There is only one other camera that felt perfect and didn't make me wish I was holding the F3 instead - Leicaflex SL - but its finder was so yellow that it was pretty much unusable. I would love to get my hands on another in good condition, but that would be costly as I have only two lenses for it (Angenieux 45-90/2.8 and Leitz Macro-Elmarit 60/2.8).
Is it possible to bleach the yellow out of the viewfinder by standing it in the sun for a few days? I see that recommended for yellowed lenses all the time.
Right now in Spain they're holding the Running of the Bulls,
followed by the Soiling of the Pants,
and the Burying of the Idiots.
