A Question on Screens

#1 by Robert Crewdson , Sun Oct 07, 2018 12:38 pm

At present I am limited to a 50 inch screen, which I fill from a distance of about 11 or 11 and half feet, with a 25mm lens. What distance would I need to be able to fill a 70 inch screen?

Are we talking about 16 mm, Robert?

With the 1" lens the distance would be a tad over 15ft. (67" at 15ft).
