I am basically looking for verification of a decision. I am registered for a serious Patagonia photography workshop (Ian Plant). I have a D300 and assorted lenses and my E-M5 kit. I obviously want to return with great images and I feel that I can do so with my M4/3 kit as long as I practice good technique and post processing. Obviously I am investing a lot in the trip and want some reassurance that I do not need to suddenly get gear lust.
