Review: Great item - especially for the price - I've been very impressed with this item for the past 2ish years. It's been a durable design at a very affordable price. It fulfills everything that it said it would and is easy to install and use. My images are still very clear and not cloudy as I use the filter. It makes a huge difference in my image using this filter to help reduce the harsh light coming into my camera. There is a slight vignette on the image, but not drastically noticeable. The only downside is the lack of gauges to keep track of what stop the filter is at. It requires you to watch the LCD screen as you turn the knob on the filter. Still happy with the product, but wish there were numbers on the filter. Overall, highly recommend, especially for the price!
Review: high value for the money. - Phenomenal value for the quality you're getting. The function feels high quality at a low price point. easy to put on and off and comes in handy for all kinds of scenarios.

## Features

- 【Import Optical Glass】Crafted from premium AGC optical glass with 8 multi-layer coatings, this ND filter reduces reflections and glare, ensuring superior image quality.
- 【Versatile Light Control】With 1 to 9 stops of adjustable light reduction and 360-degree rotation for precise dimming settings, this filter is perfect for diverse scenarios. (Note: Max stops may cause a cross-pattern effect, commonly known as an "X black cross." This phenomenon is natural and temporary, occurring due to the adjustable ND filter's interaction with specific lenses and focal lengths.
- 【Glare-Free Surface】Treated with an oxidized sandblasting process, this filter prevents unwanted stray light and minimizes unnecessary reflections on the metal surface.
- 【Slim and Secure】At a mere 7.4mm thickness, the CNC-patterned design ensures enhanced friction while rotating, making it easy to attach/detach lenses and accessories anytime, anywhere.
- 【Compatibility Note】This ND filter suits all 77mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. Additionally, a 82mm lens cap is required for this 77mm variable ND filter.

### ⭐⭐⭐⭐⭐ Excellent Quality ND Filter for Professional Results
*by R***! on October 28, 2024*

This ND filter is a fantastic addition to my photography gear! Made from high-quality AGC optical glass with 8 multi-layer coatings, it really reduces reflections and glare, resulting in crystal-clear images. The 1-9 stop light adjustment is incredibly versatile, perfect for everything from bright daylight shots to more controlled, low-light scenes. The 360-degree rotation offers precise control over the light reduction, although, at the highest stops, I did notice a faint cross-pattern ("X" effect), which is typical for adjustable ND filters on some lenses. The filter itself is sleek and slim, just 7.4mm thick, and the CNC-patterned edge provides great grip, making it super easy to attach or adjust quickly. I love the anti-glare finish, which minimizes stray reflections, especially in challenging lighting. One thing to note: you’ll need a 55mm lens cap for this 52mm filter, but that’s easy to work around. Overall, it’s an impressive ND filter with outstanding performance and durability. Highly recommend it to anyone looking to improve their outdoor and landscape photography!
