Sony A35 & 16-55/2.8 for wedding ?
Wedding shots with an entry-level camera? Some people would get scared off...
The last wedding dinner I went to, the hired photographer had 2 full frame bodies, a 50/1.4 on one, and a wide angle zoom on the other, with a 70-200 in tow. Both bodies equipped with SB-900s, and all around the wedding hall corners he had placed 5 SB-900s, each one triggered wirelessly, to fill the area when he shot.
