The Canon 35mm f/1.4L was a good design, but showed serious limits on modern digital. Along comes the new “II” design with some intriguing new optical prowess.
At about $1799, the Canon EF 35mm f/1.4L II USM looks to take care to offer improved image quality, particularly color correction:
The EF 35mm f/1.4L II USM from Canon is an L-series prime wide-angle lens featuring Blue Spectrum Refractive Optics and a maximum aperture of f/1.4, making it ideal for shooting in low-light situations and for controlling depth of field.
Two aspherical elements and one Ultra Low Dispersion (UD) element combine with the BR element to control chromatic aberrations and color fringing for increased clarity and sharpness.
A Subwavelength Coating has also been applied to reduce ghosting and lens flare for greater color accuracy and contrast.
The Ultrasonic autofocus motor (USM) provides fast and near-silent AF operation. Full time manual focus override enables precise manual focus even when in AF mode.
- Prime wide-angle lens is designed for full-frame Canon EOS DSLRs, and can also be used with APS-C-sized sensors where it will provide a 56mm equivalent focal length.
- The Blue Spectrum Refractive Optics element refracts shorter wavelengths of the visible spectrum (blue light) in order to significantly reduce chromaticaberrations and color fringing.
- A pair of aspherical elements and one UD element also help to control aberrations and distortions for sharper, clearer image quality.
- Subwavelength Coating minimizes surface reflections, ghosting, and flare for increased contrast and color fidelity.
- The Ultrasonic Motor offers fast and quiet autofocus performance and also permits full-time manual focus control by simply rotating the focusing ring.
- A minimum focus distance of 11" with a 0.21x maximum magnification benefits working with close-up subjects.
- Fluorine coatings on the front and rear surfaces help reduce fingerprints and smudging.
Featuring the L-series designation, this lens is also dust and moisture-resistant for use in trying conditions.
- A nine-blade aperture provides smooth and pleasing out-of-focus areas in selective focus images.
- 14 elements in 11 groups
- Minimum Focus Distance 11.02" (28 cm) at 0.21X = 1:4.7
- Ultrasonic Autofocus Motor
- Weather-Sealed Design
- Rounded 9-Blade Diaphragm
- 72mm filter size
- Approx Weight 1.67 lb (760 g)
Blue spectrum optics
I’m baffled by “organic” optical materials. The term does not apply to glass, so maybe it really means organic—some new compound.
The violet/blue spectrum is very hard to control (hence longitudinal chromatic aberration typical present as a violet/purple halo), so this is an interesting development.
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.
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.
