*ist DS + Sigma 30mm F1.4 gallery
Recently I have found an interesting page at pbase.com. This is San Diego Fashion & Lifestyle Show photo report by Derek Leung. The photos are spectacular, and even though they are all made with Pentax *istDS and Sigma 30mm F/1.4 EX DC large aperture prime lens. This little (but pretty expensive) Sigma is a nice walk-around normal (46mm in full-frame terms) prime and it gives amazingly shallow DOF. Look at the pictures here and here - the DOF and “bokeh” are very good.
