I got a reply from Skier, in which the representative says the following:
- That is a good suggestion. There is currently no production exclusive to negatives of 28×28mm and 13×17mm. You can use 135 film holder to scan negatives of 28×28mm and 13×17mm first.
I’m not sure how that could bring optimal results, as the film strip assumably wouldn’t be supported from all sides. Anyway, I’ll probably order my film holders from Negative Solutions.
Thanks again argaach for your help
