New Gear: 11-16mm Tokina AT-X 116 Pro DX II

An update of the already popular 11-16mm from Tokina, the DX II packs a focussing motor so it'll work with all Nikon bodies.

Tokina has just announced an updated version of their well regarded 11-16mm Pro DX, one which brings more functionality to more camera bodies. Dubbed the Tokina AT-X 116 Pro DX II, the new lens has only officially been announced in Japan, but shouldn't be too long before it heads to western markets. For now, it appears to be for Canon and Nikon APS-C cameras, and the big change is that it comes packing  a 'Silent Drive-Module' (SD-M) focus motor. That's right, if you have a Nikon SLR without a built-in focusing motor, then you can still use AF on this new Tokina lens. It also features new coatings, and faster autofocus.

The Japanese announcement pegs the Nikon version of the lens is set to launch in March, and the Canon in July, and DPReview's USA contact says April and August respectively. Its predecessor was also available for a Sony mount, so we'll see if Tokina goes that way with the new one, too.

The big talking point on this lens is the price. With an announced sticker of a whopping  ¥90,000 (almost $1200) that's putting it into very high-end territory. In fact, the original DX lens is going forjust $609 with an MIR. While that is an extremely high asking price, it's the same as the official list cost of the original, so hopefully the new one will drop to a similar level quickly.

The Most Amazing High Definition Image of Earth Ever,' Says NASA

Published on 26/01/12 in the section of Publications

By viewAt.org Team

NASA has released a new Blue Marble image, showing the United States of America. According to them, it's the "most amazing, highest resolution image of Earth ever." Blue Marble 2012 bests the 2010 edition and the original one.

The original one—the default background image in the iPhone—was 2048 x 2048 and was made combining different images. The 2010 edition was created with data from NASA's Terra satellite. But Blue Marble 2012 uses the latest data from NASA's newest Earth-observing satellite: Suomi NPP. It's made from several passes taken on January 4, 2012 using the satellite's Visible Infrared Imager Radiometer Suite instrument (VIIRS).

You can download it at a whooping 8000 x 8000 pixels. The detail at that resolution is amazing, but I recommend 1024 x 1024 for all your tablet, phone and computer background needs. [NASA Goddard Flickr]

Sony Develops New “RGBW Coding” and “HDR Movie” Functions

Published on 23/01/12 in the section of Presentations

We think this could be great news for our community. Do you think it would be a good movement for Sony?. Here you´ve got the press release they did today. Also you will see a video with the funtions.
Tokyo, Japan - January 23, 2012 - Sony Corporation (“Sony”) today announced the development of two CMOS image sensor models designed for use in smartphones and other devices. They are equipped with Sony's unique “RGBW Coding” function which allows images to be captured with low noise and high picture quality even in low-light conditions. They also contain Sony's “HDR (High Dynamic Range) Movie” function which allows brilliant color to be captured even in bright settings. Sony has also developed a model with built-in signal processing functionality, an element that usually requires external embedment.
  Sony has successfully developed new stacked CMOS image sensor technology that realizes higher image quality and superior functionality in a more compact size. The three newly developed next-generation back-illuminated CMOS image sensor models will be the first to utilize this technology. Samples will begin to successively ship starting March 2012.
1. Sony's unique “RGBW Coding” function enabling clear shooting in dark rooms or at night
  The built-in “RGBW Coding” function which adds W (White) pixels to the conventional range of RGB (Red-Green-Blue) pixels has realized higher sensitivity, enabling high-quality shooting with low noise even in dark indoor or night settings.
  While the addition of W (White) pixels improves sensitivity, it has the problem of degrading image quality. However, Sony's own device technology and signal processing realizes superior sensitivity without hurting image quality. Furthermore, while the individual pixels of the newly developed models are extremely minute at 1.12μm, the incorporation of the “RBGW Coding” function has realized a SN ratio (signal-to-noise ratio) equivalent to that of a unit pixel size of 1.4μm under conventional methods, which in turn has enables the image sensors to achieve a higher resolution at a more compact size.
  The new models are also able to output signals through the conventional RGB method, thus there is no need to change the signal processing adopted in existing devices.

2. “HDR (High Dynamic Range) Movie” function which enables brilliant colors to be captured even in bright settings
  The built-in “HDR Movie” function enables brilliant colors to be captured even in settings with a wide range of light including bright light.
  Typically, when shooting with differing light levels, such as an indoor setting against a bright outdoor background, there can easily be blocked up shadows for dark areas or blown out highlights for bright areas. Such phenomena are a result of the combination of low-light and bright-light which have different optimal exposure conditions in the same shot. This function reduces this by setting two different exposure conditions within a single screen shooting and conducts the appropriate signal processing for the captured image information under each optimal exposure condition. This process generates an image with a broad dynamic range and enables shooting of both the background and subject matter with brilliant colors even in a bright environment.
