A kit bag essential. The classic 35mm is the perfect portrait lens as well as being ideal for a whole range of other disciplines, and here's why. Sigma's 35mm f2 DG DN I C Lens is compact and lightweight, making it super-portable for any kit bag and its all-metal design that's reminiscent of Sigma's Cine lens lineup, gives it a professional and well-thought-through feel. The lens construction and optical design produces exceptional image quality and this is coupled with a wide, bright and fast maximum F2 aperture. This aperture not only helps with low-light shooting conditions but also enables precise depth-of-field control. In addition, the aperture will also capture attractive, circular bokeh in out-of-focus areas.
