Perfect for capturing life-sized macro shots of subjects that require you to keep some distance, is the Canon 180mm F3.5 Macro L USM lens. From a macro perspective this lens is useful for flowers, insects and other small wildlife, but the lens can also be used as a standard 180mm telephoto lens with excellent results. At 180mm the f3.5 constant aperture produces a shallow depth of field that really highlights the subject of the photo.
