Hasselblad 500 repair & common faults
Excellent coverageThe Hasselblad 500 series (500C, 500C/M, 501C and kin) is the classic modular medium format SLR, built from the late 1950s and produced for decades with only incremental changes. The body carries no shutter of its own, each lens has its own leaf shutter, and the body's own auxiliary shutter and dark slide interlock exist purely to protect the film during a lens or back change. It is fully mechanical, no battery required to fire.

Common Hasselblad 500 faults
Hasselblad 500 capping, dark band across negatives
A band of underexposure across part of the frame, usually worse at faster speeds, is the classic Hasselblad symptom called capping. It means the body's auxiliary shutter and the lens's own leaf shutter have drifted out of sync, so the film is briefly shielded mid exposure. It points to wear in the linkage timing rather than a dead lens, and is common on well used bodies.
Hasselblad 500 won't fire
This body will only release if the winding crank has fully cocked the shutter and mirror together, the lens is properly seated and locked, and the film back's dark slide is withdrawn, it is an interlock by design, not a fault, in most cases. If all three check out and it still won't fire, the fault sits in the cocking or interlock linkage itself. Worth confirming the dark slide is out before assuming a mechanical failure.
Hasselblad 500 shutter sticking on slow speeds
Hesitation or an overlong exposure only at the slower marked speeds points to the delay escapement inside the lens's own leaf shutter, the part that governs timing at the low end. Old lubricant thickening with age is the usual cause, and it tends to worsen gradually rather than fail outright. Faster speeds working normally is a useful sign that the fault is confined to that mechanism.
Hasselblad 500 mirror stuck up
A mirror that stays up after firing instead of dropping back down points to the mirror return mechanism, which is mechanically linked to the winding and cocking cycle rather than sprung independently in the usual SLR sense. It is a known wear point on bodies with heavy use over the decades. It does not on its own mean the shutter or lens is affected.
Hasselblad 500 film back light leaks
Fogging or a light streak at the edge of frames from an A12 or similar magazine usually comes down to the foam light seals inside the back, which compress and crumble with age regardless of how the camera itself has been used. Confirming the dark slide is fully seated is worth doing first, since a slide left slightly proud will do the same thing. Anything beyond that is a magazine service matter.
