We recently ran into this topic again within another thread.
I have acquired a Sinar adhesive 8x10 holder some time ago and it's definitely a Fidelity holder with machined guides (and propably selected for tighter tolerances). So what about redesigning conventional holders (I've heard the adhesive tape can be bought from 3M) - or is somebody interested in making wooden holders compensating even for the height difference (caused by the thickness of the tape)?
I wonder why not all holders use adhesive tapes? Film is held perfectly, no guides needed, easier loading, even the flap isn't absolutely necessary anymore and the tape helds dust as well. Seems to the superior design, IMHO?
What am I missing?
