Not much movement on this thread - no love for the M? As stated earlier I use it strictly as a point and shoot camera with the small 22 pancake lens (I will not buy additional lenses).
Last night I led a night photography workshop for a local camera club and threw it in my jacket pocket just for snapshots of the group (to post on my photography FB page, etc). This is unadjusted JPEG, except for downsizing and watermark.
