They could do 8mm or Super 8 film if they had the right gate but many times these gates cost $100,000 each or more and they didn’t have enough volume to warrant the costs.
Recently some lower cost ($100,000 plus) film scanners have come available for Regular 8mm and Super 8 film. These machines have many of the same benefits and quality of the professional film scanners of the past but are focused on smaller gauge formats like Regular 8mm and Super 8 film.
