I have two lens Nikkor 55-200 mm f/4-5.6G IF-ED and Nikkor 18-55mm VR. My sister's marriage is nearing so I'm planning on taking pictures. Though professional photographers will be there, I still want my capture to be counted. I will be capturing the function at home (Indian marriage). Function will be of 3 to 4 days. Sometimes it will be a lighted situation while other times the light will be less. What other lenses would it require to have sharp closeup photos, or even at some distance during daytime and night both in both the lighting and less light situation? (I'm experimenting with bounce off flash light these days also). Do I need any other lenses for the event or is the one I have enough for the purpose?
