In recent years, the usage rate of square filters has been increasing in single-lens reflex cameras and mirrorless cameras. In the scenes such as long exposure work with ND filter and shooting with a difference in brightness on the screen such as sunset/morning sun with half ND filter, it has gained support by street photographers.

Zhuhai-based optical equipment and lens manufacturer NiSi Filters has released a square holder/filter kit for the popular Ricoh GR III high-end digital cameras. This product is a part of the square holder series dedicated to compact cameras following the SONY RX100VII dedicated model released this June. A lineup of 3 types has been added to the smartphone-only “P1 Prosories”.

This holder was designed to make it easy to enjoy filter without compromising compactness even on high-end compact cameras. You can easily use the effects of optical filters such as ND filters and PL filters, as well as square filters of GND filters, with high-end compact cameras.
Although this product is low cost and compact, it uses the same lightweight and durable resin and aluminum as other NiSi high-end products.
