Jason - I picked up on that in the review, also. It is interesting and could make the DA*200 more interesting - up until now all of the DA lenses weren't. It does seem like a sensible thing to do, to essentially copy another very successful lens.
I'm not sure I'd be tempted by the DA*300 or not - yesterday I was out shooting birds on a pond, and blew the focus on every single one, using the A*300. I think I need to check either my glasses, the dioper adjustment on the camera or something...
