K-70 uses Prime M II
K-5iis uses Prime II
K-3 uses Prime III
KP uses Prime IV
K-1 uses Prime IV also
K-50 uses Prime M
Newer processer unit... plus the addition of the Accelerator Unit, which helps reduce noise on high ISO images, pixel shift (which I absolutely love for macros , flowers and landscapes. Upgrades in almost every aspect of operation.

Originally posted by iheiramo I would go the other way. I think 1/500 ain't fast enough as on some shots it's visible that it's not fast enough to freeze the action. As lens is already wide open ISO need to be higher for faster exposure. There should be enough DOF at f2.8.
K30 M100/2.8 ISO3200 f2.8 1/1250:
But to me many of the shots look to be out of focus for some reason.
Yes, that's curious given the shutter speed. And the faster shutter speed is definitely something to experiment with. Back in the day we used to say 1/100s was enough to freeze human self powered action, but if you are trying to use shutter speed to make up for camera movement, you need a lot faster. I'd try stabilizing my camera before I'd boost my shutter speed. If the camera is stable, 1/250s is more than enough to freeze action, but, failing that, a higher shutter speed can help. These days if you can find the sweet spot for your camera's SR you can get away with a lot, but looks to me like the OP is surpassing what the camera can handle.
Making sure focus conformation is on will slow down your burst speed, and take the shutter release out of your hands as sometimes when you push the release, the camera confirms focus before firing the shutter, but in situations like this, given the problems at hand, it might be better to have it turned on. So the AF:S setting should be set to "Focus priority" not "release priority." That might help.
When I shot volley ball before the days of AF I'd generally set my camera to an area a spiker was likely to go up and shoot when they came into that area. But I also was shooting a fast 50 and had court side access, so things were a lot different.
