I found an old Nikon Series E 50mm 1.8 prime in the attic in my house. It was in a case, sealed airtight and I looked through it and there didn't seem to be any mold or smears on the glass. Are there any Nikon digital bodies that this lens might work on? I've been trying to figure it out, and I think the D80 and up might be able to support it, but I'm not sure. Is the Series E lens even the F-mount?
