It's important to have a high quality ultra-wide angle zoom in a lens kit. 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" at all focal lengths ensuring great creative potential. The wide angle view of up to 102? also offers greater freedom of expression.
