From reviews, it seems the Sony 18-200 isn't that great. The Sony 18-250 is a much better lens as far as the superzooms go. The 75-300 is not really good. I got the Minolta Version and after little use I've retired it and it now serves as a paperweight.

Like pisco, I've also ended up going with the cz16-80 and beercan combo. I've also added the 11-18 at the wide end. I've been debating the new 70-300 G SSM, but I feel like I'd still use the beercan more often. Just can't beat that incredible bokeh..
