You are then asked to double check the main body and lens selection before proceeding. This is because the resulting calibration is stored relative to these choices in the calibration database. Additionally it is because the lens must be calibrated for this process to work well, therefore it is important we make sure we are using the right calibration before proceeding

Now, make sure that the lens is set to the Golden Point (Focus = 0.5 and Zoom = 0.0). This is to ensure that the most accurate part of the lens calibration is used while doing the Live Update.
