Canon press release:

Canon celebrates significant milestones with production of 110 million EOS series cameras and 160 million interchangeable RF/EF lenses

TOKYO, June 29, 2023—Canon Inc. announced today that the company has reached two major production milestones—a cumulative total of 110 million¹ EOS Series interchangeable-lens cameras in March and 160 million² RF/EF series interchangeable lenses in May. An EOS R6 Mark II (released in December 2022) was the 110 millionth EOS series camera produced, while an RF100mm F2.8 L MACRO IS USM (released in July 2021) became the Company’s 160 millionth interchangeable lens.

Production of EOS Series cameras reaches 110 million mark through Canon’s pursuit of “Speed, Comfort and High Image Quality”

EOS, or Electro Optical System, is also the name of the Greek goddess of the dawn. Canon’s EOS system debuted alongside the EF series of interchangeable lenses in March 1987 as the world’s first fully-electronic mount system for silver halide film AF SLR cameras. During the dawn of digital SLR cameras, Canon introduced its breakthrough EOS Kiss Digital (EOS Digital Rebel or EOS 300D in other regions) in September 2003. Since that time, Canon has continued to launch a range of groundbreaking products, including the professional-model EOS-1D series and the EOS 5D series, which paved the way for digital SLR video recording. Canon’s desire to further expand the boundaries of visual expression led to its next-generation EOS R System, launched in October 2018. By striving to expand its lineup of attractive products to meet a diverse range of needs, Canon’s EOS series has gained and maintained the support of many users over the years. As a result, the company has maintained the world’s No. 1 share³ of digital SLR cameras over 20 years, from 2003 to 2022. In March 2023, Canon produced its 110 millionth EOS series camera.

Production of Canon RF/EF lenses reaches 160 million unit production milestone on the strength of advanced imaging technology

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 firsts⁴ as the Ultrasonic Motor (USM), Image Stabilizer (IS) technology, and a multilayered diffractive optical (DO) element.

With the addition of the RF Lens—which achieves unprecedented high image quality by leveraging a large aperture and short-back focus, along with a high-speed signal transmission system, that are the hallmarks of the EOS R System launched in 2018—the entire range of lenses has been expanded to include a total of 115 models⁵, expanding the possibilities of image capture. In May 2023, the Company celebrated the production of 160 million EOS series interchangeable lenses.

Refining its proprietary imaging technologies, Canon will continue to strengthen and expand the EOS series along with its RF and EF lens lineup, striving to push the frontier of imaging forward and to contribute to the further development of photographic and video imaging culture.

Canon appears to be rather active in discontinuing their EF and EF-S lenses at fast speed. Latest reports state that more lenses have been retired.

asobinet.com reports a tweet by photographer Kimio Tanaka, stating that Canon is discontinuing EF and EF-S lenses (machine translated):

CANON’s EF / EF-S lenses for SLR cameras are “low in stock” and “discontinued” at a tremendous speed (that is, production has been discontinued, and the rest is only in market stock).
Currently, about 70 are “on sale”, but about 25 of them are treated as discons. I don’t want to think of a single-lens reflex camera as a light in front of the wind, but the remaining expectation is PENTAX. I want you to do your best.

The EF 40mm F2.8 and EF 85mm F1.2L II show up as discontinued, according to asobinet.com (the latter is not in stock at B&H). it seems Canon’s stock of EF and EF-S lenses is shrinking pretty quickly. The future is the RF mount, that seems ascertained.
