I had a DA* 60-250 years ago, but didn't bond with it. There were no gripes about the image quality, but in the days before the K-1 and the new monster telephoto zooms I found the size and weight, the extension while zooming, and the focus breathing to be significant turn-offs.
I'll always have some specialty primes of course, and the DFA* 70-200 and DFA 150-450 still fill their respective niches better than anything, but now I plan to ditch the consumer zooms and old manual glass I see a 60-250 sized hole in my life once again. With a two body kit (KP and K-1 Mark II), I see it complimenting my DA* 11-18 and DFA 24-70 better than anything else.
Feel free to talk me out of it. Or not
