Sigma 300-800mm F/5.6 DG Unboxing; Focusing Speed

This lens has been with me for more than a year, but just for request, I will be sharing with the world how the tribk case looks like etc when you buy this bazooka. I have also recorded the auto focusing speed in this video. I am only lacking hte Polariser filter which I lost it. (I dont even use it anyway as Wildlife photography always has insufficient lighting). From my personal experience with using my most used lens, the focus speed is fast enough for flight shots of big birds like herons, eagles, storks etc. It is also fast enough to track humans running at a 100metre sprint, and taking vehicles moving at F1 speed. Anything faster, Sigma's HSM speed is not fast enough to track much more rapid moving subjects. My wildlife photos taken with this lens @ www.kenniepan.com Questions comments feel free to write in. Sorry about the video Out-of-Focusedness- shaking etc, it is rather difficult to hold a camera steadily while trying to move something.
