Ha Ha,shall i report you to the police about the stun?? :bsmilie: Anyway you all decide,24-50f4 uses 55mm filters,small size(slightly bigger than 50mm lens), close focusing at 0.35cm. 24-85f3.5-4.5 uses 62mm filters,bigger than 24-50f4, nearest focusing is 0.50cm. BTW, I'm using the 24-85 for wedding shoots and 24-50 for my personal shoots.......
