Quality Ratio – Calibration Check

(See Chart Features for general chart features - changing scales, copying to clipboard etc)

The Quality Ratio chart shows the difference in quality between the Live View and non-Live View (phase detect) measurements at each point.

A value below 100% shows that contrast detect quality is better, above 100% shows that phase detect quality is better.

Key:

• Orange line: Quality Ratio measurements
• Green area: lens does not require calibration
• Blue area: lens is performing well, but may benefit from checking
• Red area: lens requires calibration

Interpretation

A well calibrated lens should show most points within the blue or green area.
