Dpreview on Sigma 18-200mm F3.5-6.3 DC OS HSM Lens

Dpreview has reviewed the Sigma 18-200mm F3.5-6.3 DC OS HSM lens and have mixed feelings about it.  While  the 'do-it-all' travel lens does come recommended however at times the lens was a sub-par performer especially when it came to optical stabilization.T he F6.3 maximum aperture at 200mm also compromises autofocus performance according to the reviewer.

Says the reviewer:
“Overall, then, this isn't a lens for pixel-peepers who above all else demand critical corner-to-corner sharpness in every shot. But for more normal users looking for a versatile, all-in-one travel lens within a budget”.
