If you can afford it without a strain on your budget, I don't think you will regret it. It is by far the best lens available of its type for the K-1.
I have seen them used (like I got mine) as low as $1400. I paid a little more from a forum member and still saved a couple hundred bucks over new with no regrets.
My biggest problem is watching my DA*300mm and Tamron 70-200 F2.8 collecting dust. IF the DFA 150-450mm was a hair smaller and lighter, it would be a little easier to let the DA*300mm go, but in reality, the 300mm is a lot more compact and lighter and I can carry a few other lenses with it, while the DFA is a beast, and tends to dominate my bag for the day, and I usually only bring one other lens when I know I'm going to be using it mostly. It is not the kind of extra weight you want to carry on your shoulder all day for nothing, "just in case" you might need it. Picking my camera bag and what I'm going to put in it for the day is always a tough choice, heh.

That first shot with the FA35mm is great, the flower looks almost like reef brain coral.

In regards to AF tracking, I find that situations like this AF manages just fine. It could be a plane or a helicopter in the sky, or a bird flying against the sky or against the sea/river, the AF knows what to lock onto. I don't think Pentax has ever struggled in this regard. And because there is typically an abundance of light (at least here in Australia) you can stop down plenty (as there's not such a need to separate/isolate a bird flying in the sky from the sky with wide open DoF) and thus everything looks pretty sharp and decent.
Pentax's AF struggles only in a handful of action situations, and this isn't one of them imo. Stuff where a target is coming fast towards the user (on busy land), or fast paced sport with lots of 'stuff' going on in the scene making the contrast areas harder to identify is gonna be problematic for it. That and of course burst frame rates and buffer clearance. Let's not forget other brands will also not get good focus at times, but due to the higher burst rate and faster clearing of buffer they get more
chances to nail a good shot. So AF is just one aspect of that whole experience in getting a nice shot.
But really there are plenty of sports that are easily captured with Pentax's AF system, just a handful of those that aren't well suited. The bird or plane in the sky thing often gives the illusion of being something that would be tricky to capture and must therefore be an amazing AF situation, but in reality I think it's a situation that any camera handles very easily, it's quite favourable AF environment!
Absolutely excellent shots, I loved seeing the whole series
Thanks Bruce! Of course you are right, the background has a lot to do with focus lock and track, but even still, I think technique has a lot to do with it too, because there are people who blame the camera even with a clean background. I was just being chirpy and having fun. No oncoming weaving bicycles for me. ;-) Using Select 9, and CAF with the DFA 150-450mm set with the range limiter to 6m-Infinity does make it nice and quick. It makes the old DA55-300mm on my old classic K-5 seem like a snail in reverse by comparison.
