I think this thread started with ground glass for Speed Graphics and if
you want to use one for a Speed you have to be a little careful where you
put it.
Most Anniversaries and Some Pacemaker Speeds did use fresnel or "Ektalite
Field lenses" as Graflex called them. The ground glass on a Speed is
loaded from the back, and if you installed a fresnel where there wasn't
one, you'll shift the ground glass out of position the thickness of the
fresnel.
