Do you want to know everything about camera sensors? Are you ready for some geek talk? Then do not miss this 13 minutes video by Filmmaker IQ on YouTube. The science of camera sensors explained in an exciting lecture that explains what it needs to capture a digital image.
Jared Polin posted a 14 minutes video where he reviews all the news and technological innovations presented by Canon at their Canon Expo 2015 in NYC. If you missed the event (it’s over now) and our coverage, then Polin’s video is right for you. Everything from the 250 and 120 megapixel sensors to the ISO 4.5M camera and the 8K video camera and displays is overviewed in a funny and entertaining way.[via FroKnowsPhoto]
Blue Refractive (BR) optical elements are employed on the new Canon EF 35mm f/1.4L II lens.
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.
A definitely interesting and pretty technical article about the Canon EOS 5Ds by Luminous Landscape. The 5Ds performance from the point of view of how much the 50MP matter when it comes to print performance. Comparison with the EOS 1Ds Mark III is discussed.
The article is not easy to sum up. It comes with sample pics, pixel peeping, and more in-depth analysis Giving it a try with a quote:
[…] the 5Ds images are notably superior in resolution, but when it comes to making prints there is an important consideration. Not one of the half dozen non photographers I showed the prints to mentioned detail in the images. When asked for differences, most popular was spotting the slightly different view, next up was that the brickwork was ‘a bit redder’ in one print.
That’s not the whole story. Head over to LL for the article.
