… The camera has a 1/2.5 sensor. (This one: https://a.co/d/cbE0qu4 ) Is that a small sensor? . This might help you put that into perspective, Jackie https://en.wikipedia.org/wiki/Image_sensor_format#/media/File:SensorSizes.svg The history of sensor-sizing is rather ‘weird & wonderful’ ! MichaelG.

I saw a video by Carl H which was extremely helpful in understanding the mechanism for the phase turret. I have a different model but it functions very similarly: https://youtu.be/QSjlgNyfwJw?si=...
