There seems to be an old saw that if the shutter speed dial revolves when the shutter is released, one should wind first. This would appear to be true of LTM Leicas as well. But it seems that with Contax (or Kiev), the matter is in more dispute. I don't remember just where, but I read an article by a camera repairman who had worked on Contax/Kiev over 20 years, and he said he saw no reason to worry about it either way. Come to think of it,m that may have been right here on these forums some taime back.
