Cool stuff. I just picked up a Zeiss Ikon Nettar 516/2 from a thrift shop. It has a Novar lens. I shot a roll of Delta 100 which turned out surprisingly well considering my nearly complete ignorance of medium format, b&w film, and scale focusing. The next roll will be Portra 400 NC in order to be able to crank up the shutter speed and stop down a bit. That should help with focusing a bit. All in all it was great fun to stop and really think about each shot, especially since this is a 6x9 camera and you only get 8 shots per roll.
