Caution :

*When shooting with the built-in filter, the reflector will be lifted and the OVF will not be able to view the scene.

*Due to the difference in focus system design among manufacturers, some entry-level models may not be able to focus smoothly when using OVF, so it is recommended to use Live View mode.

*Do not shoot directly at the source of bright light, as the interference filter’s nearly 100 layers are prone to secondary reflection, which can degrade image quality.

*When removing the built-in filter, lay the camera body flat facing upward so that the filter does not touch the end of the lens.

*L-Pro UT filter thickness is only 0.3mm, and will not break if used correctly, but do not use any violent means.
