I am using an Auto Focus IMX582 camera with a sensor resolution of 5312x6000. The problem I am facing is that it takes too long to focus and return the lens value. Additionally, I have six PoE cameras connected. When I switch the sensor to 4K, which is the default resolution, the focusing of all six cameras is quick. I use the focus value for fixed focus to capture images at three different exposures for HDR merging.
