Nikon UK has officially confirmed increases to the prices of its D800, D800E and D4 DSLRs.

However the company says it will honor the prices on existing pre-orders placed before March 24th. Click through to read a press statement from Nikon UK.

We've updated our Canon EOS 5D Mark III preview with a selection of real world samples images and more detailed descriptions of the camera's behavior. We've shot a range of subjects under different lighting types and light levels to see how the latest 22MP performs. These shots were taken using a pre-production camera running final firmware, so may not be 100% representative of final image quality (though Canon allowing us to publish them suggests they're not far off). We're expecting a production-standard camera and will be adding studio test shots next week.

We've just got hold of Nikon's 36MP D800 full-frame DSLR and have been seeing what it's like to shoot with. We've shot it alongside the D3S to see exactly what effect trebling the pixel count has. In addition we look at the handling, its video shooting controls and how it behaves with vintage lenses. To put our studio samples in context we've also included a 40-image real-world samples gallery and a look at the camera's low-light performance. You may be surprised by the outcome.

We've written a breakdown of the photography-related features Adobe is preparing for Photoshop CS6. The beta version shows a substantially redesigned interface and a selection of new tools and enhancements. These include photographically-styled blur tools and greater support for video editing. CS6 will also include Adobe Camera Raw 7, bringing the Raw processing tool back into line with Lightroom. Read on to find out about the changes CS6 is likely to bring.

Pentax has launched the D FA 645 25mm F4 AL [IF] SDM AW wide angle lens it first announced in February 2011. The lens offers a 19.5mm equivalent field-of-view when mounted on the 645D medium format DSLR and features the company's 'all weather' designation to reflect its level of environmental sealing. The lens will be available from March 2012 at an MSRP of $4999.95/£3999.99

Facebook has added high resolution photos and full screen photo viewing. From today, the photo viewer will show the highest resolution image available, rather than offering a download link for higher-res images (up to 2048 pixels along each edge). An option to expand the photo to fullscreen has also been added. The changes also include adding a simplified version of the sRGB color profile to each image, increasing its chances of displaying color correctly.

Adobe has released a public beta version of Photoshop CS6, the industry standard image editing software. Available immediately for free download from Adobe Labs, it introduces a complete redesign of Photoshop's user interface along with auto and background save options. Other headline features include Content-Aware Patch and Move tools, additional photographic blur filters, increased video editing capability and Adobe Camera Raw 7.

We've just posted our hands-on preview of Pentax's K-01 K-mount mirrorless camera. The K-01 combines the 16MP CMOS sensor from the K-5 DSLR with a full Pentax K lens mount, to create a mirrorless camera with an enviable range of lenses already available. Of course using a full-depth K-mount also means the K-01 is also fairly bulky which, in conjunction with its unusual Marc Newson design, is likely to make it something of a love/hate camera. Read more to determine which side of that line you fall on.

Fujifilm has added more user-interface refinements to its X100 large sensor camera with firmware v1.20. The latest firmware allows the Raw button to be user-customized. It also makes it easier to set up the camera's Auto ISO behavior and built-in ND filter. The update also claims to improve AE and AF performance when shooting movies. A PDF addendum to the user manual has also been released.

Olympus has issued firmware v1.3 for its E-5 DSLR, along with the PEN E-P3, E-PL3, E-PL2 and E-PM1. The updates provide all five cameras with improved stability when using SDXC cards larger than 48Gb. Meanwhile, the E-PL3 and E-PM1 are also tweaked for improved operation when using external flashes in RC mode. The latest versions can be downloaded via the Olympus Camera Updater software.

Just Posted: studio test samples from the Nikon D800. We're running the 36MP D800 through our standard set of studio tests and have completed the shots of our test scene. These have been appended to the D800 preview and include all the Raw files for download. You can also access the shots from other reviews or the standalone comparison tool.

Western Digital has refreshed its 'My Passport' range of portable hard drives, including a 2TB version. The redesigned drives come in a choice of five sizes and five colors and come bundled with WD's own automatic backup and security software, to allow secure data use on-the-move. All the models, which start at a cost of $129.99, feature USB 3.0/2.0 connection for fast data transfer.

Images of a Panasonic GF5 have begun to appear on various websites. First an Instagram image of a camera, looking a lot like a GF3 refresh, appeared on the site of an Hong Kong actress/model Angelababy, who just happens to have promoted Panasonic products in the past. Plausible manufacturer product shots (consistent with the Instagram image), have also appeared. We won't speculate about specifications, but it seems reasonable to assume there's another GF on its way. (via 43 Rumors)

Phase One has knocked around 25% off the price of its Capture One 6 Raw processing software. It has also increased, to 60 days, the free trial period for both Capture One Express and the more fully-featured Capture One Pro. The company's updated website shows Capture One Pro costing $299/€229 and Capture One Express reduced to $99/€69.

Just published: studio test samples from the Olympus OM-D E-M5. We've just received a production-standard E-M5 so have rushed it into the studio to shoot our standard test scene. These shots have been added to our preview, but can also be accessed from other camera reviews or from the standalone comparison tool. Have a look to see how it stacks up against its rivals, or download the Raw files to subject them to your favored workflow.

Carl Zeiss has announced the Distagon T* 2,8/15, a super-wide-angle lens for Canon EF and Nikon F mounts. The lens can focus from just 25cm (10") and offers a 110 deg; field of view when mounted on a full-frame camera. It uses aspherical elements and abnormal partial dispersion glass in order to control distortion and chromatic aberration. It features an integrated lens hood and accepts 95mm threaded filters. It will be available from May for an MSRP of: €2,148 or US$2,948.

'Once the cloud computing era truly dawns, a non-connected device will be meaningless,' says Samsung Imaging's Sales & Marketing VP, Sunhong Lim. Speaking to dpreview, he suggested a combination of customer expectations and wireless carriers' desire for greater data usage will encourage compact cameras to become ever-more-connected devices. Indeed Lim believes that desire might even see telecomms networks help pay for your next camera. Click here to read his ideas about connected cameras.

Apple has added Raw support for eight additional cameras, including Nikon's D4, Canon's G1 X, Sony's NEX-7 and the Samsung NX200. Digital Camera Raw Compatibility Update v3.10 also brings Panasonic GX1 and FZ35/38 support to Aperture and iPhoto, taking the number of cameras covered to 260. The update requires Mac OS X 10.6.8 or Lion 10.7.1 or later.

Samsung has refused to confirm reports that it is working on an Android-based camera, only to say it is looking at the idea. The non-denial, which says 'it is something we are monitoring,' comes in response to reports from tech website Engadget that it is considering an 'open' camera operating system. However, while the site goes on to speculate that Android makes sense, based on its parent company's use of the OS on its smartphones, we think there are other reasons for Samsung to use Android.

Leica has announced it will bundle Adobe Photoshop Lightroom 4 with many of its cameras. The latest version of Adobe's raw processing and management software offers extensive support for Leica cameras and lenses. It will be included with future purchases of the S2, S2-P, M9, M9-P, X1 and D-Lux 5 cameras.

Software maker DSLR Guru is oftering a 50% discount on its ProFX pack of presets and film emulation plugins for Adobe's Lightroom 3 and 4.

The pack would usually cost £19.99 but will be available for £9.99 until the end of March 2012.

We've been able to borrow a pre-production Sony A57 and have prepared a preview that includes both real-world and studio sample images. Many of the camera's features - 16MP sensor, 1.44m dot LCD viewfinder are familiar but they all come wrapped in a larger, more comfortable body, powered by a larger battery. We've shot samples in a series of the A57's modes, including its Auto Portrait Selection Framing mode - in which the camera crops an image with a face in, in-accordance with the rule-of-thirds.

Sony has announced the SLT-A57, a replacement for the original A55 fixed-mirror, electronic viewfinder DSLR. The A57 still features a 16MP sensor and LCD viewfinder but incorporates them into essentially the same body as the more expensive A65. Use of the latest Bionz processor means the A57 offers a wider-than-ever selection of photographic features and image processing modes. Updated with more information about the optional HVL-LE1 video-lighting LED panel.
