Firmware version 1.01 offers contrast adjustment option for the cameras' LCD displays as well as 'stability improvements'. The updates are available for immediate download from the company's website - click through for download links. 

The Lumia 920 is Nokia’s current flagship smartphone and the second phone graced with the Finnish manufacturer's PureView branding. Unfortunately this is not the same, large-sensor 'PureView' concept as the 808 but a fast F2.0 lens, optical image stabilization and true multi-aspect-ratio support still make the Lumia 920, at least on paper, look like a very promising connected imaging device. Peter Ferenczi has tested the phone for Connect, click through to see how he got on.

DxO Labs has released the latest version of its DxO Optics Pro software, with more than 10,000 camera and lens correction combinations now supported. The latest version, v8.1.2 or the more expensive Elite edition adds support for the Sony Cyber-shot DSC-RX1 full-frame, fixed-lens camera as well as Canon's EOS 6D. Meanwhile both the Elite and Standard versions gain support for the Nikon 1 V2. With this release DxO has achieved its stated target of offering 10,000 optics modules. Both editions are available with a 33% discount until the end of January 2013.

Just Posted: Our review of the Canon PowerShot SX50 HS. Canon's latest superzoom, the SX50, features a 24-1200mm (equivalent) lens and a feature set that compares well to its competition, in what is now one of the most competitive segments of the compact camera market. Specifications include a 12MP CMOS sensor, 2.8" fully-articulated LCD screen, Raw capture and full manual control. Is this the travel camera enthusiasts have been waiting for? Read our review - created in collaboration with Jeff Keller of The Digital Camera Resource Page - to find out. 

The latest version of Capture One brings support for Fujifilm's X-Trans sensors - something we noted other software struggled with, when we reviewed the X-Pro 1. Beta versions of the software have caused a lot of excitement for X-Pro1 and X-E1 users finally looking to get the most from their photos. Do the results live up to the expectation? We had a look.

CameraMator is one of the more interesting photographic gadgets we saw at CES this year. It's a Kickstarter-funded Wi-Fi tethering accessory for Canon and Nikon DSLRs that gives remote live view, camera triggering and image download to Android and iOS devices. The device itself mounts on the hot shoe and can connect to a local Wi-Fi network or peer-to-peer with the mobile device. The standard USB lead that comes with the camera gives the unit access to the camera's key features. Find out more over on Connect.

Specialist accessory manufacturer Metabones and optics company Caldwell Photographics have jointly announced the 'Speed Booster', a lens adapter for mounting SLR lenses on APS-C and Micro Four Thirds mirrorless cameras that reduces the focal length by a factor of 0.71x and increases the maximum aperture by 1 stop. The Speed Booster also promises sharper images compared to using the lens with a simple adapter. The first version will allow use of Canon EF lenses on Sony NEX bodies, and will be available this month from Metabones' web site for US$599. Support for additional lens mounts (including Nikon F) and camera systems (including Fujifilm X and Micro Four Thirds) is also planned.

Phase One has announced that it has updated its Capture One Pro raw conversion software to version 7.0.2. This includes support for several additional cameras, including the Fujifilm X-Pro1, X-E1 and XF1, Canon EOS 6D and EOS M, Sony SLT-A57 and NEX-5R, and Olympus XZ-2 iHS. The update is available immediately from the company's website, as a free download for users of Capture One 7.

This year's Consumer Electronic Show is packed with exhibitors, industry analysts and press, all eager to see, touch and talk about this years' hottest electronics. As well as countless televisions, tablet computers and portable electronics, a lot of cameras get announced at CES, too. Here's a quick rundown of some of the most interesting new models on show at this year's event.

Lenovo might not be the first name that springs to mind when you think of smartphones but the Chinese company is one of the biggest sellers in its home market. Its latest offering is the K900 - a 5.5" smartphone - slightly larger than the three we detailed yesterday but with the same 1920 x 1080 pixel count to give a resolution of 400ppi. It also features a 13MP Sony Exmor RS (stacked CMOS) sensor behind a 22.4mm equivalent F1.8 lens. Click here to find out more.

CES 2013: High-resolution screen advances were on display at the Consumer Electronics Show in Las Vegas this week, with everyone from tablet makers to television manufacturers pushing pixel count further than ever before. Sharp stole the show, in terms of screen resolution technology by exhibiting a 85-inch 8K LCD screen prototype. Co-developed with Japanese broadcaster NHK, the UHDTV screen offers 16 times the resolution of a standard 1080 TV and would allow you to display a 33MP image without downscaling or cropping. 

CES provided a chance for us to get our hands on two of the latest smartphones. Interestingly, Sony's Xperia Z, ZTE's Grand S and the Huawei Ascend D2 are all built around 5", 1920 x 1080 pixel screens and feature 13MP cameras. All run Android 4.1 (Jelly Bean) and yet, despite the spec similarities, there are still differences - in the user experience as well as the processors used. We had the opportunity to use all these phones, to see how they behave - find out what we thought.

CES 2013: We got a chance to get our hands on a near-to-production example of Fujifilm's X100S, to fill-in the details we couldn't cover in our preview. The button layout of the camera is now finalized and the camera's focus and manual focus systems are fully working (and rather impressive), so read our hands-on article to find out how big a difference that little 'S' makes.

The Fujifilm X100S is the latest in a recent rush of cameras to include phase-detection elements on its imaging sensor, giving an AF system that is a hybrid of contrast and phase-detection methods. However, Fujifilm also uses this system to provide a unique and incredibly clever manual focus aid - which could finally allow digital cameras to offer the speed and convenience enjoyed by manual-focus SLR and rangefinder users. Fujifilm UK has posted a video showing 'Digital Split Image' focusing and Japanese camera site DCWatch has published details that allow us to show how it works.

Canon has announced two additions to its range of Cinema EOS prime lenses, a 14mm T3.1 and 135mm T2.2. The CN-E14mm T3.1 L F and CN-E135mm T2.2 L F are both designed to be used on movie cameras with image sensors up to 35mm full frame in size, and include a range of features optimized for movie shooting. These include geared focus and aperture rings with markings designed to be read from the side of the camera, 11-bladed circular aperture diaphragms, and all-metal weather-resistant construction. The 14mm T3.1 will be available from April 2013 at an estimated retail price of $5,500, while the 135mm T2.2 will appear in May for $5,200.

CES 2013: As promised we've used the CES show as an opportunity to get our hands on the Samsung NX300. The latest model shares its looks with the NX210 but has been substantially re-worked under the skin. We had a chance to play with the NX300 and Samsung's innovative 3D variant of its 45mm F1.8 lens that has been developed alongside it. Click here to see what we found.

CES 2013: Panasonic has been demonstrating a prototype of a 20" tablet at the CES show in Las Vegas. The large 3:2 tablet is built around a 4k, 3840x2560 pixel IPS display, giving a resolution of 230ppi. The tablet runs Windows 8, meaning it can run full PC software such as Adobe Photoshop. The prototype included a 128Gb SSD to allow fast access to images stored on the device. It also includes a standard USB port for connecting a card reader but only has a port for microSD cards built in.

The UK's biggest high-street camera retailer, Jessops, has gone into administration, putting 192 stores and 2,000 jobs at risk. The company's website is not accepting orders and administrator PricewaterhouseCoopers has said vouchers and returns would not be honoured at present. The company, that has been slow to respond to competition from internet retailers, was rescued in 2009 by HSBC, which bought into the company in return for writing off some of its debts. However, increasingly stringent credit terms imposed by suppliers (a common move when there is doubt surrounding the future of a company), and predictions of further falls in camera sales led to the administrators being called.

Just posted: Our hands-on first look at the Fujifilm X100S. Fujifilm's update of its large sensor, fixed lens X100 adds significant upgrades, including a 16MP X-Trans CMOS sensor with on-chip phase detection AF, a higher resolution LCD display in its unique Hybrid optical/electronic viewfinder, and the company's latest user interface. But there's a whole host of smaller improvements too, which promise to iron out many of the X100's particular quirks. In our first look preview, we take a detailed look through what's changed compared to its predecessor.

Just posted: Our hands-on preview of Fujifilm's updated enthusiast zoom compact, the X20. Using the same basic design as X10, including its fast 28-112mm equivalent F2-2.8 zoom lens, the X20 uses a completely new sensor, a 2/3"-type version of the X-Trans CMOS design used in the company's X-system cameras, but with added on-chip phase detection AF. It also gains an 'Advanced Optical Viewfinder' that's capable of displaying overlaid exposure information, and a couple of design tweaks to take better advantage of this. In our preview we take a closer look at what the X20 has to offer the enthusiast photographer.   

CES 2013: Sakar International has formally announced the distinctly Nikon-esque iM1836 - a modular camera system wearing Polaroid branding. Details are scarce - with the company able to give little information (and some of that being improbable), but the first model is said to be an Android-based, Wi-Fi-connected camera with Ricoh GXR-style interchangeable modules with the sensor built into the lens. Further adapter modules are promised to allow use of Pentax K, Nikon F and Micro Four Thirds lenses.

CES 2013: Sigma has announced the DP3 Merrill, the latest iteration of the company's enthusiast large sensor compact camera. Nearly identical to the earlier DP Merrill models, this camera features the familiar 15x3MP APS-C Foveon X3 sensor, but it is now mated with a 50mm (75mm equiv.) F2.8 lens. The lens lends itself to portraiture and, with a minimum focus distance of 22.6cm, offers respectable 1:3 magnification. Video recording is still limited to VGA resolution but the DP3M can shoot at up to 4 frames per second for 7 frames in Raw.

CES 2013: Sigma has published details of what it will be showing at the CES show, including pricing details for two of the lenses it announced at Photokina 2012. The 17-70mm F2.8-4 DC Macro OS HSM, part of the company's 'Contemporary' line of lenses, will retail for around $499. Meanwhile the 120-300mm F2.8 DG OS HSM, which falls into the company's 'Sports' category, will sell for around $3,599. The company has also given details of a monochrome processing mode that it's added to its Sigma Photo Pro processing software for its Foveon-sensored cameras.

CES 2013: Olympus has announced the Stylus Tough TG-2 iHS, the latest flagship of its Tough series of waterproof compact cameras. This update to the TG-1 model is now waterproof down to 15m (50 feet), has a 12MP CMOS sensor and a 4x optical zoom lens with a maximum aperture starting at F2.0. Further rounding out the specifications are a 3.0" OLED rear display, built-in GPS and elevation recording and 1920 x 1080 video output. The TG-2 iHS will be available in March in both red and black versions for US $379.99.

CES 2013: Olympus has announced the Stylus SH-50 iHS, which the company claims is the first compact camera to feature E-M5-style 5-axis image stabilization. The 16MP camera also features a 24x 25-600mm (equiv.) optical zoom lens, 1080i60 video output and a touch-sensitive 3-inch rear LCD. Taking design cues from the company's higher-end PEN cameras, the SH-50 iHS sports a textured hand grip and will be available in March in both black and white versions.

CES 2013: Olympus has announced the TG-830 iHS and TG-630 iHS, two new additions to the company's TOUGH series of travel-friendly waterproof compact cameras. The mid-range TG-830 iHS is waterproof to 10m (33 feet) and has a 5x optical zoom lens to go along with its 16MP back-side illuminated CMOS sensor. Video can be recorded in 1920 x 1080 resolution, with the option to capture high speed clips at 120 fps in 720 resolution mode, for slow motion playback. The entry-level TG-630 iHS is waterproof down to 5m (16 feet). Both models will be available in March in a range of colors.

CES 2013: Olympus has announced the Stylus SZ-16 iHS and the Stylus SZ-15 iHS - a pair of 24x compact superzoom cameras. Both cameras offer an 25-600mm equivalent zoom range. The SZ-16 iHS is based around a 16MP CMOS sensor, allowing it to offer 1080p video and the other high-speed features needed to wear the company's iHS branding. The SZ-15 makes do with a 16MP CCD sensor, restricting it to 720p video capture. The SZ-16 iHS uses Olympus' previous-generation TruePic V processor, while the SZ-15 uses an older TruePic III+ chip.

CES 2013: Nikon USA has announced it is releasing the D5200 launched elsewhere in November 2012. The 24MP upper entry-level DSLR gains the 39-point AF system from the company's higher-end models. The camera will cost around $899.95 with the Nikkor 18-55mm F3.5-5.6 VR kit lens. It includes an articulated 920k dot LCD and is compatible with the clip-on WU-1a Wi-Fi module. We previewed it back when it was launched in Europe so, if you still don't know what makes the D5200 tick, the preview should cover it.

CES 2013: Nikon has launched two additional camera and two lenses to the Nikon 1 mirrorless system. The 10MP 1 S1 and 14MP 1 J3 are two small mirrorless camera both featuring hybrid-AF. The 1 J3 looks a lot like the previous 1 Js but sees the mode dial moved to the camera's top plate. The S1, meanwhile is a smaller, less expensive model aimed squarely at point-and-shoot users. In addition Nikon has announced the 1 Nikkor 6.7-13mm F3.5-5.6 VR 18-35mm equivalent wide-angle zoom and a retractable superzoom lens, the 1 Nikkor 10-100mm F4-5.6 VR.

CES 2013: Nikon US has announced a radio-frequency camera triggering system compatible with all its current DSLRs. The WR-10 system works over a 60m range and, unlike the current infrared system, does not require a line-of-sight between the trigger and the camera. Users of mass-market Nikons (D600 and below) can use the WR-T10 transmitter to focus or fire cameras with WR-R10 receivers attached to them. Owners of pro-grade DSLRs with 10-pin connectors can use the WR-A10 adapter to connect the R10 to their camera. This combination allows the camera to act as a host that can remotely trigger up to 64 other cameras.

CES 2013: Nikon has announced the Wi-Fi-enabled Coolpix S6500 compact camera. It includes the latest 'Glamour Retouch' effects including 'Reduce Dark Circles' and 'Redden Cheeks'. The camera is built around a 16MP BSI-CMOS sensor, 12x 25-300mm (equiv.) optical zoom lens and offers Full HD video recording capabilities. It will available late January for a suggested retail price of $219.95 in silver, black, red, and orange.

CES 2013: Sony has announced five Cyber-Shot compacts, including the Wi-Fi-capable, 16MP CMOS-based DSC-WX80 with its 25-200mm equivalent zoom lens. There are also two CCD-based W-series cameras - the DSC-W730 which shares its lens with the WX80, and the DSC-W710 that has a 5x 28-140mm equiv. zoom. Beyond these are the 16MP CCD-based 5x rugged, waterproof DSC-TF1 and the 26x DSC-H200 superzoom.

Just Posted: Our hands-on preview of the Pentax MX-1. The enthusiast sector has become so vibrant that our pre-Christmas roundup included nine cameras. Not wanting to be left out of the action, Pentax-Ricoh has launched its own 12MP camera with a 1/1.7" sensor - the MX-1. As well as a slightly familiar-looking 28-112mm equivalent, F1.8-2.5 zoom lens, the MX-1 takes the unusual step of including brass top- and base-plates - meaning its classic looks should become even more pronounced as it ages. Read on to find out more.

CES 2013: Canon's PowerShot N, with its 'either way up' design and Creative Shot processing filters, is one of the most unusual cameras we've seen for some time. Canon's talking about it as a companion to a smartphone, and to this end it includes Wi-Fi connectivity and the ability to upload photos and videos to social media. We've had the chance to handle one briefly, and have prepared a quick first impressions article to give an idea of how it works.

CES 2013: Samsung has announced six Wi-Fi capable compact cameras, including compact superzooms and its latest Dual-View model. The WB250F is an 18x, 24-432mm equiv compact superzoom with a 3.0" touch screen and the company's latest Wi-Fi implementation - dubbed 'Smart 2.0.' The WB250F uses a 14MP BSI CMOS sensor while its near-twin, the WB200F, uses a 14MP CCD chip. Meanwhile the WB800F uses a 16MP BSI CMOS sensor behind a 21x, 23-483mm equivalent lens. The WB30F uses a 16MP CCD with 24-240mm equivalent lens. The latest DualView model shares the same sensor and a 25-125mm equiv zoom and includes a 1.5" front LCD. The ST150F is a budget style compact - taking most of the DV150F's features but without the front screen and costing $20 less.

CES 2013: Fujifilm has announced the X100S - a significantly enhanced replacement for its X100 large sensor, fixed-lens compact camera. The X100S retains its predecessor's classic styling but has been extensively re-worked inside, with a 16MP X-Trans sensor that includes on-chip phase-detection elements (a technology first utilized by Fujifilm), and a higher-resolution LCD in its Hybrid optical/electronic viewfinder. A faster 'EXR II' processor, along with the on-chip AF information help Fujifilm offer what it says is the world's fastest AF. The X100S backs-up its rangefinder-esque looks with a digital split-image manual focus system, allowing fast manual focusing. A great many fine details of the camera have also been enhanced - we look in greater detail in our hands-on preview article.

CES 2013: Fujifilm has announced the X20 - a substantially upgraded re-working of its high-end enthusiast compact. The biggest changes over the X10 are the adoption of the X-Trans color filter pattern from the company's mirrorless cameras, along with an LCD added to the optical viewfinder to allow shooting information to be overlaid. A faster processor and on-chip phase detection elements promise fast focusing while the addition of a 'Q' quick-menu button should also improve the camera's usability.

CES 2013: Fujifilm has announced the 16MP FinePix HS50EXR, its new flagship superzoom camera. The HS50 features a 42x 24-1000mm (equiv.) optical zoom lens and a new EXR CMOS II sensor. A 3" articulated rear LCD complements the camera's built-in 920k dot electronic viewfinder. The HS50 records 1080p60 video alongside stereo audio. An 'Intelligent' hybrid autofocus system allows for automatic switching between contrast and phase-detection AF operation. Burst modes as high as 11 fps are possible in full resolution mode. A more affordable HS35EXR has also been announced, which features an earlier version sensor, 30x optical zoom and 1080p30 video recording.

CES 2013: Fujifilm has announced the FinePix SL1000, a 50x superzoom camera. The 16MP SL1000 features a 24-1200mm (equiv.) optical zoom lens and a newly developed image stabilization system.
