Patent: More Work Being Done on Organic Sensors

By Canon Rumors | May 24, 2018 | Canon Patents

Are organic sensors the next big thing in sensor technology? They could be. Canon along with other companies continue to put resources into their development

US Patent 20180138432 from Canon News:

Canon continues to research organic photo electric elements, this one goes into a little more details, and discusses an actual sensor more so than prior patent applications. Read more…

Patent: Diffractive Optics Element Improvements

Patent: Diffractive Optics Element Improvements

By Canon Rumors | May 24, 2018 | Canon Patents

We continue to see new patent applications for diffractive optics technology. We’re all still waiting to see if the EF 600mm f/4 DO IS will become an actual consumer product, or if Canon is going to take things in a different direction.

From Canon News:

Canon describes how to manufacturer a diffractive optical element with a refractive resin component attached to it to further reduce chromatic aberrations.

From US Patent Application 20180143350:

in a refractive optical system using the refraction of light, lenses formed from glass materials having different dispersion characteristics are used together in combination to reduce the chromatic aberration. For example, in the case of an object lens of a telescope or the like, a glass material having low dispersion and a glass material having high dispersion are used in combination as a positive lens and a negative lens, respectively, to correct the chromatic aberration which appears on the axis.

The goal of diffractive optics lenses is to reduce the physical size of the lenses. This could help in a couple of areas such as smaller and lighter supertelephoto lenses and to reduce the size of longer fast lenses for full frame mirrorless applications.

ZEISS Announces New High-End Cinema Lens Family, ZEISS Supreme Primes

ZEISS Announces New High-End Cinema Lens Family, ZEISS Supreme Primes

By Canon Rumors | May 24, 2018 | Third Party Lenses

With its 13 high-speed, full-frame, prime lenses for high-quality film productions, ZEISS is focusing on maximum quality, low weight, and significant versatility when it comes to creating superb visual imagery.

ZEISS has introduced a new family of high-speed lenses for high-end film production: The ZEISS Supreme Prime family consists of 13 lenses with fixed focal lengths between 15 and 200 millimeters, the majority with a maximum aperture of T1.5. “The lenses are designed for film productions of an extremely high quality,” says Christophe Casenave from ZEISS. “They are perfect for high-budget advertising or feature films, for example.” ZEISS Supreme Primes are designed to cover cinematic large format camera sensors and are compatible with all of the latest camera models, such as the Sony Venice, ARRI Alexa LF, and RED Monstro. According to Casenave, the versatility of the Supreme Prime lenses to create different visual looks is due to the gentle sharpness, the aesthetic focus fall-off and elegant bokeh. The lenses are extremely flexible and can be used equally well for science fiction thrillers as well as for dramas.

Three Sensors Being Tested for Canon Full Frame Mirrorless? [CR1]

Three Sensors Being Tested for Canon Full Frame Mirrorless? [CR1]

By Canon Rumors | May 24, 2018 | Canon DSLR Rumors

It’s no secret that Canon is hard at work on prosumer mirrorless cameras, including at least one full frame mirrorless camera.

We’re told that three sensors are being tested in various camera body configurations, each with a different pixel count. The source claims that 24mp, 28mp and 36mp sensors are being used.  There is no mention if these are all new sensors or if they are modified versions of current image sensors.

We do find it interesting that these sorts of things are being talked about, but we still don’t have not confirmed what sort of mount solution Canon is going to come up with. As we saw this past week, Canon has patented a dedicated full frame mirrorless optical formula, which tells us we’re getting a new EOS M mount for full frame sensors.

More to come….

Supertelephoto Lens Updates Are Getting Closer [CR1]

Supertelephoto Lens Updates Are Getting Closer [CR1]

By Canon Rumors | May 23, 2018 | Canon Lens Rumors

Updates to Canon’s line of “big white lenses” is getting closer we’re told. Some of these new lenses will be present at the World Cup in Russia, which begins on June 14.

We generally assume the “big whites” as the following lenses.

  • EF 200mm f/2L IS
  • EF 300mm f/2.8L IS II
  • EF 400mm f/2.8L IS II
  • EF 500mm f/4L IS II
  • EF 600mm f/4L IS II
  • EF 800mm f/5.6L IS

We weren’t told which lenses would be in testing, but we highly doubt all of these lenses would be tested at World Cup games. It makes sense that 300mm to 600mm lenses could potentially be used.

If you’re watching the matches, keep a close eye on the sidelines.
