Yeatzee,
This was not shot with a DA* lens. Using my other camera as I await the return of my K5. The lens was a Nikon 300mm (f/4). Not sure if that's 100% kosher for posting, but I didn't think folks would mind. As for comparisons, the Nikon 300mm (f/4) and Pentax DA* 300mm are very similar. Based on my experience I would give a very slight edge in sharpness to the Nikon, and the edge in bokeh to the Pentax. The Pentax also has a better built lens hood, though it's not a huge issue.
Pete
