I am looking for a good 400 speed film for vacation use in my Hasselblad. The TMY 400 film is very stiff, is very curled the camera tends to space the frames farther apart. It is also difficult to load on Jobo plastic reels but works with difficulty on Nikor stainless steel reels. The negatives look very good and sharp. I compared the thickness of the film to TMX 100 and they are almost the same.
