Canon Canonet 28 Leatherette Replacement Tutorial

This comprehensive repair manual addresses the most common failure in the Canon Canonet 28: a light metering cell that no longer responds during automatic exposure mode. The guide pinpoints the underlying cause—oxidation accumulating on the two contact strips that supply power to the meter circuit when the aperture ring is set to A (automatic). The tutorial walks you through complete camera disassembly, including removal of the top plate, rewind knob, and base plate, with careful identification of each fastener and component to protect during the process. You'll learn how to verify the fault using a tweezers test and master the cleaning technique for the contact strips using fine files or 500-grit sandpaper, working methodically until the galvanometer needle begins responding again. The manual also includes full specifications for the Canonet 28 (shutter speeds, aperture range, ISO latitude, weight) and practical surface cleaning guidance. This workshop manual is invaluable for film photographers restoring this classic compact rangefinder to reliable working condition.
