Description — Sigma 18-125mm f/3.5-5.6
The Sigma AF 18-125mm f/3.5-5.6 DC D is an APS-C format zoom lens built for DSLR systems, with a focal length range spanning 18mm to 125mm. That versatile range makes it a strong candidate as a walk-around lens for photographers who prefer to travel light with a single optic. The maximum aperture is f/3.5 at the wide end, stepping down to f/5.6 at 125mm, which is a standard characteristic of this class of zoom lens.
Both autofocus and manual focus are supported, and the lens is compatible with Canon EF, Nikon F, Sony A, and Pentax K mounts, covering a wide range of APS-C DSLR bodies. The 62mm filter thread makes accessory filters easy to source. At just 385g, this lens keeps your kit bag light.
Note that image stabilization is not included, so handheld shooting at longer focal lengths will rely on good technique or in-body stabilization if available on your camera.
