Yep, back in October when it was released. I don't expect there'd be many used ones up for grabs. (Not yet anyway, and when I look at some of the prices that most people want for used glass on TM I'd rather spend a bit extra and get the peace of mind of buying new.)
This is my first foray into ILC from point and shoot. So I'm trying to be disciplined about my spending. So will learn with kit lense as much as I can. That said the extra reach would be nice as I like to take photo and video of my friends playing golf. But we'll see how I go with the 18-135mm first.
