Inspecting Focus Compensation helps Troubleshoot AF Problems

⚠️ Viewing Focus Commpensation is NOT a test of Focus Compensation accuracy!
This menu helps you check if the Focus Compensation in the lens is working properly without Disassembly.
- Focus Compensation allows the camera to adjust focus more accurately based on the specific lens you're using.
As you slowly turn the focus and zoom rings, the display should show smooth changes in values. If the values don’t change, or if they jump suddenly, there might be a problem—like a damaged internal part (called a wiper) or a corrupted memory chip in the lens.
This tool is useful when you're having Auto Focus (AF) issues.
