<p>I have had a Fuji 645 Professional for many years now. I recently purchased a Fuji 645zi as I wanted a second camera and the zoom. I have had problems with the film advance though. I load the film same way as the 645, film advanced to the spot that it says on the back matching the point on the back of the camera. However when you close the back it doesn't auto advance the film. I then have to fiddle with it but auto advancing the film myself, it does then eventually auto-advance, but I have lost at least four frames per roll and often get light leaks. Can anyone advise ?</p>
