Sigma 17-70mm f/2.8-4.5 DC Macro - unknown Mount

The Sigma 17-70mm f/2.8-4.5 DC Macro is a standard zoom lens designed specifically for APS-C digital SLR cameras. It offers a slightly wider and longer reach than typical kit lenses, paired with a faster maximum aperture at the wide end. The 'Macro' designation refers to its close-focusing capability, allowing for a minimum focusing distance of approximately 20cm across the zoom range. On the used market, the zoom ring should be tested for consistent resistance, as some copies can develop loose rubber grips over time. SDS inspects the autofocus motor for noise and speed, and we carefully check the front element for scratches, as the lens often requires the use of a hood to protect its large forward glass. Internal dust is common in these external-zooming designs but rarely affects image quality.
