Original F1 Prisms

[wmichaelb]

I had the good fortune to pick up an original mechanical F1 for a good price; but the focusing screen is chipped. Does anyone know of a web site or document that lists the focusing screens that were made for the F1 so that I can figure out which one to replace it with?

Thanks!

Not sure of which website but the original screen is screen "E". I

have an F-1n and that is what was supplied with mine.

Lots of info on the old F-1. They also have a page on the New F-1.

Also any of the earlier Carl Shipman books on Canons has the list of

focusing screens. A source for these books is Finger Lakes Photo

books at http://www.photomall.com/flpbks.htm. Make sure that you get

an earlier one that covers the F-1/F-1n. The later books dropped that

for the New F-1.

Michael,

I quote from the F-1 manual, pg 53, Focusing Screens: "Nine types of

focusing screens are available: Focusing Screen A (microprism type),

B (split-image type), C (all-matte type), D (matte/section type), E

(split-image/microprism), F (microprism/large aperture lenses), G

(microprism/small aperture lenses), H (matte/scale) and I (double

cross-hair reticule). Ususally, the F-1 is sold with Focusing Screen

E."

Another thing is there were two types of screens for the F-1 and F-1n,

the normal and the L screens. The L screens are much brighter, like

the later laser etched screens.
