Excellent condition. Has spent most of its life in the box as I have only used a few times.

Selling as no longer use my Nikon.

Info taken from Sigma-

Sigma's 10-20mm F4-5.6 EX DC ultra-wide zoom lens for digital SLR cameras is ideal for landscape photography, building interiors, group and party pictures and so much more. Great for working with close foreground subjects as this lens features a minimum focusing distance of 9.4-inch at all focal lengths ensuring great creative potential. The wide angle view of up to 102º also offers greater freedom of expression.
