I have been asked to shoot a dance recital with my AF100A. I think I will use 10806P @ 24mps, but do I use a shutter speed of 60th second or the 100th sec choice for shutter speed. I'm shooting it as video not film mode. I have not used the AF100A much, just bought it from B&H on sale for $1495. I will be using a Pana lens 25mm1.4F.
