I am perplexed by the imagination that digital photography is the end it all for film. Sure, it is, for the 35mm format, and indeed, the medium format too.
But I know of large format photographers who do exactly that (carry the tripod an and the 4" x 5" film etc).
Why do i bring up large format? Yes, I am certain that we would have large format digital back technology that is commercially viable in the future. But even with the best lenses and the best digital back, there are other things to master. One example would be the adjustment of both the lens plane and the film plane in accordance to the Scheimpflug principle. This is one thing that the simple presence of a digital sensor and an autofocus module can solve.
As for large format photographers, there aren't many left, and but the few that are left are good at what they do. Ansel Adams, the photographer mentioned earlier, was one of them.
Please note that the 36mm X 24mm format is called the 135 format and not the commonly misunderstood 35mm format which actually refers to a particular film format that measures 35mm in width.
