In this comparison review, we’re looking at the three most prominent cameras – the Sony Alpha A100, the Canon Rebel XTi and the Nikon D80. The Canon and the Sony are both available online for under $900 with a lens and both offer dust removal and reduction features. The Sony has in-camera image stabilization – Super Steady Shot technology that moves the sensor in response to camera shake. The Nikon lacks dust technology and stabilization, but goes for about $1100 with a similar lens (it’s under $1000 for the body alone). Is there a separate niche for each of these, or is one simply a better buy?

So once again it’s a case of evolution with the new PowerShots delivering higher resolutions, faster ISOs and bigger screens than their predecessors. The previous models may have been ideal for beginners wanting to grow or enthusiasts wishing to compliment a DSLR, but the big question as always is whether the increased resolution really offers any benefit or worse, comes at the cost of compromised noise levels? We’ll reveal all in our full review of the Canon PowerShot A640 and compare it against key rivals…

Take one of Canon’s most popular lenses, the Canon 70-200mm f/4 L, add an up-to-4-stop Image Stabilizer and you get the Canon EF 70-200mm f/4.0 L IS USM Lens. If you don’t need the subject-action-stopping and background-blurring capabilities of the faster Canon EF 70-200 f/2.8 L IS Lens, this lens will deliver everything else you need in a smaller, lighter and less-expensive package…

Overall I was very impressed with the Canon G7. It does a lot of things right within the context of its price, size and its likely intended constituency. Unfortunately a consequence of being a JPG-only camera is that too many technical decisions need to be made prior to shooting. Things like colour balance, saturation, sharpening, etc all get baked into the file, and the ability to recover burned-out highlights (which raw files provide) is lost when all you have is a JPG…

Canon has announced new firmware for the EOS 30D. Version 1.0.5 fixes a bug which mis-reports the number of continuous shots which can be taken and also adds a ‘semi-gloss paper’ option for direct printing. This firmware can be installed by simply copying the update file to the Compact Flash card and is available as a self-extracting archive for Windows or Macintosh.

The Canon Powershot A710 IS is a 7 megapixel compact digital camera with a 2.5 inch LCD screen and optical viewfinder. For the first time ever on a Canon A-Series compact, the A710 features image stabilizer technology to help combat camera-shake. Canon have also extended the optical zoom lens to 6x, giving an effective focal length of 35-210mm. Under the surface, the Canon Powershot A710 IS uses the same advanced DIGIC II processor as the company’s digital SLR cameras for fast performance and image processing…
