Started shooting LF with vintage soft focus barrel lenses mounted on old wooden cameras with Packard shutters about year and a half ago. Recently I've started to shoot with sharp focus lenses on these same cameras, e.g., 8x10 Kodak 2D and 8x10 Century studio camera. As a test, I shot the same sharp focus lens that is mounted in smooth running leaf shutter using the leaf shutter and using the Packard shutter mounted in my cameras. I had expected the there would be some detectable loss in sharpness between the negatives shot using the Packard shutter due to vibration, i.e., the Packard shutter operation would create vibration induced motion blur where the leaf shutter would create observably less. The result is that all of the images are sharp and I can not observe any difference in the images shot with the leaf shutter or the Packard shutter on either the field camera, an 8x10 Kodak 2D, or the studio camera, an 8x10 Century Universal.
Is this observation consistent with the experience of others?
