The Voigtlander 15mm f/4.5 is one of my favorite lenses, due to its small size, image quality and price. A great lens which I have used extensively with my film rangefinders, and now also with the Sony A7s.
I used the Leica M7 with Fuji Superia XTRA-400, a saturated film, not on par with professional emulsions, but with a look I like very much. On the Leica, you will need a 15mm viewfinder on the hot shoe to frame correctly.
