As a reviewer, there is no greater thrill than being privy to a product that you know will either revolutionise or turn the world upside down. The first Palm Pilot, USB devices, and the Canon 1Ds.

If you had asked me a few weeks ago what the advantages of eight megapixels (MP) were over five, I would have said very few. However, that was before I discovered the fun factor in being able to play with an image that is up to 115cm by just over 86cm (72dpi).

Once upon a time not too long ago, your average inkjet printer had a single tricolour ink cartridge. Of course, the print quality was fairly ordinary, but it did the job. Today, with digital cameras the norm and home users wanting to print their own photographs, your photo printer may have as many as eight different ink cartridges.

If you can afford one and can find one, don’t think twice about it. If not, rent one from a specialist outlet for phenomenal results

A true pro camera that slots in nicely between the flagship Canons

Forget gold plated and diamond encrusted – if you've got three grand to spare and don't mind weighty snappers, this is the camera to blow it on

Amazing images and great fun, but this quirky cam is way too pricey for most

We find this model hovering in the no-man's-land between desktop replacement and notebook. Its large form factor and huge screen come at the expense of weight, while the wireless and large battery do make it viable for users on the move.
