Since getting my first Barnack Leica just over a year ago, I have found that they work remarkably well for me, so much so that I've acquired two more since then. I now have two IIIcs and a IIIg. The IIIg is more capable in regular use, at least in stock form; the IIIcs normally have external finders mounted to compensate for the small viewfinders. All are a real pleasure to use, and I have become acclimated with their quirks to the point that they seem quite natural now.
