    • Visual and mechanical inspection: check body, mount, lens mount, seals, buttons, dials, compartment covers, and straps for wear or damage; inspect for corrosion or liquid intrusion.
    • Firmware and software: confirm firmware is current or update to the latest stable version; verify compatibility between camera body and lens firmware.
    • Sensor and shutter checks: inspect sensor surface for contamination; test shutter curtain timing and cycles; measure shutter accuracy across speeds.
    • Light metering and exposure calibration: verify meter accuracy, TTL metering behavior, and exposure consistency across modes and ISO settings; adjust calibration offsets if within service scope.
    • Autofocus (AF) testing and calibration: run AF target tests (static and contrast targets), check AF module performance across focus points, and perform micro-adjustments or full AF module alignment for both single-lens reflex and mirrorless systems.
    • Image stabilization (VR/IBIS) testing: check operation and effectiveness of VR (Vibration Reduction) or IBIS (In-Body Image Stabilization) systems and adjust/repair actuators or sensors as needed.
    • Lens optical checks: test resolution, contrast, chromatic aberration, vignetting, decentering, and focus shift; perform collimation, helicoid adjustments, and optical element alignment.
    • Mechanical adjustments and part replacements: replace worn shutters, diaphragms, focus helicoids, bayonet mounts, or cavity seals; realign mounts and mechanical couplings.
    • Final verification and test imaging: shoot standardized test charts and real-world scenes at multiple apertures, focal lengths, and shutter speeds; inspect RAW/JPEG output for consistent exposure, color rendering, sharpness, and absence of artifacts.
    • Documentation and reporting: create a service report listing procedures performed, parts replaced, and test results; often includes before/after measurements or sample images.
