TheSigma Zoom Master 35-70mm f/3.5-4.5 AF is a versatile, entry-level zoom lens from the early era of autofocus technology (late 1980s to early 1990s). Compatibility: Nikon Users: If it’s the AF version, it will only autofocus on Nikon DSLRs that have a built-in focus motor (the "screw-drive" system found on D7000-series, D700, D850, etc.).
