FAQ
- Why is the lens autofocus not clear?

There are many reasons why the lens autofocus is not clear; the main reasons are as follows which can be checked one by one:

1. During the focusing process, if there is a large moving target in the lens screen (occupying more than 1/3 of the picture), just refocus;

2. If the lens is used for a long time, and the gear, CAM and other transmission parts wear and tear, resulting in unclear focus, adjust the module or control board parameters to make the focus clear again;

3. For hardware problems such as the potentiometer not working, replace the hardware that does not work.

- Why can not the lens control board or module connect to the computer?

There are many reasons why the lens control board and the computer cannot be connected; the main reasons are as follows which can be checked one by one:

1. Replace the USB port, which may be incompatible with the data cable;

2. Replace the data cable, which may be incompatible with the computer or of the wrong type;

3. Check if the wiring of the module or the control board is loose;

4. For module or control board hardware problems, replace the hardware.
