Question about Reflecta x7 scan

Halo,
for mechanical reasons alone, it is not possible to scan 120 film. Also, the scale of the image cannot be changed. With smaller formats, the image is simply cropped.
This device is not recommended for slides, as the contrast range cannot be adjusted and there is always an increase in contrast, which, together with the already existing increase in contrast on slides, exceeds the exposure latitude. For negatives (b/w and colour), however, it is good value for money.
