My wife and i have our d5100 for almost 2 years now, and i find some limitations of the camera as far as action/sports photography is concerned.
Can you describe these limitations in more detail? And which lens(es) are you currently using?
i only have the kit lens 18-55vr. I was in a gym last weekend covering an event.
In one instance, several muse were line up for judges to see. I was about 5 feet away, .
I set my aperture at F11, ISO at 800 shutter at 1/8. A bit dim in the gym so i had to use my
built in flash.
It took around 2 seconds, before the camera hit one shot after the other.
my buddies would click their cameras 3 times faster than me.
