The two ND filters are used to reduce exposure light to improve photo quality when shooting the sun or over-bright objects. The sun will appear in a natural orange color when shooting through your DWARF II using these filters.

Attention: To install the UHC/ND filters on DWARF II, you need to use DWARFLAB's magnetic filter adapter. When shooting the sun, you need to install two ND filters for the two cameras in DWARF II, or it may damage the sensor of DWARF II.
