nice pictures, I am planning to buy K100D this afternoon, after weeks of research and reading through this forum, Final decision now is either to stick with the kit lens or buy tamron 18-200
The Tamron 18-200 has better built but the Sigma 18-200 is optically better.
But to maximise on coverage, perhaps you can consider the Tamron 18-250 instead. Sigma does not have one in that range yet, i think.
