Got some shots for this weeks project today. Below are the settings, the description of the settings from the Nikon manual and my rationale for using these settings
AFC: Continuous Servo AF - Camera focuses continuously while shutter release button is pressed halfway. If subject moves, camera Will engage predictive focus tracking... and adjust focus as necessary. Shutter can be released whether or not subject is in focus
9 point Dynamic area AF: Choose this when there is time to compose the photo or when photographing subjects that are moving predictably.
The above 2 settings made sense to me in order to photograph cars moving on the highway or in this case a horse and buggy coming towards me. I did some cars and trucks BUT they are boring. I really wouldn't need AFC for a horse and buggy, they move slow enough that I'm sure I could refocus using AFS (for stationary subjects) but this seems to work and it's much easier than having to stop and refocus all the time. Actually as I write this I'm thinking that AFC is the better choice. I believe focus locks when the shutter is released with AFS SO that means that there will always be movement between the time I lock the focus and the time I press the shutter. I don't know how fast the focus calculations are with AFC BUT I suppose there is more of a chance of keeping even a slow moving subject sharp with AFC.
Continuous shooting low speed: While shutter release button is held down, camera records 1-5 frames per second. Frame rate can be chosen using Custom Settings CL mode shooting speed.
Very interesting. This was firing much faster than I needed so I controlled the rate myself by keeping the shutter release half pressed but only releasing the shutter when I was ready. I will have to set up the mode shooting speed - didn't know I could do that.
EXIF:
All shot were taken in AV mode f 5.6. I opened up the lens because in my mind this seemed like a better way to test if the camera was tracking. I'm really not sure about this???? It just seems that if the lens was closed down then the greater DOF could be what's keeping things in Focus. In a real shot, I would want the increased DOF, but for the test I thought the shallower the better. Not sure if that makes sense but they are all taken at 5.6
because there was only a few seconds between each shot EXIF is the same for each shot
1/500s: ISO 800: 200mm: +1/3 EV
Focus point should be on the horses face.
I saw the horse and buggy coming in the distance and framed the shot and picked the focus point I would want to use so I could take the first shot just before the horse got to the bend. I figured I would be able to keep shooting until the horse was rounding the bend. I didn't have enough time to move closer and zoom out or I would have, so all shots are taken at 200mm
Well, I don't know if that helps anyone else, but it helped me get it burned in my brain by typing it out. So, the results are not wonderful, but for a first try I'm happy that the camera is doing what it is supposed to do and I think with practise and experience. I will get better with action shots.
And now for your viewing pleasure, here they are:

Suggestions welcome. I'll be doing this again... practise practise practise. I want to stay on the same focus settings though.
These look to me like the focus gets better as the subject gets closer, which is fine I guess and perhaps normal for this lens. I never have liked shots where I had to focus on something in the distance. I don't know if it is the camera or the lens or if that's just the way things are.
Anyway if I missed any settings or didn't explain something properly let me know.
