An all-in-one zoom for APS-C cameras, the 18-300mm f/3.5-6.3 DC MACRO OS HSM Contemporary Lens from Sigma provides users of Canon EF-mount cameras with an extremely versatile focal length equivalent of 28.8-480mm. This version also offers optical image stabilization for reducing the effects of camera shake at longer focal lengths and slower shutter speeds. The lens also has a maximum aperture range of f/3.5-6.3 and benefits from the inclusion of one SLD and four FLD elements. Additionally, a Super Multi-Layer coating on the elements results in less flare and improved contrast.
Utilizing a Hyper Sonic Motor for autofocus ensures quick, quiet, and accurate focusing, all the way to the lens' minimum focus distance of just 15". A lens hood is included with the lens and it is compatible with Sigma's USB Dock for installing firmware updates and adjusting focus.
I already own this lens and wanted another one for my newer camera. I love Sigma lens. Great quality and reliability.
