Canon Announces the EF 35MM f/1.4L II USM Lens with New Blue Spectrum Refractive Optics

canon_EF35mm-14-II-USM.jpegCanon has announced the new EF 35mm f/1.4L II USM, the first lens to feature what Canon is calling Blue Spectrum Refractive Optics (BR Optics) technology, designed to achieve a higher degree of Chromatic Aberration Correction for superb image quality.

The new BR Optics uses a new organic optical material with unique properties that refract more blue light in the short wavelength spectrum to better control color fringing when compared to other optical technologies like UD Glass and Fluorite, allowing images with great contrast and color fidelity.

This image shows how BR Optics works to reduce Chromatic Aberrations:

The new 35mm f/1.4 II USM lens will have two aspherical elements and one UD element in a 14 element, 11 group optical design.  This new lens will also feature Canon's SWC (Sub-Wavelength Structure Coating), to help reduce flare and ghosting, and will be able to focus as close as approximately 11 inches.    This lens also features Canon's USM (Ultrasonic Motor) Focusing Technology with full time manual focus override available, even when the lens is set to AF Mode.

Canon also says that this new II version will offer greater durability over the previous 35mm f/1.4L USM lens, and is designed to be highly resist to dust and water; thanks to the addition of a flourine coating on the front and rear surfaces - making it ideal for outdoor photography, even in harsh conditions. The high-grade design of the lens provides users with a substantial and luxurious feel, as well as optimal operability.  In addition, a fluorine coating on the front and rear lens surfaces helps to repel liquids and dust particles, and makes the lens easier to clean.

Canon indicates that the new EF 35m f/1.4L II USM lens will be available in October 2015, for an estimated retail price of $1,799.00

CANON U.S.A. INTRODUCES NEW CANON EF 35MM F/1.4L II USM LENS


New L-Series Lens is First to Feature Canon's Proprietary Blue Spectrum Refractive Optics -
That Achieves a Higher Level of Chromatic Aberration Correction For Superb Image Quality

MELVILLE, N.Y., August 27, 2015 - Canon U.S.A., a leader in digital imaging solutions, today introduced the new EF 35mm f/1.4L II USM lens for EOS system cameras - a wide-angle fixed-focal-length Canon EF lens that is the world's first* to utilize the Company's newly-developed and exclusive Blue Spectrum Refractive Optics (BR Optics). This new optical technology utilizes organic material newly developed by Canon to achieve a higher level of chromatic aberration correction than other existing technologies resulting in outstanding high-quality imaging performance.


"As the world leader in production of interchangeable lenses, having produced over 110 million EF lenses since 1987, it is with great excitement that we now introduce a revolutionary new technology to add to Canon's unequaled optical heritage when it comes to chromatic aberration correction," said Yuichi Ishizuka, president and COO of Canon U.S.A., Inc. "We continually strive to achieve the ideal lens performance, which has driven the development of Blue Spectrum Refractive Optics, found in the new EF 35mm f/1.4L II USM lens. This technology is yet another 'first' in optical design introduced by Canon to enhance the performance of our lenses for our customers."


Canon's proprietary Blue Spectrum Refractive Optics (BR Optics) incorporate a new organic optical material with unique anomalous dispersion characteristics for use in camera lenses. The molecular design of BR Optics refracts blue light (short wavelength spectrum) to a greater degree than other existing optical technologies including UD glass, Super UD glass and Fluorite, to control color fringing as effectively as possible. When placed between convex and concave lens elements made from conventional optical glass materials, BR Optics help to produce sharp images with outstanding contrast and color fidelity by thoroughly reducing axial chromatic aberration.


In addition to BR Optics, the new lens incorporates two aspherical elements and one UD glass element in a 14 element, 11 group optical formula. The EF 35mm f/1.4L II USM lens also features Canon's proprietary Sub-Wavelength Structure Coating (SWC), applied to the rear surface of the first and second aspheric lens elements to help combat flare and ghosting caused by light rays entering the lens at a large angle of incidence. The lens also offers best in class minimum focusing distance at 0.28m (approximately 11 inches) resulting in an increased maximum magnification of 0.21x - ideal for capturing close-up subjects. Autofocusing is swift and virtually silent due to a rear-focus optical system and Canon's original Ring USM focusing motor. Full-time mechanical manual focusing is also available even when the lens is set to AF mode.


The Canon EF 35mm f/1.4L II USM lens features improved durability over its predecessor. As with all L series lenses, this new lens is highly resistant to dust and water ─ making it ideal for outdoor photography, even in harsh conditions. The high-grade design of the lens provides users with a substantial and luxurious feel, as well as optimal operability. In addition, a fluorine coating on the front and rear lens surfaces helps to repel liquids and dust particles, and makes the lens easier to clean.


Pricing and Availability

The new Canon EF 35mm f/1.4L II USM lens is compatible with 72mm filters and will be supplied with Lens Hood EW-77B and Lens Pouch LP1219. It is scheduled to be available in October 2015, for an estimated retail price of $1,799.00.

CANON DEVELOPS NEW CAMERA-LENS OPTICAL ELEMENT THAT ENABLES EXTREMELY HIGH LEVELS OF CHROMATIC ABERRATION CORRECTION


CANON DEVELOPS NEW CAMERA-LENS OPTICAL ELEMENT THAT ENABLES EXTREMELY HIGH LEVELS OF CHROMATIC ABERRATION CORRECTION


MELVILLE, N.Y, August 27, 2015 - Canon U.S.A., Inc., a leader in digital imaging solutions, today announced that its parent company, Canon Inc., has developed Blue Spectrum Refractive (BR), a new optical element for use in camera lenses that corrects chromatic aberrations at an extremely high level to achieve superb imaging performance.


The new Canon-developed BR optical element offers characteristics that significantly refract blue light, which lies within the short-wavelength range, to achieve impressive levels of chromatic aberration correction for outstanding imaging performance. The BR optical element, positioned between two glass lens elements to create a BR lens, will make its debut in the new EF 35mm f/1.4L II USM wide-angle fixed-focal-length lens, which is scheduled to go on sale in October 2015.


Natural light, or white light, comprises a spectrum of wavelengths, or colors, each of which realizes a unique refractive index when passing through a lens. As all colors do not converge on the same point, this disparity causes chromatic aberrations, or color fringing, to occur in an image.

Canon develops optical elements by reviewing organic optical materials, beginning with the design of molecular structures, with the aim of achieving optimal chromatic aberration correction that suppresses color fringing. With the successful development of the BR optical element, which offers unique light-dispersion characteristics that significantly refract blue light--a wavelength that, until now, had proven particularly difficult to converge to a specific focal point--Canon is able to develop lenses that result in outstanding imaging performance by correcting chromatic aberrations at an exceptionally high level.
