Sigma 668101 17-70mm
With a 4-stop Optical Stabilizer and an 8.7-inch close focus across its f/2.8-4 range, this 17-70mm zoom delivers 1:2.7 macro shots and low-light flexibility. The HSM autofocus and viewfinder-visible stabilization keep the 535g build steady for handheld use, aided by anti-shake technology that works independently of camera body stabilization. It’s best for Sony APS-C shooters needing a single, budget-friendly lens for both everyday scenes and detailed close-up photography.
