Epson stopped making their flatbeds that do film, reportedly because they can’t get the CCDs anymore. That may be a rumor.
The result is they go for 2x MSRP on eBay for models that are many years old. Because that’s all that exists.
Without that, you can buy the kind of scanner meant for a photo lab ($$$$$), DIY it with a DSLR ($$$ if you don’t have one), or pay your a lab a lot per roll and hope they do a good job.
I’m not saying it’s a giant market but it certainly seems to me like there’s enough of one that it could support a small product.
You can get brand new Plustek OpticFilm scanners for 35mm and smaller starting around $300, and there are plenty of other options above that. Plus the DIY.
I’m sure 35mm is easier to make and certainly a bigger market but it’s also a lot more crowded.
I expect their specs are far better than the $300 one I’ve mentioned, I don’t know enough to know. But medium format people are desperate for anything.
