The Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM Contemporary lens is a versatile all-in-one zoom designed for APS-C-format Sigma SA-mount cameras, providing a 27-450mm equivalent focal length range.

The lens features a Hyper Sonic Motor for fast and precise autofocus with full-time manual focus override, an Optical Stabilizer to reduce camera shake during handheld shooting, and a 1:3 maximum magnification with a 1.3-foot minimum focusing distance for close-up work.

Built with a Thermally Stable Composite material and brass bayonet for durability and precision, this lens includes a rounded seven-blade diaphragm for smooth bokeh quality and a zoom lock switch to prevent accidental adjustment. Compatible with the optional Sigma USB Dock for lens optimization and firmware updates, this compact and lightweight Contemporary-series lens balances versatility and performance for everyday and travel photography applications.
