I've been using the same Nikon FE for over 20 years. If I'm shooting by available light, there is always enough light to see the meter to get some idea of where it is. If it's that dark, I'm not hand holding, the camera is on a tripod. Either set it to A and go, or manually set the exposure as you think it should be.

Really with all the cameras I've ever had, I've NEVER used the in finder illumination. In fact, my FM that I just picked up a couple years ago is much more intrusive with the LED's blazing away in the dark!

Just my $0.02, which adjusted for inflation would be about -$36.84
