Rumour has it we can expect a NEW lens from Canon before this years out, which will include their new 'Blue Spectrum Refractive Optical Element'. According to Canon, this new BR element sets a new level in Chromatic Aberration Correction for outstanding image quality. This new BR element is due to debut in the Canon EF 35mm f1.4L II USM (Due OCT'15).
"TOKYO, August 27, 2015—Canon Inc. today announced that it
has developed a new Blue Spectrum Refractive (BR) optical element for use in
camera lenses that corrects for chromatic aberrations at an exceptionally high
level to make possible superior 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,
sandwiched between two glass lens elements to create a BR lens, will make its
debut in the new EF35mm 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's Composite Lens employing the BR optical element |
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 make
possible outstanding imaging performance by correcting for chromatic
aberrations at an exceptionally high level.
CANON RUMOURS BLOG have suggested that this NEW lens is likely to be the replacement for the Canon EF 16-35mm f/2.8L II, which we can clearly understand. Ever since the release of the Tamron SP 15-30mm f/2.8 Di VC USD, the Tamron has proven itself to be both superior in image quality & value to its Canon & Nikon counterpart.
