Digital cameras have come a long way since the first consumer based models were released back in 1994. They were once thought to be the reserve of specialist tradesman such as photojournalists, but now they can be found in the hands of people the world over.

Many photographers will agree that Canon offer the most comprehensive digital camera system in their EOS SLR range. This includes the digital camera units themselves, and a wide selection of lenses and other accessories. The Canon EOS SLR cameras have been proven in the field, and are favoured by professionals and everyday photographers alike.

Canon undoubtedly has the largest range of compatible lens assemblies, with both a wide selection of official Canon Lenses and the many compatible 3rd party lens offerings such as those from Sigma Imaging. One of the new comers to this extensive lens range is the Sigma EX telephoto zoom lens for Canon DSLR cameras, which has a maximum 1:8.6 zoom utilising a state of the art optical design specifically designed for EOS cameras.

The Sigma EX telephoto zoom lens for Canon has a focal length of 120-300mm, and Sigma has packaged this into a fixed enclosure which does not change shape when focusing or zooming. This makes the lens easy to handle, and provides a maximum aperture of F2.8 at all focal lengths. The lens is also designed with an inbuilt tripod mount which adds balance to your setup, and creates an ergonomically complete package which is a pleasure to work with.
