Kodak Aero Ektar 6,3/48" A 48" lens for a 9x18 camera. This thing is 200 LBS. It appears to of been used by the USAF. I would guess it was used for Ariel photography. There is a knob in the side to color shift the lens, I am sure this thing was ton and tons of money when built new cant imagine the wonderful glass they use today



I do not post a link to an Ebay item for anything other than conversation. The coverage is listed as 510mm, look how it dwarfs the 35mm roll of film as wells as the Canon camera. A whole new meaning to ULF dont you think. Would make a nice field camera dont you think?
