Hello

I am looking to get a zoom lens for my K20D. These lenses will be used in low light nightclub/live band situation.

Can someone point me the right direction for a fast lens that I can use when a distance away from the stage but keep the ISO down.

Also can si there anyone out there that has used a K20D in this situation and can suggest any tips or tricks.

At the moment I only have the standard 18-55mm stock lens and a 30-300mm Tamaron.
