Panasonic has introduced the DMW-TA1 tripod adaptor for its Lumix DMC-GF1 Micro Four Thirds camera. The design of the adaptor makes it easier to use tripods when large-diameter lenses such as Lumix G Vario 45-200mm or the HD 14-140mm are attached to the camera. (11:00 GMT)

Just added: Our gallery of images from a pre-production Leica S2. Just recently Leica announced a delay in production of its new S2 autofocus medium format DSLR which will now be available from December. However, we already have our hands on a pre-production model and took it out into the gray London autumn for some snapshots. So here are a selection of images using both the APO-TELE-ELMAR-S 1:3.5/180 and the SUMMARIT-S 1:2.5/70 ASPH lenses. There is a mixture of camera JPEGs and RAW conversions. (13:45 GMT)

Just posted! Our lens review of the Canon EF 100mm F2.8 L IS USM. A few months ago Canon announced a new optical image stabilisation technology, dubbed 'Hybrid IS', that promises greater effectiveness at close distances for which conventional IS systems tend to be ineffective. The first lens to feature this has duly arrived in the shape of Canon's latest 100mm Macro, which alongside image stabilisation has also gained the added attraction of the premium 'L' designation. We take a close look to see if it's worth the premium over the older EF 100mm F2.8 USM Macro, which remains in Canon's range. (09:55 GMT)

Just Added: Our samples galleries of the Ricoh GXR camera system. We've been given a chance to get out and about with both the lens modules the company announced this morning. So here are a selection of Beta samples from both the A12 APS-C 50mm equiv. prime and the S10 1/1.7" 24-72mm zoom modules. We've prepared 52 shots taken at a range of ISOs, apertures and (where appropriate) focal lengths, including a mixture of camera JPEGs and RAW conversions. (10:55 GMT)

After several weeks of rumors Ricoh has unveiled its first digital system camera, the GRX. The system takes a novel approach by offering interchangeable slide mount 'lens units' - sealed modules containing both optics and sensor, meaning it can switch from a large (APS-C) 12 MP CMOS with a fast prime lens to a tiny 10 MP CCD (with a 24-70mm lens). We've had a pre-production GXR system in the office for a week and have produced an in-depth hands-on preview which you'll find after the link. We've also taken lots of pictures with both lens modules so look out a little later today for an extensive gallery of samples. (06:00 GMT)

Pentax Europe has said its forthcoming online store will provide wider access to accessories, rather than cameras as previously reported. The move will allow the company to directly sell a wider range of products to consumers in UK, Germany France, Switzerland and Hungary. A statement from the company corrects an earlier press release from online shopping specialist Digital River about an online store that will be established before the end of the year. Pentax has struggled to achieve widespread distribution of its full product range in some European markets in recent years. (11:30 GMT)
