I do not know if the obsolete 127 format is considered medium format or not but my the years of shooting "super slides" (We called them 2x2s.) certainly out did the prevailing 35mm slides. Though 127 was a common format for the point and shoot cameras, the TLRs were most often 120 format and beyond the price range of a high school student. However the Yashica 44LM was not. I burned a lot of Ektachrome through that camera, before moving on to an SLR with interchangeable lenses. I am curious how many still shoot from the hip with a TLR. Though the judicious use of a cigar cutter, a roll of 120 and a changing bag, I produced a roll of so 127 film. It loaded into the camera okay; now I am anxious to go forth and take pictures.
