Patent: Expandable LCD Display for Canon Cameras

Patent: Expandable LCD Display for Canon Cameras

By Canon Rumors | August 28, 2015 | Canon Patents

An odd patent for an expandable LCD display has appeared. You can expand the size of the LCD screen by moving the grip side of the camera.

Patent Publication No. 2015-154223 (Google Translated)

  • Published 2015.8.24
  • Filing date 2014.2.14
  • Rotatable operation unit
  • The first state is a rear LCD expands and contracts, the operating face of the operating unit faces behind
  • The second state, the rear LCD is extended, the operation surface of the operation portion faces to the right

New Tamron Prime Lenses Coming

New Tamron Prime Lenses Coming

By Canon Rumors | August 28, 2015 | Third Party Lenses

It looks like we’ll be seeing some new Tamron prime lenses very shortly.

SP 35 mm F1.8 Di VC USD (Model F012)

  • Mount Canon, Nikon, Sony
  • No VC for Sony

SP 45 mm F1.8 Di VC USD (Model F013)

  • Mount Canon, Nikon, Sony
  • No VC for Sony

Tamron definitely needs some updated fast prime lenses, and hopefully these come in well under the pricing of Sigma ART series primes. It’s also nice to see VC on some faster lenses.

EF 35 f/1.4L and EF 35 f/1.4L II MTF Comparison

By Canon Rumors | August 27, 2015 | Canon DSLR News

The optical performance difference between the two lenses looks to be quite significant if you go by the MTF chart comparison.

I had two complaints about the original 35L, the first being it wasn’t weather sealed and the second was the CA, it looks like both of those issues have been corrected. I’m looking forward to seeing if the additional weight is going to be difficult to get used to with the new lens, I did like the compact size of the first version.

Unfortunately, there aren’t many sample images  from the new lens yet, but they should start making their way to the web soon.

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 Develops New Camera-Lens Optical Element

Canon Develops New Camera-Lens Optical Element

By Canon Rumors | August 26, 2015 | Canon DSLR News

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.
