Nikon F3, dim viewfinder?
So I picked up what might be the worlds most heavily used, brassed up, worn to crap Nikon F3 at a camera meet in trade for a broken AE-1/50mm outfit. I absolutely ADORE the solid (and "broken in" feel :cool:) of this body compared to my FE2 and FG but one thing is kinda annoying me, the viewfinder is incredibly dim by comparison and has what I would call a vignetted appearance. I'm wondering if this is something plaguing my specific finder/screen combo (an E type grid and standard prism) or is it just part of the TTL metering design? The mirror has that weird looking keyhole pattern that best I can tell from searching the google, allows the light to pass through the mirror and onto the meter.
