$102 K&F Concept 100x100mm Square ND1000 Filter Kit
10-stop ND1000 kit with holder and 8 adapter rings
This K&F Concept magnetic kit for DJI Osmo Pocket 3 brings together four filters designed for outdoor video and photography: a CPL to reduce reflections and three fixed neutral densities ND16, ND64 and ND256 to maintain a more controlled exposure in different light conditions. The magnetic mounting system makes it quick to change the filter on the fly and the ultra-slim design is designed not to interfere with the closure of the gimbal.
Construction combines high-definition AGC optical glass with aluminum alloy frame. According to the product sheet, each piece incorporates multi-layer coatings on both sides to repel water, dust and grease, in addition to improving scratch resistance. In practice, this makes it a compact and reasonable kit for those who want to add contrast control with the CPL and light reduction steps equivalent to 4, 6 and 8 stops with the included NDs.
It's an especially useful option for creators who shoot travel, city walks, vlogs, and outdoor scenes with the Pocket 3 and need to maintain more cinematic shutter speeds without overly complicating their workflow. It's also handy for shots over water, glass, or shiny surfaces, where CPL helps clean up reflections and recover color.
