I bought some time on a hasselblad medium format scanner (took fucking ages)
The results are good, as you'd expect. However can I tell the difference between that and me putting the negatives on a decent softbox and using a fancy camera to take a picture? yes, but not by much.
I think the main issue is film registration, that is getting the film to be flat and "co-planar" to the lens so the whole frame is sharp.
My negatives are slightly warped, so they really need a frame to make sure they are perfectly flat. But for instagram, they are close enough.
However scanning more than a few pictures is a massive pain in the arse. If I was scanning film regularly, then this is what I'd want, and its cheaper than the competition.
Assuming that its actually any good, I haven't seen any scans yet.
