Just Posted: Our review of the Samsung NX10. It's been just over a year since Samsung announced its NX mirrorless interchangeable lens camera system, the first to feature an APS-C sized sensor as used in the most popular DSLRs. It packs a 14.7MP sensor and 'VGA resolution' LED screen into a small, DSLR-like body that exactly resembles the mockup shown by the company back in March 2009. We've been thoroughly testing it to see whether its combination of high resolution sensor and small body is enough to win over people who would otherwise buy a DSLR or Micro Four Thirds mirrorless camera.

On paper its the most compelling Rebel-series DSLR to date, so can it span the bridge between first-time DSLR buyers and more experienced users? Read our full test to find out.

Sensor developer Rokton has announced that it has developed a circular image sensor. The company add the strapline ‘Circular sensors for your circular lens, why throw away half of the image?,' to an idea often raised on the dpreview forums. It has made the idea a reality by developing a novel fabrication process that uses a clever approach laying down sensors in a honeycomb pattern on the wafer, allowing the production of circular image sensors with a diameter of 43mm – the same as the diagonal of 35mm full frame. These sensors will therefore allow the full image circle of any lens to be used in a mirrorless camera body – with fully flexible in-camera format selection and cropping either during shooting, or after the event. The company says it has developed a prototype with interchangeable lens mounts – allowing you to use virtually every lens ever made for 35mm or smaller formats.
