Good... but it could be more user friendly

This is part of a good filter system. I didn't give it 5 stars because I hate the fact that they don't print the number of f-stops it reduces right on the filter. How hard would it be to do that?

Great magnetic filters for Landscape Photography. No weird color shift. Use often.

Become a master of light manipulation in your photography with the 77mm Nano-X Neutral Density ND8 0.9 3-Stop Magnetic Filter. Designed for precision and ease of use, this high-quality filter offers rapid installation and removal thanks to its innovative magnetic design, allowing you to adapt to changing light conditions in the blink of an eye.

Crafted with 16 layers of advanced nano-coating, this filter boasts exceptional anti-reflective properties, including a special green film that effectively reduces surface reflections while filtering out ultraviolet rays. The result is a significant improvement in light transmittance, ensuring that your images exhibit balanced colors without any unwanted color cast.

The neutral density of 0.9 (3-stop) is particularly effective for photographers looking to achieve a shallower depth of field or to capture movement with a slower shutter speed, without overexposing the shot. Whether you're shooting portraits with a dreamy blurred background or dynamic landscapes, this filter provides the creative control you need.

Durability is also a key feature of this versatile filter. The optically polished glass is treated with a high-tech film that renders it moldproof, waterproof, scratch-resistant, and resistant to grease. This means that even if the filter becomes contaminated with water droplets or oil, it can be easily cleaned without affecting image quality.

The filter is complemented by an aerospace-grade aluminum alloy magnetic lens cover, which is both magnetic and threaded for a secure fit. This two-in-one functionality ensures that your lens is always protected, whether the filter is in use or not.

Enhance your photographic toolkit with the 77mm Nano-X Neutral Density ND8 0.9 3-Stop Magnetic Filter, and experience the benefits of a durable, effective, and easy-to-use solution for controlling light in your images.
