Our Thoughts: Construction
I recently had the opportunity to spend two months traveling with, and testing out, Sigma's new 18-35mm F1.8 DC HSM | A lens. The newest lens in Sigma's 'Art' series, the 18-35mm is marketed toward travel, wedding, and event photography.  It is the first lens of it's kind to offer a super fast f1.8 aperture in a wide-angle zoom lens designed for crop-sensor cameras. The first thing I noticed, when I pulled the lens out of the box, was how solid it felt in the hands.  Although the lens is 0.4" narrower in diameter than my AFS Nikkor 28-70mm f/2.8D IF-ED lens, it weighs nearly as much, only 4.4oz less.  In comparison, my AFS DX Nikkor 18-70mm f/3.5-4.5G has a reported weight of 13.8oz and is roughly half the size.
