2018
Employs a large internal mount diameter and a short back focus to realize an f/2 aperture across the entire zoom range, a feat which was considerably difficult for EF series lenses.
Reference : In pursuit of the ideal lens
The history of lenses for Canon's EOS series of interchangeable-lens cameras began in 1987 with the release of the EOS 650, the world's first autofocus (AF) SLR camera to employ an electronic lens mount, and the EF 35-70mm f/3.5-4.5, EF 35-105mm f/3.5-4.5 and EF 50mm f/1.8 lenses. The EF mount utilized by the camera and lenses not only made possible highly accurate AF, but also anticipated future technological developments including digitalization, high-speed continuous shooting, image stabilization and video recording. This forward-thinking mindset has helped support photographers for more than 30 years.
Amid the transition from film cameras to digital in the 1990s, the adoption of video recording technology for DSLR cameras in the late 2000s and the Company's entry into the video production industry the birth of the Cinema EOS System in 2012, Canon has continued to develop cameras that meet the needs of their time. Throughout this time, Canon has continued to expand the possibilities of photographic expression by producing a rich lineup of EF lenses—including zoom lenses, IS lenses, wide-aperture lenses, macro lenses and tilt-shift lenses—and a number of world-first technologies.
And now, anticipating the next 30 years of social change and technological development, Canon introduced the RF mount alongside its launch of the EOS R system in 2018. In the same year, the EOS R mirrorless camera debuted together with four RF lenses including the RF 24-105mm F4 L IS USM. Leveraging their characteristic large internal mount diameter of 54 mm and a short back focus, RF lenses enjoy greater freedom for lens design that makes possible new levels of high image quality and high performance in compact sizes. To date, a total of 19 RF lens models have been released. Going forward, Canon will continue its mission to expand users' range of photographic expression as it pursues the creation of the ideal lens.
