Mobile ND filter for P1 system

The NiSi 3-Stop ND Glass Filter .9 slides into the P1 Prosories phone filter holder and cuts light by three stops, letting smartphone photographers use slower shutter speeds or wider apertures in bright conditions. It is built for creators who want long-exposure or shallow-depth-of-field effects without leaving the phone ecosystem.

Optical glass over resin

The filter uses optical glass rather than resin or plastic, which the maker says gives better clarity and durability. That material choice reduces the risk of colour casts or scratches that can degrade image quality during repeated outdoor use.

Slide-in mount for daily carry

The slide-in design locks the filter securely inside the P1 holder so it will not shift when the phone moves. The slim glass profile keeps the stack thin enough to stay in a pocket or small pouch, making it practical for everyday mobile shooting.

Questions about this item

Does the optical glass in the Nisi 3-Stop ND Filter .9 need any special cleaning or replacement over time?

The filter uses superior optical glass for clarity and durability; clean it with standard lens-care tools and replace only if the glass becomes scratched or damaged.

What exposure limit appears first when using the 3-stop ND filter for long smartphone exposures?

The filter reduces light by three stops, so the practical limit is the phone's maximum shutter speed or ISO floor before highlights clip.

Does the glass filter add noticeable heat or battery drain during all-day shooting?

The passive glass element generates no heat and draws no power; any warmth or battery use comes from the phone itself.
