功能

• A round reflective variable ND filter (VND/VND-U) is fixed to the rotary holder.
• The weak part of the glass is protected by metal, so it can be used safely.
• The position of the adjusted filter can be clamped.
• The filter can be turned 360 degrees without interruption.
• The NDHN-U has a variable ND filter (VND-U) built in for external use.
• * Please contact us if you want to replace the variable ND filter.
• * Since the filter is very fragile and special tools are required for removal and installation, the replacement work will be carried out by the company.
