I recently spent just over two weeks exploring Patagonia with my M (typ 240) and several lenses. It was a trip organized by an Australian landscape photographer I met on 500px. I've posted a few shots from the trip so far and will probably have more to share as I find time to work my way through my raw files.
This was with the new APO Summicron 50mm. I hope you enjoy it.
