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…
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.
A few months ago we posted this project for the KOBRA Flash Modifier System, and unfortunately it did not reach its funding goal, this time it has. This is a great time to take advantage of the sale price for the Kickstarter campaign, you can save up to 30% until the campaign ends on June 9, 2018. Check out the KOBRA flash modifier now!
KOBRA Flash Modifier Provides Photographers Exceptional Design and Function on Kickstarter
KOBRA takes a bite at the flash modifier market with a relaunch on Kickstarter offering an attractive design and price
Irvine, CA – Red Tusk, LLC. announced the relaunch of their KOBRA Flash Modifier on Kickstarter with exclusive features and competitive pricing.
The KOBRA was designed to give photographers an effective modified flash solution that is lightweight, flexible and with a sleek design. Professional photographer, Paul McKelvey, conceived the idea for KOBRA through his disappointment in the current market. McKelvey said, “I have used all the ‘on camera flash’ modifiers that are available and have been unsatisfied with the results. I decided to stop complaining and make my own.”
The new Kickstarter campaign includes the improved KOBRA Band, a high-grade, flexible silicone that is not affected by high or low temperatures. The new design features vent holes to allow air to circulate over the flash head and prevent the potential for overheating.
