its regarding about lens... i just feels that my 55-200 is kinda of loose in a way its easier to turn from 55 to 200 easier than 18-55 which is abit tighter.. i rem there was once i accidentally pulled the lens out from my bag holding at the tip of the lens which is around the filter there or below and it just extend to the max range -.- is there anyway i can tighten it? i know its abit confusing hope u guys understand. sorry for the poor english
