SUMMARY
The Sigma 20-60mm f/2.8-4 DG lens for full-frame cameras starts at a wider 20mm instead of the usual 24mm, weighing under a pound. This wider perspective benefits landscapes, interiors, and vlogging, though it sacrifices reach by topping out at 60mm. Image quality is strong at 20mm, with usable corner sharpness, and close-up performance is a notable strength. While distortion and vignetting are significant, in-camera corrections mitigate this, making it a compelling option for travel and video shooters who prioritize width over telephoto reach.
