Camera should be set to forced flash even if you intend to use it off camera since the Godox system does not require to place the body in the WL position -

Problem Description – Sony ZV-E10 II A few weeks ago, I purchased my Sony ZV-E10 II camera from Digital Photo Supply. The unit is updated to the latest available firmware and is showing an abnormal behavior in the continuous autofocus system (AF-C), which can be consistently reproduced under different conditions and with various native Sony lenses. Observed Symptoms The parameters for focus transition speed (AF Transition Speed) and subject shift sensitivity (AF Subject Shift Sensitivity) do not remain stable. When the camera encounters a point or surface with low texture or contrast and takes time to focus, instead of maintaining smooth “focus breathing” according to the settings, it makes a sudden jump to focus. From that moment, autofocus behaves as if the speed were set to the highest value, completely ignoring the configured settings. After a few seconds, or when reframing, the system resumes normal operation. This phenomenon occurs even with Active Stabilization, Face/Eye AF, and Touch Tracking turned off. Testing Methodology Tests were conducted under various lighting conditions, both high-contrast and flat light. Different subjects were positioned at varying depth distances but laterally aligned (scenarios with partially overlapping elements). Medium and low focus transition speeds and medium or low subject sensitivity settings were used—these are the cinematic parameters I normally work with. All tests were performed exclusively with native Sony lenses, varying light and contrast levels to check behavioral consistency. Under these conditions, the camera consistently showed instances where, when using Spot Focus (S/M/L), it would momentarily lose focus and, upon regaining it, start focusing instantly on any new subject as the camera moved—completely ignoring the configured transition speeds. Control Camera Used A Sony ZV-E10 (Mark I) was used as a reference with identical lenses, settings, subjects, and lighting conditions. It passed all tests successfully without reproducing the issue. Impact on Professional Use This malfunction is catastrophic for my professional video work, where precise and fluid focus transitions are critical. When the system ignores transition speed and sensitivity settings, the footage becomes unusable, directly affecting visual continuity and cinematic quality. If this behavior cannot be corrected, the camera is unsuitable for professional video use, as it compromises focus system stability and predictability.
