These now antique Kodak 4050 scanners are beasts! 4050s have heavy steel frames. It takes three men to move one! The heavy steel frame keeps the high quality optics precisely aligned so the focus is exact and keeps the details of each image in exceptionally sharp focus unless you are used to modern digital camera images, in which case the scans from the 4050 look like they are coming through a film of mud.

When March Air force Base surplussed out their 4050 they had been using to scan the film from the U2 spy aircraft I was able to purchase it from a surplus dealer in the San Fernando valley. So many of my images were scanned on the very same scanner the U2s' images were scanned with! They are dogs now compared to modern digital camera technology. No wonder the Defense Department went digital years ago. Of course, they also had the motivation to have a workflow that allowed them to transmit the images digitally to Earth from satellites without having to parachute film or bring film back in Blackbird aircraft to Earth.
