The photo is of a fruit bat, taken in centennial park, Sydney. Every night at dusk a few thousand fly out of their trees looking for something to eat. I've been trying for some time to catch one in flight, they move fast, and the light levels are very poor. I ended up capturing that at f4.5, using TAV, a shutter speed of 1/500, and exposure of -2.0ev. The ISO ended up at 3200.
For AF, I used AFC, with all 33 points. I've tried every combo of AF going, but that's the only combination I've found to work. If it's on the centre spot (which is what I usually use for birds), if the spot drifts off the bat for a fraction of a second, the focus goes way off. With AFC, the K-1/300 combo does a pretty good job at tracking the bats. The 2 main problems I've found are choosing a bat (from amongst many hundreds) that will end up flying overhead, and hoping that the K-1 will lock onto it quickly enough (without the DA300 doing a full focus hunt, by which time it will have flown overhead).
One of the worst parts about it is the time window. At 7:25 the first bat will appear. By 7:30 the exodus will be in full swing. By 7:35 it will be too dark.

I'm lucky enough to walk home from work every night through that bat storm, so I've been able to have a few practice runs. Most shots are terrible though. I've literally just purchased the DA200 in the hope that the slightly larger aperture will help. My next aim is to catch a bat drinking from the lake (you can see them flying in for a drink in the second image). I suspect that may take a year to accomplish
