During my last wedding photo shoot tat I help my Frez, I did bring along the Len tat I had. 50 1.8, 18-270 PZD , 28-80. But due to alot alot of unexpected thing happen I end up only using 18-270 most of the time n shoot all the way. Haiz.. It a long story.. Lucky thing is tat I set my Frez expectation low or maybe my frez expectation isnt high so the end result still not under deliver. Most important things, juz shoot as many pic as u can. There will be definitely be at least 1 pic out of every 3 pics u shoot can be use.
