Introduction
Designed for APS-C reflex sensors, the Sigma 18-250mm F3.5-6.3 DC Macro OS HSM shoots like a 27-375mm (and like a 29-400mm on Canon cameras with focal length coefficients of 1.6x). Very versatile, this lens qualifies as a macro thanks to its 29-cm miminum focusing distance at all focal lengths. As a telephoto lens, it provides a reproduction ratio of 1:2.9 - the equivalent of 1:2 using an APS-C. The lens barrel has a reproduction ratio scale printed on its side.A travel and macro lensDesigned for APS-C reflex sensors,
