Based on common issues specific to the Canon Autoboy 2, we performed comprehensive checks:

• Electronics/Power On: This model can suffer from power issues due to corroded battery contacts or internal motor failure. We tested power with known good batteries and confirmed stable operation. The camera powers on and functions correctly, with no signs of sudden death or overheating. (TESTED: OK)
• Shutter Functionality: The shutter can become stuck. We thoroughly tested the shutter mechanism by firing without film under various light conditions and confirmed accurate opening and closing of the shutter blades. (TESTED: OK)
• Film Advance: Film advance failures or stuck counters can occur, sometimes with a "buzzing" sound. We confirm the camera operates properly, implying correct film advance and counter movement during testing. (TESTED: OK - implicitly covered by "Work properly")
• Autofocus System: Issues with autofocus can lead to blurry images. We confirmed the lens visibly adjusts focus and the focus indicator changes correctly on subjects at various distances. (TESTED: OK)
• LCD Display (Quartz Date models): The date LCD on QD versions may show "black bleed." This camera is not a Quartz Date model, or this issue was not present during our inspection. (NOT APPLICABLE/NO ISSUE)

The noted optical flaws (slight haze, slight fungus, faint viewfinder haze) are distinct from these common functional issues and have been thoroughly disclosed in the "Detailed Inspection Results" section.
