"The vibration issue is supposedly with low shutters
speeds (from 1/30 to 1 second), and specially combined
with long lenses (wich I never plan to own or use)"
Shooting handheld with the old 6X7 it actually jumped in my hands. The best
shot I ever made was a sunset on Lake Champlain where, having no tripod, I
set the camera on a park bench, put my hat over the lens, opened the
shutter with a cable release, removed the hat, counted to ten, replaced the
hat over the lens and closed the shutter. Who needs MLU?
Eventually, I too converted to Rolleiflex and Fuji 645 and 690 rangefinders.
