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.

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.

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.

Nikon USA has defended its decision to stop supplying spare parts to companies outside its authorized service network. Its intention is to deliver 'the best service experience to the customer,' says David Dentry, General Manager of Customer Relations at Nikon Inc, explaining that the complexity of modern cameras and the need for specialist analysis and calibration tools meant that repair attempts by ill-equipped retail or unauthorized repair shops could end up causing delays, increase the cost and risk voiding the camera's warranty. However, an independent service center we spoke to said its statements misrepresented the situation and is likely to mean small repairs take longer.

Fujifilm has released a statement explaining the causes of the 'white disc' blooming issue that affects certain images shot with the X10 high-end compact.

It encourages X10 and X-S1 owners experiencing 'the white disc phenomenon' to contact their local Fujifilm service center.

First released for Android, Adobe recently unveiled an iPad-targeted version of Photoshop Touch for Apple's iOS. Boasting support for layers and featuring familiar Photoshop effects and filters, Photoshop Touch is one of the best-specified image manipulation apps available, but does it live up to its promise on the world's most popular tablet? Joanne Carter of theappwhisperer.com puts it through its paces. 

We've just received an Olympus OM-D E-M5 that we can use to publish sample images and have shot an ISO sequence. We aim to bring you a real-world samples gallery in a few days time, but to whet your appetite we've prepared a quick series of studio-based shots showing how the camera behaves under the challenge of low-level tungsten lighting at all ISOs. Olympus describes our sample as 'initial production' and it's running firmware version 1.0, so these should give a pretty good idea of what you'll be able to expect from the camera when it hits the shops.

The BBC has an interesting short interview with Magnum photographer Elliott Erwitt, in which he talks about looking for sequences of shots, rather than one-off photos. The video coincides with the launch of his book 'Sequentially Yours' and looks at how a series of photos can sometimes tell more of a story than a single shot in isolation.

In this first iteration we've made it easy browse reviews, news stories, articles and previews. Forums and commenting support will come in later versions. However, although we think m.dpreview will make it easier to enjoy the site, we've placed small links at the bottom of every page to swap between the mobile and desktop versions.

Alongside Lightroom 4, Adobe has release the latest release candidate of Adobe Camera Raw.

Nokia's developer website is showing the 41MP 808 PureView as being available globally, with the exception of North America. However, Windows Phone website WPCentral is reporting that the company will bring its PureView technology to a phone running Windows Mobile - something likely that become truly global product.

The 15x3MP Foveon sensor-equipped DP1 Merrill and DP2 Merrill, along with the Digital Neo 19mm F2.8 and 30mm F2.8 lenses for Micro Four Thirds are all on show, so we decided to dig a bit deeper.
