Because the Entaniya Fisheye HAL series is a fisheye lens, standard matte boxes and filters cannot be used.
To use ND filters, use the ND pocket on the bottom part of the lens.
How to use ND filters with the Entaniya Fisheye HAL Series
See the video above for instructions on how to remove the cap on the bottom part of the lens and install the ND filter.
*The glass filter in the cap section is not fixed, so be sure to place the lens on a stand when removing the bottom cap.
