The Sigma 24-105mm F4 DG OS HSM Art lens is a high-resolution zoom lens designed for high-resolution digital cameras.

This premium lens is suitable for full frame cameras and will also work with APS-C sensors with an effective increase in focal length.

The Sigma 24-105mm F4 DG OS HSM measures 4.3” long and 3.5” in diameter, and it weighs 31.2 oz.

The constant aperture ranges from f/4 to f/22, utilizes 9 diaphragm blades.

The front accepts 82mm filters, while a petal-shaped hood, front and rear lens caps, and a padded case are included.

Autofocus is fast and silent with Sigma’s Hyper-Sonic Motor (HSM).

Movement of the elements is internal, meaning the lens length does not change throughout focusing.

The front element does not rotate during zooming or focusing.

And, no matter the position of the camera, including pointed straight up or down, lens creep does not occur.
