We've just posted our Panasonic Lumix DMC-G6 preview, covering Panasonic's newest Micro Four Thirds mirrorless interchangeable lens camera. The G6 comes barely a year after the G5, and offers several updates, including a 1.44 million-dot OLED electronic viewfinder and the same sensor as the GH2. Its body has also been restyled and the touch-sensitive technology of its fully-articulated screen has been upgraded. Like its little brother the GF6, the G6 also includes built-in Wi-Fi connectivity with Near Field Communication (NFC). Click through for our hands-on preview.

Sony has announced the Cyber-shot DSC-HX50V, a 30x compact superzoom camera that includes both Wi-Fi and GPS. It's built around a 20.4MP 1/2.3" BSI CMOS sensor, sitting behind a 24-720mm F3.5-6.3 lens. It includes 3-axis SuperSteady Shot image stabilization and can shoot at up to 10 frames per second for 10 frames. Its battery is rated at around 400 shots-per-charge and the Wi-Fi can be used for both file transfer and remote control. It will be available from May at a recommended price of $450.

Panasonic has announced the Lumix DMC-LF1, the first in a new line of Raw-shooting enthusiast compacts. The LF1 marries the sensor from the LX7 to a longer, slower lens and adds an electronic viewfinder. The camera combines a 12MP 1/1.7" CMOS sensor with a 28-200mm equivalent F2.0-5.9 lens and finds room for a 202k dot-equivalent electronic viewfinder. It becomes the fifth Panasonic model to offer Wi-Fi for remote control and wireless communication that can be set up using NFC.

Panasonic has announced the Lumix DMC-G6 - the latest in its mass market series of DSLR-styled mirrorless cameras. The G6 gains considerably improved movie capabilities, including full exposure control, an external mic socket and the sensor from the GH2. It also adds the NFC-aided Wi-Fi for simple remote control and image download that we first saw in the GF6.

Panasonic has created the Lumix G Vario 14-140mm F3.5-5.6 ASPH Power OIS, a second-generation 10x zoom for Micro Four Thirds cameras. The lens offers a smaller, lighter, less-expensive alternative to the original G Vario HD 14-140mm F4.0-5.8 ASPH Mega OIS. The latest version features three aspheric and two ED elements and an internal focus design with linear stepper motors to make the most of the faster focus processing of the latest Micro Four Thirds bodies.

We've just posted a 6-page review of the Canon Pro-10 printer.

Furthermore we've shot the GR next to the Coolpix A in a real-world setting. Click here for all this and more.

Just posted: Our hands-on preview of the Sigma 18-35mm F1.8 DC HSM Art lens. The announcement of the world's first constant F1.8 zoom caused a lot of discussion, much of it centered around the idea that the brighter aperture would help APS-C DSLRs to compete toe-to-toe with full frame cameras in many respects. We've had a chance to handle the lens and prepare a preview putting its capabilities in more context. Click here to find out more.

Korean website lcap.tistory.com has published what it claims are sample images from the new Sigma 18-35mm f/1.8 DC HSM lens, purporting to show its performance in a range of different shooting situations, on both a Canon EOS 600D and 5D Mark III.

The lens covers a 27-52.5mm equivalent range, and will be available in Canon, Nikon and Sigma mounts. As yet there is no announcement of a recommended price. The lens will offer the depth-of-field equivalent of a constant F2.7 on full-frame, and allow the use of lower ISO settings in low light, which may under-cut the need for some photographers to change formats.

Dutch designer Ruben van der Vleuten was curious to know how many people and steps were involved between mailing and receiving a parcel, so he decided to find out. He installed a tiny 3MP camera in a parcel, built a timer circuit using Arduino (a simple single-board microcontroller designed to control devices) and shipped it to himself. The timer of the circuit was set to make a 3 second video every minute and make longer videos while the box was moving. Click through to watch the results.

Sensor maker Aptina has announced a 14MP 1"-type sensor for use in mirrorless and video cameras. The AR1411HS enters the range alongside the existing 10MP model and offers even faster shooting capabilities. The 14MP chip can shoot full-resolution images at up to 80 fps and can shoot either 4K or Quad HD (allowing high quality 4:2:2 color) at up to 60 fps. The company suggests the 1" format (actually 13.2 x 8.8mm) offers an effective balance of image quality, price and capabilities to make a sensible middle ground between the tiny 1/2.3" sensors in most compacts and the APS-C sensors used in many mirrorless models and DSLRs. 

Just posted: Our hands-on preview of the Ricoh GR. The GR is the spiritual successor to the GR Digital series and features a 16MP APS-C sensor behind its 28mm equivalent, F2.8 lens. It's the first product to show signs of post-merger integration at Pentax-Ricoh, gaining the Pentax TAv exposure mode but retaining a host of traditional Ricoh features. We've been shooting with a production GR alongside the Nikon Coolpix A, click to find out more.

Just posted: Our hands-on preview of Fujifilm's latest telephoto zoom lens, the Fujinon 55-200mm F3.5-4.8 R LM OIS.

It also includes optical image stabilisation and two linear stepper motors for quiet focusing. Click through to read our detailed preview for more information. 

Pentax-Ricoh has announced the much rumored and leaked Ricoh GR, a 16.2MP APS-C sensor enthusiast compact camera. The GR continues on from Ricoh's GR Digital series of high-end, fixed-lens models, gaining a much larger sensor but continuing to offer a 28mm equivalent field of view, now with an F2.8 maximum aperture. It also retains the GRD IV's high-res 1.2m dot LCD and a range of photographer friendly functions. Despite a sensor nearly nine times as big, the recommend price increase by just $200 over the GRD IV, to $799.

Fujifilm has officially announced the Fujinon XF 55-200mm F3.5-F4.8 R LM OIS telephoto zoom for its X system of mirrorless cameras. Headline features include optical image stabilisation with a claimed 4.5 stops benefit, dual linear stepper motors for focusing, all-metal barrel construction, and premium optics. The lens also features an aperture ring like that on the company's XF 18-55mm zoom. Fujifilm has also updated its roadmap of upcoming lenses to include the XF 56mm F1.2 R, which is scheduled for release in January 2014. Finally the company is promising firmware updates to improve the autofocus speed of both the X-Pro1 and X-E1, which will be available to download in July.

Continuing the move toward cameras without optical low-pass filters, Pentax last year released two versions of its flagship digital SLR, the K-5 II and K-5 II S, the latter with no OLPF. Both cameras retain the same body and 16MP resolution, but get an upgraded autofocus sensor and a new air-gapless LCD. We've started our review, but wanted to put up a quick look exploring whether there's a difference between the two in terms of image quality. 

Andy Rubin, co-founder of Android, claims that the popular mobile operating system was originally designed for digital cameras, not phones. In an interview published by PC World, Rubin said that the original concept, as pitched to investors back in 2004, was for 'a camera platform with a cloud portion for storing images online'. By the time Google acquired Android in 2005, however, the plan had changed and Android was developed for mobile handsets. Click through for more details and a link to the full story at PCWorld.com.

Street photography isn't everyone's cup of tea, and for every Cartier Bresson, watching from a distance, there's a Weegee, pushing a camera into the faces of their bemused subjects without asking permission. Los Angeles-based photographer Johnny Tergo has taken this approach to a new level, rigging up his truck with a camera and bright studio strobes in order to 'bring the studio lighting aspect to everyday real life on the streets'. Click through for the full story, and images (via wired.com)

Citizen Finetech Miyota has developed an LCD panel for electronic viewfinders of digital cameras its claiming is the highest resolution available. It offers a 1280x960 pixel display (equivalent to 3.69 million dots). This exceeds the 2.36m dot (1024 x 768 pixel) resolution of the current Sony OLED and Epson LCD units. It uses a field-sequential design, showing red, green and blue information in sequence rather than being able to show them all at the same time, but the panels 120Hz design should avoid color breakup (tearing) the company says. The panel will enter mass produced in summer 2013.

Just posted: Our Canon EOS 100D (Rebel SL1) preview samples gallery. We've been lucky enough to get our hands on a pre-production sample of Canon's latest miniaturised SLR, and have assembled a quick samples gallery to give an idea of how it performs. We've shot using the EF-S 18-135mm f/3.5-5.6 IS STM and EF 40mm f/2.8 STM pancake lenses, and aimed to cover a variety of subjects and lighting conditions. The pre-production camera used offers 'Beta' standard image quality, so may not fully reflect the final image quality (although it's unlikely to be radically different).   

Online user experience company Teehan + Lax has created a free tool for creating 'hyperlapse' videos using Google Street View.
