This is a lens that will probably not appeal to professionals, and I guess a lot of people thinks a lens like the Sigma 18-200mm f/3.5-6.3 II DC OS HSM is not good enough for their last generation DSRL bodies (not true indeed, and we all know that it’s the photographer who makes the picture, not the gear). Nevertheless, this is a perfect travel lens. Light weighted (490g/17.3oz), with an 11.1x zoom range (18-200mm, on an APC-S sensor equivalent to 28-320mm), image stabilization, decent build quality, and fair performance. It has an HSM motor driving the zoom. Consider that this lens has a street price of $399 and you have the perfect travel lens. More after the break.
