This forum seems to be dominated by "M" series cameras...no offense intended; hope none taken! I had an M3 and an M6 and both seemed uncomfortable to me...to ME...for whatever reason. I use SLR systems for formal photography as well as medium format. These are big and very "visible." <p> I recently (very recently...like a week ago!) acquired a nearly mint IIIF and a Imarec VIOOH viewer. I soon discovered that all I need is a high speed film (400-3200), zone focus from infinity to 8' at f/16 (more with a 35 lens), totally enclose the entire camera with my hands, leaving only the tip of the lens and viewer exposed, and I can move wherever and whenever without bothering anyone. New adventures! <p> Has anyone else discovered this particular attribute of the early Leica cameras? There are very few III series Leica forums for "show and tell!"
