F_Tokyo 1 The product description includes the Canon 8400F in the compatible product list but it's not!The film holder is longer than the glass of the scanner and it's not matching with the original marks on the scanner. In consequence the can not close and the scan quality can't be great.I will have to cut the film holder by hand to make this works properly.Avoid this product if you own a Canoscan 8400F, it's not usable.
