Sony has announced the development of the finest-yet pixel-pitch 1/2.5" sensor. The 12.2MP CMOS sensor has been developed for mobile phone cameras, but is of a size commonly used in compact and super zoom cameras. The IMX060PQ sensor, which Sony brands 'Exmor' in common with its DSLR CMOS sensors, will also be available incorporated into an F2.8 28mm-equiv lens unit with piezoelectric driven autofocus - relatively advanced for a camera phone module.

Just posted! Our new lens review featuring the Pentax smc P-FA 50mm 1:1.4. This is the latest in our on-going series scrutinising the optical credentials of the camera manufacturers' various "fast fifties", and looks at a lens which has been around since the days of 35mm film. Designed as a fast 'standard' prime, it's now being pressed into service as a short portrait telephoto on the APS-C sensor. So how well has it adapted to this new role? (16:25 GMT)

Camera and lens maker Sigma has bought Foveon, the sensor technology company that develops the sensors it uses. Foveon's technology uses three photosensitive layers to detect red, green and blue light at each pixel.

Samsung Techwin, the Korean manufacturer, plans to separate out its camera division into an individual entity (under the same ownership), according to news agency Reuters. Samsung Techwin is part of the Samsung Group's machinery and heavy industry division and makes mobile artillery and gas turbines, as well as digital cameras. Tentatively named Samsung Digital Imaging, the new company will have a separate listing from Feb. 1, 2009, allowing its management to concentrate on the fast-moving consumer market into which its products are sold, without also having to also consider sales of aircraft engines.

Dragged kicking and screaming into 2008 we've finally decided to break the code of silence which hovered over the inner workings of the dpreview beast and launch our very own blog, or blogs to be more precise. As of today we now have a more informal channel for our editorial and developer teams to communicate directly with our readership, answer some of your burning questions and give you a peek through the window into the hive of activity which occurs in our basement. It's early days but we've already got a few entries, more to come! (14:40 GMT)

We've had a quick chance to have a look at the new Olympus E-30, so have put together a brief hands-on report. This mid-level DSLR offers many features of the more expensive E-3, with a host of new functions pulled together in slightly smaller format. So what does the E-30 offer to entice the semi-professional shooter into the Four Thirds fold? (05:00 GMT)

Olympus has today announced the E-30 digital SLR. The mid-range DSLR features a 12MP Live MOS sensor and 2.7" tilt and swivel LCD. It also incorportates Live View with Contrast AF, Image Stabilization, 5fps continuous shooting and shutter speeds of up to 1/8000th sec. The E-30 also introduces a set of six 'Art Filters', a Multiple Exposure mode and offers a choice of 9 aspect ratios. (05:00 GMT)

Alongside the E-30, Olympus has released the Zuiko Digital 14-54mm 1:2.8-3.5 II lens; successor to the Zuiko Digital 14-54mm 1:2.8-3.5. The new lens has been redesigned to offer compatibility with the 'High-speed imager AF' system included in recent Four Thirds DSLRs. The lens is a 3x zoom, equivalent to 28-108mm on 35mm format.

Just posted! The Panasonic Lumix DMC-LX3 is that most unusual thing, a compact digital camera that has really caught the imagination of photographers. Moving away from the quirky 16:9 sensor of its predecessors, (the LX1 and LX2), this latest offering matches a bright 24-60mm equivalent zoom to a conventionally-proportioned 11 megapixel sensor. Just to keep things interesting, the sensor is then cropped in three different ways to provide a consistent diagonal angle-of-view in three different aspect ratios. So what did we make of the LX3, competitor or curio? (17:00 GMT)

Just Posted! Canon EOS 50D in-depth review. Canon's EOS 50D is essentially a 40D body with a newly-developed 15 megapixel sensor, a 3.0 inch VGA screen and Canon's updated imaging processor, the DIGIC 4. Canon claims the new sensor's design (new manufacturing processes, redesigned photo diodes and micro lenses) means that despite the higher resolution image noise has improved. As you might imagine, we've had a closer look at this. Find out more after the link. Review now updated using the final version of Adobe Camera Raw 4.6. (12:15 GMT)
