I am looking to purchase a new lens for my wifes dslr. i have been looking for something to replace the stock lens and seemto have arrived at a choice of two.
1) Sigma 18-125mm f3.5-5.6 DC OS HSM
2) Canon EF - Zoom lens - 28 mm - 135 mm - f/3.5-5.6 IS USM
Both around the same price and just like to know if anyones has used and thier opinions.
