Konica FT-1 repair & common faults
Excellent coverageThe Konica FT-1 is an early 1980s 35mm SLR built on Konica's AR bayonet mount, distinguished by a motorised film advance built into the body itself rather than an add-on winder, running off four AA cells. It gives aperture-priority automatic exposure with manual override, and being electronically governed throughout, it depends more on clean power and sound wiring than the mechanical Konicas that came before it.

Common Konica FT-1 faults
Konica FT-1 motor drive won't advance the film
The built-in advance draws on four AA cells rather than a small button battery, and weak or old cells are the most common reason it turns over slowly or not at all. Worth trying a fresh set before assuming a fault. If it still won't run, or runs but the film doesn't move, that points to the motor or drive gearing itself, which is a mechanical wear item on a camera this age rather than anything electrical.
Konica FT-1 meter reads wrong or won't switch on
A dead or erratic meter on this model usually shares a cause with a sluggish advance, since both draw from the same battery compartment, so fresh AA cells are worth ruling out first. Beyond that, a meter that stays dead points to a broken switch or wiring fault, while one that's simply inaccurate suggests the metering cell has drifted with age, a wear issue rather than a quick fix.
Konica FT-1 shutter uneven or capping at fast speeds
Uneven exposure across the frame, worse at the fastest speeds and fine at slower ones, means the shutter's two curtains have stopped travelling in step, a fault known as capping. On a camera this old it's usually ageing lubricant or slightly stiff curtain tapes rather than the timing circuit itself, but either way it needs the mechanism opened up to confirm which, and it's a genuine fault rather than something to leave running.
Konica FT-1 viewfinder dim or hazy
A dim or hazy finder on a camera of this vintage is most often the mirror damping foam breaking down and shedding dust onto the mirror and focusing screen, or the mirror silvering starting to go underneath it. Less commonly the prism itself has clouded from the same foam decay migrating upward. Either way it's a foam and optics job rather than anything to do with the shutter or metering.
Konica FT-1 frames fogged or light leaking at the edges
Foam light seals around the back door and hinge on a camera this age have almost certainly gone sticky or crumbled away, and that's the near-certain cause of fogging along one edge of the negative or inconsistent leaks between frames. It's a straightforward foam replacement, not a sign of anything wrong with the shutter or metering, though the mirror box seals can fail on the same timescale and give a similar result.
