Buying a new lens can be one of the most difficult choices you make as a photographer. How do you know which lenses are a good buy if you can’t try them out beforehand? Why do some Canon lenses cost so much and others so little? Should you buy a zoom lens or a prime? Is that superzoom a good a deal as it seems?

There are so many questions that it’s easy to get confused. That’s why I wrote Understanding Lenses: Part I – A guide to Canon wide-angle & kit lenses. Roughly half the eBook is dedicated to exploring Canon’s range of wide-angle and kit lenses. This section explains the differences between Canon’s lenses and gives you the information you require to decide which lens (or lenses) to buy.

The other half is dedicated to helping you get the best out of your kit and wide-angle lenses. Photography is a creative endeavour, and lenses are the ‘eyes’ of your camera system. Once you understand how lenses ‘see’ you can harness their creative potential to create eye-catching and dramatic images.
