Yes, it's okay. Just a couple of pieces of plastic which probably cost about two cents to make. Seems a little flimsy, but it does the job. I think I'm going to keep it. I've been scanning some 127 negatives from 1968, none of which are very sharp anyway, since they were made with a Brownie reflex with a shutter which was starting to go bad. I made the scans at 3600x3600 pixels, which is optimistic. They should print okay at about 5x5 inches.
Our son Don was born in June, 1968, and realizing that the Brownie was giving up the ghost, I looked around for another camera and got a 126 Instamatic. That, strange as it may seem, was the beginning of my career. I bought the August, 1968 issue of Popular Photography, which was followed by more magazines and more and better cameras, and now, here I am, still working, but winding down a 45-year career as a commercial and wedding photographer.
I'm going to order a 126-format negative holder so I can scan some of those 126 negatives.
Here's a scan from a 127 neg using the film holder in my Epson Perfection 4990 PHOTO.
