Well, after further use of my DA200 I think I might have been a little pre mature with my initial judgement of the lens. I'm loving' it! ! And, since this thread has sort of "gone to the birds", I thought I would post a pic I got today:

I guess I have done a really bad job of explaining myself. I was just trying to test the autofocus performance of a new lens. I have shot strictly manual focus for over 25 years so I certainly don't "think fast AF speed is the only factor in getting great images".
Thanks to all that have responded.

Again, please let me clarify - bird photos are not my priority. They just happen to be my first test subject of the autofocus capabilities of my new DA 200 and I'm afraid it flunked the test. Though it is beautiful lens and one I hoped would be "good enough", I have found(so far) that it can't compete with newer designs.
I'm sure that many of us can get good photos on any lens- that is not the point! As one who has come from the film era of MF lens, I want any new purchases to maximize the benefits of AF and I'm afraid I made the wrong choice with the DA200.

Stevebrot, I am not expecting the lens to "choose the subject". I am capable of doing that. I am just comparing the auto focus performance of the DA200 to my 28-105 "kit lens" on my K1 or even my 18-55mm on my K200 and I am disappointed . I am requesting some useful info that might help me, not criticism.
And, the birds at the feeder are just an example, not a big priority for me. Sorry if I was not clear on that.

Normhead, I just want to say I respect and appreciate your comments and you have proven what you can accomplish with the DA200. I just have to wonder what you(or I) can accomplish with something like the FA 70-200 instead.

Thanks for comments so far. I am using Spot mode. My problem is not with the auto focus speed - the autofocus would not lock on at all with birds at my feeder. Of course they were moving some but they were NOT in flight. It will focus on large stationary objects with a little bit of hesitation but I have a MF 200mm f2.5 that I can use for that. I bought the DA200 for its autofocus!
So, DDorm, you also have found that AFS works better? I wonder why?
Maybe I am just going to have to bite the bullet and buy the FDA 70-200 to get adequate performance.

I just received a DA200 purchased from a forum member. I was blown away be the quality, size and weight of this lens, BUT, as I experimented with the auto focus with some birds at my feeder I ran into some issues. Using the default setting of AF.C for the Phase Detection AF, the auto focus will not lock on to the birds. I Switched to AF.S and it was better and I was able to get some nicely focused shots but the AF does not function as well as my DFA 28-105. Is this normal? I do have more experimenting to do before I reach a judgment on this lens, but any suggestions? I want so badly for this lens to work but I am having my doubts. I would appreciate any help.
