Nice shot - handheld? Reminds me that I'd like to head back to Korea to get to see and photograph it properly (the last I was there was for a conference).
Do you ever use the self-timer? It raises the mirror before the shot so the only "slap" is after the image has been taken. I use it a lot, especially handheld for slower speeds, but sometimes also on a tripod. I think the FE may be the only (or one of the only) Nikon cameras that does this.
That said, I'm not against the fuzziness in this image at all.
(oh, and yeah, I think the mirror foam is one of the first things to disintegrate in these cameras - I've replaced the foam in all of my FE cameras).
