Important Notes

• Due to different manufacturing tolerances of various brand M39 cameras and lenses, the sealing tightness may have slight differences, which will not affect normal use.
• Align the screw thread gently when installing to avoid cross-thread scratching the aluminum thread surface.
• For long-term humid storage, place desiccant together with camera and lens to enhance anti-mold effect.
• Wipe the cap surface with dry soft cloth only, do not use corrosive cleaning liquid to avoid damaging the anodized coating.
