I've shot quite a lot of tennis at the Australian albeit with K3 and Sigma 70-200mm F2.8 so a bit of a different scenario to you.
However what I would do in your situation is:
- Shoot jpg with all auto corrections off (for maximum frames per second);
- Shoot in manual mode (dial in your shutter speed, iso and aperture, again so the camera at operate at maximum speed);
- Shoot F6.3 or F8 for maximum sharpness (this is based on supplied lens, if it was an F2.8 I would have suggested F4)
- Use one of the center AF points, ie, manually select the AF point and don't rely on the camera;
- Shoot in AF-S mode (AF-C is too unreliable);
- Select high frames continuous shooting mode.
For what's it's worth which may not be much given my camera/lens combo, here is some of what I have achieved:
Oz Open 1 Oz Open 2 Oz Open 3 Oz Open 4 Oz Open 5
Best of luck. Shooting sports is kind of fun although I wouldn't want to do it all of the time.
