The NiSi IP-A Filter Holder for iPhone adds filters to your iPhone via a quick and easy bayonet mount. Specifically designed for the iPhone, this filter holder secures to the front, back, and top of your phone. Stack up to three circular NiSi IP-A filters, available separately. This mount is designed to operate with no vignette when using 0.5x camera mode and two circular IP-A filters. The holder is compatible with NiSi IP-A circular filters and the NiSi P2 square filter holder, both available separately.

Designed for the IP-A Filter Holder for iPhone, the P2 Square Filter Holder from NiSi allows P1 square filters to be used on an iPhone. Two square filters can be stacked together and rotated 360°, which helps create unique effects. This holder mounts using a bayonet mount and does vignette when using your iPhone's Ultra Wide (0.5x) camera.

Part of the P1 filter system, the P1 Prosories HD Polarizer Filter for Smartphones & Compact Cameras from NiSi fits into the P1 holder (not included) that attaches over a smartphone's lenses or a compact camera's lens. When inserted, this particular filter uses Nitto polarizing film to increase image and video saturation while simultaneously reducing reflections and glare from non-metallic surfaces, such as water, glass, or snow.

Part of the P1 filter system, the P1 Prosories GND8 Filter for Smartphones & Compact Cameras from NiSi fits into the P1 holder (not included) that attaches over a smartphone's lenses or a compact camera's lens. Unlike an ND filter that evenly reduces all light, this graduated neutral density (GND) filter reduces only a portion of the light from entering the camera. When inserted into the holder, the darker section reduces light by 3 stops. This is ideal for situations with a more definitive horizon line or separations in the composition where objects protrude into the skyline, such as mountains, trees, and buildings. In these bright areas where light is reduced, exposure is evened out with the remainder of the image.

Designed for mobile phones and compact camera systems, the P1 Prosories ND64 Filter from NiSi provides a 6-stop reduction in exposure, which allows the use of wider aperture settings for shallow depth of field, or slower shutter speeds for motion blur. This filter is built using high-quality glass with a nano coating that helps to prevent the loss of details. Also featured is a double-sided and multi-layered coating, water and oil resistance, and low reflectivity. This filter will not alter the color of your images.

Please note that to attach this filter to your device, you will need the NiSi P1 Prosories Mobile Phone Filter Kit.

Built with a hard exterior shell and lined with a soft microfiber interior, the P1 Prosories Case from NiSi has been designed to store and protect the P1 Mobile Phone Filter System. It holds the P1 Holder with a clip and up to four filters. Weighing only 1.2 ounces, this case is also small enough to conveniently store in your pocket and take with you on the go.
