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 Read more…
Jared Polin has completed his review of the Canon EF 85mm f/1.4L IS, and finds out if this is a better option over the Canon classic, the EF 85mm f/1.2L II.
Personally, I sold my EF 85mm f/1.2L II after using the EF 85mm f/1.4L IS for a few weeks. The advantages of the new 85mm lens such as IS, faster AF, better built quality, and lighter weight were just too much for me to overlook.
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.
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.
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.
