Wonder if I could get some of your expert opinions on this?
I do quite a lot of amateur sport (kids stuff mainly but not exclusively) - football in the winter and cricket in the summer. I use the MD10 on my D300 and have always noticed the variability in the fps I get in burst mode. Now I understand this in football when the light is poorer and the action is faster moving but I see it with cricket in decent light as well.
I have both a general question and a specific one. The former is to ask what the variables are that influence the burst rate achieved in real-world usage (I'm guessing that AF is involved heavily) and what I can do to maximise what I get.
The specific questions is whether the length of time I hold the focus before pressing the shutter can influence this. I feel that with cricket, if I hold the focus in the batsman for several seconds it adversely effects the burst rate achieved. Could this be possible?
It doesn't actually bother me that much, but I am interested in understanding what goes on inside...
