The 70-300mm F4-5.6 DG Macro from Sigma is a high-quality,compact variable aperture zoom lens lens. It’s perfect for shooting candid portraiture, vacations, youth sports, and even your kids playing in the backyard. In fact, it is one of our most popular lenses!
Available in many popular mounts, his lens is compatible with full frame digital SLR cameras, but may also be used with smaller APS-c size sensors with a corresponding increase in focal length to about 100 to 450mm with most cameras-and that means more effective reach when paired with most popular APS-C Digital cameras. And it comes with a three-year warranty, too.
