Here is the Sigma 16mm, 30mm & 56mm F/1.4 Lens Review by David Thorpe. These three reasonably priced Sigma f/1.4 Contemporary lenses compared. See below for both video and comparison table.
At a time when some Micro Four Thirds lenses are costing an arm-and-a-leg to purchase, Sigma seems to be bucking the trend with a collection of f/1.4 Contemporary lenses that are sensibly priced, but at what cost? Do they sacrifice sharpness, focus speed or build quality in exchange for a better price?
