To install a BTSensor lens
Note: Only used on s250e and Slim 13E sensors.
- Screw the lens onto the BTSensor with the included plastic lens tensioner between the M12 lens adapter and the lens itself. Tighten until proper focus is achieved.
- Once you achieve the desired focus, hold the lens in place while you tighten down the lens tensioner.
Note: The s250e comes with a spring for the lens instead of a tensioner. No tightening is required for this lens.
