Canon EOS-5 repair & common faults
Excellent coverageThe EOS-5 was Canon's 1992 flagship enthusiast SLR, sold as the EOS A2/A2E in North America, and the first production camera with Eye Controlled Focus, letting the camera pick an AF point by tracking where in the viewfinder the photographer was looking. It pairs that with a fully electronic EF mount and a vertical-travel focal-plane shutter, so most faults trace back to eye control calibration, the shutter's electromagnetic release, or the power feeding both.

Common Canon EOS-5 faults
Canon EOS-5 Eye Control Focus not picking the right point
Eye Control needs a per-user calibration stored in the body, and on a camera this age that calibration can drift or the eyepiece sensor reading it can lose accuracy, so the camera locks onto the wrong AF point or refuses to track eye movement at all. Re-running the calibration is worth trying first, but a sensor that will not read a steady eye at all points to the assembly itself rather than a settings issue.
Canon EOS-5 won't fire the shutter
Every function on this body draws through the 2CR5, so a fresh cell is the first thing worth trying with a completely dead shutter. If power is good and it still won't trip, the fault sits with the electromagnetic release or the shutter's own drive electronics, and that is a bench job rather than something to chase further by hand.
Canon EOS-5 LCD panel fading or blank
The top-panel display on cameras of this generation is prone to losing segments or fading unevenly with age, usually down to the display itself or the contacts feeding it rather than anything electronic further back. A blank or patchy readout does not usually mean the camera has stopped metering or firing correctly underneath it.
Canon EOS-5 meter reading erratic or exposures inconsistent
Evaluative metering on this body runs through contacts at the lens mount as well as the internal sensor, so exposures that wander from frame to frame can point to either side of that chain. Trying a second EF lens is worth doing first, since a fault confined to one lens is a different job entirely to one that follows every lens fitted.
Canon EOS-5 dead, no response at all
A body that shows nothing, no LCD, no meter, no shutter, points to power delivery before anything else. The 2CR5 sits in a chamber where the contacts can lose tension or corrode over time, so a fresh cell seated firmly is worth confirming before assuming a fault further into the electronics.
Canon EOS-5 mirror stuck up
A mirror that lifts on firing and does not return is a familiar complaint on EOS bodies of this era, usually down to the foam damper in the mirror box perishing and gumming the mechanism rather than an electronic fault. It tends to worsen with continued use, so it is not something to keep firing through.
