Just Posted: Our review of the Canon PowerShot S100. The S100 is the latest in Canon's range of pocketable photographer's compacts, building on the success of the popular S90 and S95. This most recent model offers a more ambitious 24-120mm equivalent, f2.0-5.9 zoom in front of a Canon-made 12MP 1/1.7" type CMOS sensor, marking a much bigger advance than in the last update. Is it another step towards the perfect pocket shooter or has the camera giant over-reached itself? Find out in our review.

It comes amidst a week of fascinating guest blog posts looking at different aspects of photojournalism.

Fujifilm has been granted a patent for an innovative organic-hybrid sensor technology. However, while interesting, it may not offer a compelling advantage over existing designs, according to sensor technologist Professor Eric Fossum. The company has recently been granted a patent for its work on a sensor that uses an organic (carbon-chemistry-based) material on top of silicon circuitry. Speculation about Fujifilm's forthcoming mirrorless camera has latched onto a technical paper the company published in late 2009, but both Fossum and the company say the work shows more promise for small-scale sensors.

Offices and homes of executives connected to the Olympus accounting scandal have been raided by Japanese police. The move comes after a report commissioned by the company showed that losses of $1.7bn had been concealed for over a decade. However, the company did successfully file its amended accounts by the December 14th deadline imposed by the Japanese stock exchange to avoid being delisted. These restated accounts showed significantly reduced assets, and the company is now rumored to be planning to issue more shares in an attempt to raise money.

Panasonic, Samsung, SanDisk, Sony and Toshiba have announced they are working on a 'security solution' for the Secure Digital format - a move more about transferring paid-for content onto mobile devices than about photography. The system will associate cards with content buyers, so that rights-owners feel they can allow those buyers to move copyrighted Blu-Ray and downloaded HD content onto the cards. Or, in marketing speak: 'enables the effortless consumption of online and offline content across multiple device platforms.'

Wildlife photographer and dpreview.com contributor Uwe Skrzypczak is again making his book 'Wildlife photography: On Safari with Your DSLR: Equipment, Techniques, Workflow' available as a free download. As a goodwill gesture, following the difficulty many people experienced in downloading the book last week, Skrzypczak and his publisher Rockynook will be making the English language version of the book available again from Saturday December 17th for a 24 hour period, this time on dpreview's servers. The German-language version is also available from Skrzypczak's website.

With its 24MP APS-C sensor and high-resolution EVF encased in a compact body with lots of external controls, the NEX-7 is one of the most desirable cameras of the year for the enthusiast photographer - on paper at least.
