Lenses are by far the most expensive facet of photography, whether you’ve chosen photography as a hobby or a career. This lecture explains which lenses work best for which types of photography, for example: why wide angle lenses are best for landscape photography and indoor marketing shots, while zoom lenses are better for portrait photographs and other shots that look best with a blurred background. We also take a look at the correct way to change lenses to minimise damage to your camera body.
