An extension tube, which is installed between lens and camera, is used to adjust focal distance. Different
combinations of the 7 tubes can be used to achieve any desired thickness.

• Do not overlap 2 or more extension tubes (0.5 mm, 1.0 mm, 2.0 mm). Since they are installed between the lens and the
threaded section of another extension tube, overlapping them will cause unstable fixation.
• When using an extension tube larger than 30 mm, reinforcement is necessary to avoid being affected by vibration.
• When using the extension tube, please test in the your actual environment before using.
