It's perfect for capturing landscapes like stunning rivers, breathtaking waterfalls, and captivating light trails with a smooth, soft look. 【Precisely Placed Hard Stops】Equipped with hard stops at both ends of the VND filter, ranging from 1 to 8.6 stops (approximately ND2-ND400), allowing you to dial to the precisely marked stops to achieve the exact ND level needed for perfect exposure shots. Note: The mechanism of variable ND filters is based on the principle of polarization. When using the maximum aperture, an X black cross may occur due to the interaction between the VND filter and certain lenses and focal lengths. 【Faithful and Vivid Color Reproduction】The ND filter achieves a true color effect, reproducing faithful colors. You can spend more time creating your work rather than color correcting in post-processing. 【Lightweight Aluminum Frame】The tightly sealed filter with an ultra-thin aluminum alloy frame easily achieves the desired effect. The CNC precision-machined knurled ring ensures a secure grip, making it easy to install and remove the filter. 【Multi-Coated Premium HD Optical Glass】The multi-layer coating allows the high-definition optical glass of the filter to capture vivid colors and manage contrast without losing image sharpness. Furthermore, it protects against water, dust, oil, fingerprints, and scratches, allowing for peace of mind and maintenance in various environments and conditions.
