|
EF 300mm f/2.8L USM |
World’s first use of a lens-based Ultrasonic Motor (USM) USM technology delivers fast autofocusing thanks to its high torque and responsiveness. By converting ultrasonic vibrations into rotational energy, the technology makes it possible for quiet, smooth AF drive performance. |
Nov. 1987 |
|
World’s first use of Image Stabilizer (IS) technology Users can see the results of IS technology through the viewfinder. Delivering high precision and stability for exceptional image stabilization results, this technology expands the possibilities for handheld photography. |
Sept. 1995 |
|
|
World’s first use of a diffractive optical (DO) lens element 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. |
Dec. 2001 |
|
|
World’s first use of Subwavelength Structure Coating (SWC) SWC technology minimizes reflections by aligning countless wedge-shaped structures more minute than the wavelength of visible light on the surface of a camera lens. |
Dec. 2008 |
|
|
World’s first use of Hybrid IS, which compensates for both angle camera shake and shift camera shake Employing a newly-developed 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. |
Oct. 2009 |
|
|
World’s first fisheye lens to deliver both 180-degree diagonal angle of view and 180-degree circular fisheye The EF 8-15mm f/4L Fisheye USM lens 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. |
July 2011 |
|
|
World’s first super-telephoto zoom lens to employ an internal extender Featuring a built-in 1.4x extender, the EF 200-400mm f/4L IS USM Extender 1.4x’s lens zoom range can be expanded with a simple one-touch operation even in locations where users are unable to switch lenses. |
May 2013 |
|
|
World’s first lens offering ultra-wide-angle 11mm minimum focal length In addition to achieving the world’s widest angle of view starting at a minimum focal length of 11mm, the EF 11-24mm f/4L USM effectively corrects for aberrations commonly associated with ultra-wide-angle lenses, delivering superior image-quality performance. |
