Hi Everyone,

I'm new to the forum and digital photography. I've been doing dog agility for quite a while now and would like some suggestions on suitable telephotos for shooting at agility trials. I'm using a Nikon D200 and currently have a 70-210 f4-5.6 but all the trials around here are in covered horse arenas and I'm thinking I will need something both longer and faster. What focal length do you guys find ideal for shooting agility trials?

Thanks!
Greg
