Sigma 18-200mm Opening Shots

After using the 18-55mm kit lens for a reasonable period of time, bought a new lens : Sigma 18-200mm f/3.5-6.3 DC AF OS. Not sure whether this lens will be optically 'a lot' better than the previous one, but would love to make use of the extended zoom range. Being not that serious (and lazy) to carry and use multiple lenses, this was the most economical choice.
