Apple patents system for disabling cameras in no-photography areas

by on Jun.30, 2016, under Reviews

Apple has been awarded a patent that describes a mobile camera technology that can interpret infrared signals, which could then be used to disable the camera from recording at events like concerts, among other things.

An infrared transmitter would send encoded data to the device, which would be processed by the phone. Depending on the application, the device may temporarily disable its built-in camera in locations where photography and video capture are forbidden, for example music venues, classified company areas or museums. With the system activated a ‘RECORDING DISABLED’ message would pop up on the smartphone screen when the user tries to take a photo or video. The patent even mentions the ability to add a watermark to any images or video captured when certain infrared signals are detected. 

The patent also describes use of this technology to provide additional information or visuals in a different scenario: for example, an art gallery. Pointing a smartphone camera at an IR transmitter positioned next to a painting could provide more information on the device’s screen about the artwork. The patent also mentions applications in retail environments.

There is understandably some concern about how and where such systems would be implemented. Arguably, most people would be fine with concert venues protecting the intellectual property of their acts or companies preventing industrial espionage, but there are concerns that the technology could also be used to undermine the freedom of the press. As usual, the existence of a patent does not necessarily mean we’ll ever see the final product, but in this case it might be worth at least keeping an eye on how the idea is being developed further. You can read the full patent document on the USPTO website.

Meyer-Optik Goerlitz launches 3-element 95mm F2.6

by on Jun.30, 2016, under Reviews

German lens manufacturer Meyer-Optik Goerlitz has announced a portrait lens that it claims has unique coatings to reduce flare. The Trimagon f2.6/95 is the latest in a line of lenses that the company has produced that use only three elements in the design. While the 100mm and 50mm Trioplan lenses were produced for their distinctive retro bubble-effect bokeh this Trimogan is ‘a dynamic modern lens’ according to the company. Meyer-Optik says a unique coating has been used to reduce flare and the glass used for the three elements is from the German company Schott and Japan’s Ohara.

The company claims the resolution of the lens makes it suitable for use on cameras with 60MP or more. The optical design is based around full-frame sensors, but versions with mounts for smaller formats are listed as being available.

Like all Meyer-Optik lenses, the Trimagon offers manual focus only, and its ‘distinctive’ bokeh and rounded out-of-focus highlights are helped by the use of a 15-bladed iris.

The lens is available now as it has already been on sale in Germany, and it is offered with mounts for Canon, Nikon, Fuji X, Sony E, Micro Four Thirds and Leica M. It costs $1699/€1699. For more information see the Meyer-Optik Goerlitz website.

Atlanta, GA – June 30, 2016 — Meyer-Optik Goerlitz announced today the availability of its new portrait lens, the Trimagon f2.6/95, in the United States and worldwide. Aimed at professional photographers, the Trimagon 95 uses a unique coating and design that delivers sharp images with minimal reflections to preserve skin tone. The triplet architecture 15-blade design adds Meyer Optik’s trademark artistic bokeh to Trimagon 95 images. ‘While the Trioplan 100 restored Meyer-Optik’s long lens to the artistic photography market, the Trimagon 95 provides professionals a dynamic modern lens that delivers extraordinary portraits and natural-looking photographs,’ said Dr. Stefan Immes, CEO, Meyer-Optik Goerlitz. ‘The remarkable nature of the lens is its rendering of secondary light, specifically providing realistic reflections of the finest structures.’

As with all Meyer-Optik lenses, the Trimagon f2.6/95 is 100% handmade in Germany. All Trimagon f2.6/95 lenses feature the best components and manufacturing processes, and undergo a rigorous inspection process with strict tolerance limits. The end result is a superior high-end lens for discerning photographers.

SanDisk says its two new microSD cards are the world’s fastest

by on Jun.30, 2016, under Reviews

SanDisk has announced a pair of new 256GB microSD cards: the SanDisk Extreme microSDXC UHS-I card and the Ultra microSDXC UHS-I Premium Edition card. These are the fastest microSD cards in the world, according to SanDisk, with the Premium Edition also ‘optimized for mainstream consumers.’ The cards are intended for action cameras, drones, smartphones and other gadgets with demanding storage needs.

The 256GB Extreme card is the fastest of the two, offering transfer speeds up to 100MB/s (compared the Ultra’s 95MB/s max transfer speed) and write speeds up to 90MB/s. SanDisk presents the Extreme model as being ideal for UHD video recording, saying the card can hold up to 14 hours of 4K video. The Ultra version, meanwhile, is better suited to lower resolutions, and can store more than 24 hours of Full HD video.

In addition, both microSDXC cards can withstand extreme temperatures and are waterproof, shock-proof, and x-ray-proof. Both are compatible with SanDisk’s Memory Zone Android app. The company will launch the Ultra Premium Edition card globally in August for $149.99, and the Extreme card globally in the fourth quarter of this year for $199.99.
