The Sigma 8-16mm f/4.5-5.6 DC HSM is an ultra-wide-angle lens suitable for single-lens reflex cameras with an APS-C sensor. The wide viewing angle of 114.5 to 75.7 degrees offers different perspectives. You can photograph high towers, trees, or mountains from a frog perspective for a creative effect in your photos. With the minimum focal distance of 24cm, you can get on top of the smallest subjects. Easily capture ladybugs or daisies in the grass. The lens has a silent autofocus motor, so you can focus on your subject silently. This prevents your subject from becoming scared and running away before you can take a picture.
