Many avid photographers will definitely prefer this 35mm lens to the more conventional 50mm. Using a leading-edge design and state-of-the-art production technology, Sigma has honed its performance to the point where it can do full justice to the expressive power of the very latest digital cameras. At low apertures, for example, it can perform like a wide-angle lens, while if it's opened up to F1.4, it will give the background a pleasing bokeh effect and make the subject pop like a mid-range telephoto lens. What makes this lens so desirable is the wide scope it provides for artistic expression.
