We've spent a bit more time with the Canon PowerShot G1 X, and will be publishing a samples gallery from a pre-production camera in the near future. In the meantime, we've taken the chance to expand our preview based on our further experience and some real-world shooting with the camera. This includes observations about its behavior and a chart showing the camera's maximum aperture at key focal lengths. If you have any burning questions about the camera's behavior, write a comment and we'll do our best to answer when we publish our samples gallery (but do please read the updated preview first, to see if the answer's there). [Updated with studio images at all ISO settings - with real world shots coming on Monday]

CES 2012: Light field camera maker Lytro has been demonstrating early versions of potential features during a shooting event at CES. The event gave journalists the chance to use the cameras and try the 'Advanced Light Field Mode' that the company is experimenting with. We went along and have written this report about what it's like to use a Light Field camera.

CES 2012: Fujifilm has confirmed in a discussion with dpreview, more details about its plans for the X-system. It also said a firmware update for the X10 aimed at reducing the 'white-orb' problem is due in early February, if not before. The firmware update, that addresses the hard-edged white discs or orbs generated when highlight regions clip, will reduce but not completely remove the effect. Meanwhile, the company hinted the X-Pro1 will be accompanied by at least one less expensive model.

CES 2012: Lifestyle photo brand Polaroid has been showing an Android-based camera with a 3x zoom on its stand. The company insists the device is a camera or, when pushed, says it can be thought of as a small tablet computer with a camera. This is despite its apparent similarity to a smartphone shown by Taiwanese contract manufacturer Altek late last year. The 16MP Wi-Fi compatible Polaroid camera features a 3x, 6.5-19.5mm lens and 1/2.33" CCD sensor to give a 36-108mm equivalent lens range.

Adobe has announced a special offer allowing CS4 and CS3 users to upgrade to Creative Suite 6, when it is released. Adobe upset many CS4 and CS3 users when it announced that it was changing its upgrade policy so that only owners of the most recent versions would be entitled to discounted upgrade pricing. Although it has not formally gone back on this policy, the offer will provide an upgrade route for CS3 and CS4 users until December 31st 2012. Users of individual packages do not appear to benefit from the offer. Meanwhile, the company has also renamed its 'Carousel' cloud-based image processing, sharing and hosting service 'Revel.' The company says it 'plans to offer additional photography solutions on the platform in the future, so the new branding more broadly encompasses these offerings.'

CES 2012: The Secure Digital Association has announced a standard for wireless communications from SD cards. The standard builds on the work done by Toshiba, which has been showing compliant cards at CES. The standard includes two communications systems, denoted 'W' and 'D.' 'W' cards can communicate with other devices (such as tablets and televisions), in a peer-to-peer fashion, or can upload to 'cloud' services.  The 'D' section of the standard aslo allows connection to home networks. 'W+D' cards that allow both communication types will also be available.

CES 2012: Panasonic is showing mockups of two large-aperture zoom lenses for Micro Four Thirds. The Panasonic stand plays host to mockups of a 12-35mm F2.8 and a 35-100mm F2.8 lens, prominently badged 'Concept' lenses. Next to the models is a lens roadmap confirming the company's intentions to build a 12-35mm (24-70mm equiv) and 35-100 (70-200mm equiv) 'X' grade zooms, but with a note that the maximum apertures are 'to be determined.' The diagram appears to suggest both lenses will arrive later in 2012.

CES 2012: Casio has released the Exilim EX-ZR200, its range-topping compact camera to the US and European markets. The ZR200, announced in Japan in November 2011, features a 12.5x zoom covering a 24-300mm equivalent range, with a maximum aperture range of f/3.0-5.9. It features the company's Premium Auto Pro mode, an extension of its Premium Auto mode. Rather than simply assessing the scene and using the appropriate shooting mode, the Premium Auto Pro mode will also use the multi-shot HDR and low-light shooting modes in an attempt to offer better images in a wider range of shooting situations.

CES 2012: Casio has released the Exilim EX-ZS150, EX-ZS20, EX-ZS12 and EX-ZS6, refreshing its compact camera range. The four cameras are all based around 16MP CCD sensors and feature the company's 'easy Mode' interface, which offers which offers to guide the user to the optimal setters, as well as providing the ability to simply point-and-shoot. The ZS150 includes a stabilized 12.5x, 24-300mm equiv lens, similar to the one in the flagship ZR200 but the CCD chip means it can't offer that camera's high-speed features. The ZS20 has a 6x unstabilized zoom, starting at 26mm equiv, and including the company's Premium Auto mode. The ZS12 and ZS6 lose both these features, instead including 5x, 26mm equiv zooms.

CES 2012: Fujifilm has said it will produce a Black Premium Edition of its X100 large sensor, fixed lens camera in a limited edition of 10,000 cameras. The black X100s will come with matching lens hood, adapter ring, protective filter and leather 'ever-ready' case. Each will come in a presentation case with a numbered certificate encouraging buyers to use the camera. Beyond the color scheme and accessories, it will remain the same as the standard X100. Pricing hasn't been announced.

CES 2012: Fujifilm has said the leaked lens roadmap for the X-mount used in its X-Pro1 is close but not finalized. Fujifilm's Kayce Baker, speaking to dpreview at the CES show in Las Vegas, said the leaked roadmap was 'a close estimate' of its plans but that some decisions, such as how fast the lenses maximum apertures will be, have not yet been made. The official line remains that there will be nine lenses in the next two years. Meanwhile, in an interview with Amateur Photographer magazine, Fujifilm Digital Imaging director Adrian Clarke has said the X-Pro1 will be part of a range of X-mount cameras. [Updated: video walkthrough of X-Pro1 added]

CES 2012: Hands-on shots of the Canon PowerShot G1 X and Nikon D4 mark the start of our CES coverage. The Pepcom Digital Experience event at the start of the huge CES 2012 tarde show provided a chance for us to take an even closer look at two of the most exciting cameras to be announced in 2012 so far: Nikon's professional D4 DSLR and Canon's enthusiast-targeted G1 X large-sensor compact. We'll be publishing our usual stand reports and full show coverage over the coming days, but we thought this would help whet your appetite for the rest of CES 2012.

CES 2012: Corel has announced AfterShot Pro, a Raw processing and workflow tool based on Bibble's technologies. Coming just a week after the announcement that Corel had bought Bibble Labs (though several months after the deal was done), AfterShot Pro provides the kinds of photo management and non-destructive editing that products such as Adobe's Lightroom offer. The software, available for Mac and Linux as well as Windows, will cost $99 or $79 for existing Bibble 5, PaintShop Pro X2, Lightroom or Aperture customers. A free trial is available from Corel's website.

Just Posted: Our preview of the Fujifilm X-Pro1 and Fujifilm's X system lenses. The X-Pro1 is, in many respects, the camera that many people hoped the X100 was foreshadowing: interchangeable lenses and a cutting-edge sensor combined in a classically-styled body and retaining the excellent hybrid optical/electronic viewfinder. We've had a chance to get our hands on the X-Pro 1 and the 18mm F2, 35mm F1.4 and 60mm F2.4 primes that are being launched alongside it, to get to really make sense of the camera, its capabilities and that unusual color-filter array. Click here to read what we think. [Updated with approx price]

Just Posted: Our hands-on preview of the Canon G1 X large sensor zoom compact. Canon is swimming against the tide somewhat with the G1 X - a camera that embraces the large-sensors used by most mirrorless cameras, but foregoing the interchangeable lenses to create a relatively compact all-rounder. The camera combines a 28-112mm equivalent, F2.8-5.8 stabilized zoom with a 14MP sensor just a fraction smaller than those in Canon's DSLRs. Could this be the photographers' compact that we always wanted the G series to be? Read our preview to find out.

Adobe has released a public beta version of its Photoshop Lightroom 4 workflow and image editing software and we've prepared a comprehensive article looking at the changes it brings. Available immediately for free download from Adobe Labs, the beta features a books creation module, increased support for video files, soft proofing capability and a Google Maps-powered geo-tagging module. What do these changes mean for new and existing Lightroom users? Find out in our hands-on preview.

Pre-CES: Sigma has launched the Digital Neo range of lenses for mirrorless interchangeable lens cameras, with the announcement of the 19mm F2.8 and 30mm F2.8 lenses for Micro Four Thirds and Sony NEX. The two relatively compact prime lenses offer 38mm and 60mm equivalent fields of view, respectively, on the Micro Four Thirds system and, 28.5mm and 45mm on the Sony E-mount. At F2.8, neither lens is spectacularly fast, but both systems benefit from the Sigma beginning to make mirrorless-specific lenses. Pricing and availability information has not been announced.

Pre-CES: Olympus has released the VR-340, an affordable 10x compact superzoom. It features a 24-240mm equivalent zoom and stands out from most of today's other Olympus announcements by being based around a 16MP, stabilized CCD sensor. It also offers a very respectable 460k dot LCD despite its recommended selling price of $149.

Pre-CES: Olympus has unveiled the SZ-12, a 24x compact superzoom camera. The camera is based around an image-stabilized 14MP sensor and adds a 25-600mm equivalent zoom lens. Like the other releases it includes the company's Magic Art Filters, but it also features a well-specified 460k dot 3.0" LCD. The SZ-12 will sell for around $199 from March 2012.

Pre-CES: Olympus has announced the SP-620UZ, the latest in its long-running 'ultrazoom' series of cameras.
