They have hired a professional photog, but want me to take some photos, too. And they couldn't have stopped me. What 1 lens would you suggest I use - 17-55? My options are the 17-55, Tokina 12-24 f4, Tamron 90 f2.8, 50 f1.8, & 70-300VR. I will also bring along the SB-800. It's an afternoon wedding, in an open air setting, at a beach house. Thanks.
