It also includes Sigma’s super multilayer coating to minimize flares and ghosting. Auto focus is processed by ultrasonic motor, which is fast and very quiet. The large switch on the side of the barrel engages the manual focusing, and the second smaller switch controls the optical image stabilization. The nine lobed circular aperture is designed to provide a smooth, blurry background, and the lens can be focused to a minimum distance of 45cm.

Optically, sigma 24-105mm F4 DG OS HSM lens is a very capable performer. When it’s wide open, the corners of the image are a little soft, but when it stops at f / 8 or F / 11, the lens is very clear almost all over the picture.

This vignetting may be visually unpleasant, but it can almost be eliminated by turning off the lens. It is stronger at wide angles than at telephoto.
