Just posted! Our in-depth review of the Pentax K-x. Despite its compact size and inconspicuous exterior the K-x boasts an impressive feature set that is, in parts, not that far off the semi-pro K-7. In the entry-level segment of the market the new model will be facing fierce competition from the likes of Canon's EOS 500D and the Nikon D5000. Can the Pentax K-x make its mark amongst such well established rivals? Click through to find out. (17:55 GMT)

Just posted! Our in-depth review of the Leica X1. Back in September Leica surprised everyone with the announcement of its entirely home-grown large-sensor compact, which combines a fixed 35mm-equivalent lens with an APS-C sensor. Featuring a pared-down design with traditional analogue-style control dials on its top plate for shutter speed and aperture, the X1 certainly looks desirable on paper, but at an asking price around $2000, can it live up to the inevitable high expectations? We've had our hands on a production X1 for the past couple of months - click through to find out what we thought of it. (11:05 GMT)

Just posted! Our review of the Canon PowerShot G11. The G11 is the company's flagship compact camera, offering a flexible zoom range, solid build and classic styling. This latest incarnation of the G-series regains the much lamented flip-out screen lost from its recent predecessors, it also uses a 'high sensitivity' CCD that could put right the G10's disappointing low-light performance. So, after extensive testing, how did the G11 fare? (11:05 GMT)

Just posted! Our in-depth review of the Nikon D3000, which replaces the popular D60 as Nikon's latest entry-level DSLR. A new guide mode and revamped AF system make the D3000 a compelling upgrade for D60 and D40X users, but the lack of a Live View function will not go unnoticed in the feature-hungry entry-level sector. Does the D3000 have what it takes to become king of the beginners' DSLRs? Click to read our in-depth 27 page review. (13:55 GMT)

Olympus UK has been doing something we found quite interesting. How do you promote a new class of camera to a mainstream audience without confusing them with talk of mirrors and sensor sizes? Its solution appears to be to not talk about cameras at all - instead it's got Kevin Spacey to talk about pictures and memories. (10:55 GMT)

Nikon has launched a new 300mm F2.8 VR lens featuring the company's latest image stabilization system. The AF-S Nikkor 300mm f/2.8 ED VR II is designed to be small and light enough to hand-hold while the company says the VR II system can offer 'four or more' stops of compensation for lens shake. It also includes nano-crystal coating and is dust and moisture sealed. Recommended retail prices will be $ 5899 / €6050 / £5099.99. (08:55 GMT)

Nikon has released a new 2x AF-S teleconverter, the world's first to include an aspherical lens element. The AF-S Teleconverter TC-20E III is a completely new optical design designed to minimise its impact on image quality. When used with the 300mm F2.8 VR II lens launched today it would offer an effective 600mm reach at up to F5.6. (09:05 GMT)

Olympus is offering European customers a free FL-14 flashgun if you buy one of its E-P1 mirrorless interchangeable lens cameras before the end of January 2010. The offer is valid for both body-only and kit purchases and starts on December 12th in the UK and 15th in mainland Europe. We've added this offer to our list of holiday season promotions.

Pentax has launched a weather resistant 100mm F2.8 Macro lens. The lens, which is designed to work with both digital and film SLRs, features weather-resistant construction to match the company's environmentally-sealed K-7 mid-level DSLR. It also features an aluminium body in the style of the company's 'Limited' prime lenses and offers full-time manual focus override. (22:00 GMT)

Just posted! Our in-depth review of Sony's mid-range SLR, the Alpha DSLR-A550. The A550 is part of a new range that sits between the A200/A300 and the high end A700, and offers an interesting combination of features (including in-camera automatic HDR, 7 fps continuous shooting and Sony's excellent live view system) whilst retaining the Alpha line's emphasis on friendly ease of use. Find out how we got on with the Alpha 550 after the link... (15:15 GMT)
