Smooth flight! Keep up the good work! Interesting theory about the camera sharpness causing the blurring/artifacts. Would love to hear if reducing it helps a bit.
Looks like yet another case of the "calibration problem." Seconds after arming, the RSSI and bitrate drop by a half. This is affecting so many VTXs now.
I am using this servo and cutting the foam out to slide the servo in and then mounting the camera directly to the servo. www.electromaker.io/shop/product/9g-270-metal-servo-with-analog-feedback-15kg
