It is extremely useful in shooting pit-lane actions of the FIM World Motorcycling Championships. In addition, travel and available light photography are other examples where this zoom lens can be used with its bright, maximum f/2.8 aperture and compactness. Take for example, its 28mm and 35mm wide-angle focal lengths, they provided me with just the right angle-of-views that are not too wide for most situations compared to a 20mm or 24mm. The 50mm focal length is the standard angle-of-view when I wanted a more natural perspective and the 70mm provide a comfortable working distance for shooting portraits or close-ups. << Back to Main . 1 . 2 . 3 . 4 . 5 . 6 .
