I'd be interested in a similar test that would include MF RF's and the Hassy SWC. As Ole states, Tripods may be a best practice, but not always practical. I have enlarged handheld images to 20x20 from 6x6 negs and they were plenty sharp. I have also enlarged 6x6 negs to 20x20 that upon inspection exhibited some camera shake. The final product may not have suffered because the image was strong.
