I think the DA*200 and the HD 1.4X TC makes an excellent pair. Whether it
"affects IQ much" can give rise to endless debates. I guess you can always find 'something' to point your fingers at, if you are a die-hard pixel peeper, but you do get a gain in spatial resolution with this TC.
Anyway, here are some more "real pictures" for you to make your own judgement (cross-posted from the DA* Club):

Regarding AF I find it very reliable on as well my K-5 as my K-3. You can even auto focus on the not-too-faint stars! And I certainly don't complain myself about AF-speed on the K-3, but others may have more demanding requirements here?
