The World’s First f/1.8 Constant Aperture Lens Will Stalk Light Like Nothing Else

Sigma has just announced its new 18-35mm f/1.8 lens—the world's first ever lens to offer a fixed f/1.8 aperture throughout its zoom range. This thing will stalk light like you would not believe.
Designed for DSLRs with APS-C sized sensors, this lens is the first to achieve a maximum aperture of f/1.8 throughout its zoom range. In the past the widest aperture a zoom lens has been capable of achieving has been f/2.8—in contrast, this Sigma lens offers more than a stop of extra light.

The upshot? While people have often had to carry a prime lens to achieve f/1.8 in the past, now that kind of light gobbling should be possible with a single lens. Indeed, Sigma claims that it's been designed as a standard, everyday lens.
Sigma admits that producing the lens was tough—development was fraught with issues of distortions and aberrations—but it clearly got there. Elsewhere, there's internal focusing and zooming, a special Super Multi-Layer Coating to reduce flare, and a minimum focusing distance of 28cm. No word yet on pricing or availability yet—but it probably won't come cheap. Via: TechRadar

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Flexible displays are the Future of IT Industry! A part from 4k and smart home appliances, the CES 2013 saw a lot of attention being drawn towards bendable, flexible displays. The elasticised display idea isn’t something new as we have seen hoards of device concepts being crafted around flexible, bendable and even foldable displays. These concept devices give us a futuristic feel, be it a flexible phone to be worn around the wrist or a phone that opens up to turn into a tablet or PSP-like device. But how far is this future? Nokia has been toying with the idea ever since we remember. The technology sounds very fascinating and the possibilities and the extent to which bendable displays could be used are vast and leave us spellbound. However, these have always been concepts and we haven’t seen any device materialise in the real world. There have been several technologies that were conceived in these years and all have been put to their practical use. But the bendable d
