【Enchanting Spiral Halo Effect】 This prism effect filter frames your shots with a circular halo, keeping the image clear at the center stage while transitioning the background into a swirling, magnified blur, intensifying the mood and atmosphere without further post editing | 【Rotate to Adjust】 Adjust the halo effect by rotating the filter 360° making it more compact and concentrated to more loose and expansive. Avoid shooting directly into bright light or the sun to prevent potential damage to CMOS sensors, lens iris, and other components caused by high temperatures. | 【Highly Transparency】 Made of solid K9 optical glass and transmits light with high resolution, thus preserving the quality and accuracy of the images even with the halo effect | 【Ultra Slim Frame & Smooth Rotation】 The ultra slim yet sturdy aluminium alloy frame with the advanced CNC precision treatment enables effortless installation, and patterned knurls ensure precise rotation for achieving the best effects | 【Package Contents】 1x 58mm Spiral Halo Prism Filter, 1x Cleaning Cloth, 1x Filter Pouch. Note that this filter is compatible with 58mm lenses. You can connect with an adapter ring to match your lens. Please verify the thread sizes before purchase.
