Sigma AF 10-20mm F3.5 EX DC HSM - Nikon | Secondhand

Not the first ultra-wide zoom lens that Sigma has produced, the 10-20mm f3.5mm is their best quality, most user-friendly offering yet. The versatile zoom range is great for framing the more vast subjects that you might come across, while it features just enough zoom to stop you from moving around too much and to allow you to experiment with your compositions. A constant f3.5 aperture throughout ensures that no matter what focal length you are shooting at, you can let in the same amount of light, which results in consistently sharp handheld images.

Keeping you up with subjects on the move, in a discreet manner, the Sigma 10-20mm f3.5 lens is the beneficiary of Sigma’s fast and quiet HSM AF system. This system also allows for full-time manual focus override, so you can simply turn the focus ring to make critical adjustments to the focal point - you don’t need to change any settings. Aspherical, Extraordinary low dispersion and special low dispersion elements are all present in the optical construction, resulting in premium image quality throughout all usage, without sacrificing the portability of the lens.
