FE: Mirror won't return when battery is low, and somehow new batteries were always appeared run down in no time at all.. When on a power supply, the camera would function fine. When I wanted to replace it with a second hand FE2, the one I handled in the store had the same problem. The guy in the store put new batteries in, it works fine for a couple of shots, then the mirror sticks. I have to conclude that the circuit design is marginal at best.
It's not a circuit design issue, it's mechanical. The circuit design is what it is... state of the art as the art was in that era. It relies 100% on a battery. Without a battery it doesn't work and the mirror stuck up is the mode the camera goes into without power. The FE, when not in prime cleanliness/lubrication condition MECHANICALLY jams too, causing the mirror and film advance to stick. Unjamming isn't too tough but requires removal of bottom plate and knowing which piece needs a little leverage. Other than that, the FE is a great little camera!
