This is built just like the Wista 4x5 screen found on models such as the VX and SP.
Bright, contrasty, and sometimes you don't even need to use the viewing hood, the image just pops out.
It is a GG/fresnel in one piece, with a clear glass overlay.
I bought this recently from a forum member, hoping to make it fit my Toyo 810M, but it didn't work, and I certainly didn't want to damage such a beautiful screen by adapting it to a camera that it didn't fit.
The previous owner bought it new, but never installed it.
I bought it and did not install it.
Screen measures 7 7/8 inches wide, and 9 7/8 inches long, or 201mm x 251mm.
Asking $70 plus shipping
