This week, I am attending the Dew Tour to take photos. The Dew Tour is a bike, skateboard and surfing event. I am taking my D7000 and have a question about 18-105 kit lense. I need a zoom lense but this is all i have currently, besides 35mm. I will be close to the event, literally next to where they will be performing (within 20 feet) What do you think I could do to get the best out of what I have? At night, I will have my SB 700 ext flash with me as well. Any help is greatly appreciated.
