Hi New owner of the E-P1 from today. Sorry for the noob question but here goes, is the 14-42 lens totally manual in operation apart from AF. I was under the impression that when the lens was fitted to the body and power was switched on the lens expanded and retracted when powered down, or am i confused with some thing else. BTW, i'm not referring to the zoom part of the lens, just how its all contained in the barrel. Apologies if i haven't worded the question very well, i'm sure someone knows what i'm trying to say. Thanks for any assistance. John.
