Hi Moose, I am new to your site, and I have already learned so much, so thanks. I have been asked by my daughters CCD director to do a group photo at our church and I said yes thinking it would be about 15-20 people. That number is now at about 50-60 persons! Help! I only have a Nikon D5100 with the af-s 18-55mm lens, a tripod and an SB600 speed light. The group photo is indoors. I did a test shot in the empty church, and the lighting and flash combo worked well. I am more concerned with the focus of such a large group. I am willing to buy a better lens for group photos and possibly a flash. What would you recommend?
