I had an opportunity to use a rather unique focusing cloth today. It resembles a black slitted skirt with an elastic waist band. You place the elastic part ar ound your head and pull the open portion over the the back of the camera. The s lit faces down so you can get your hands and loupe inside. Very light tight and impervious to wind problems. The owner said he got this from Zone VI, so I che cked Calumet's web site, but alas, no such item. Anyone have a clue where I cou ld buy one of these?
