The Solar ND100000 Eclipse Filter from K&F Concept is a high-density neutral density filter designed for safe solar and eclipse photography on lenses or filter holders with a 55 mm thread. Engineered to attenuate sunlight to levels suitable for imaging the solar disc and observing solar phenomena, the filter provides a uniform reduction of visible light while blocking harmful infrared and ultraviolet radiation. It attaches directly to compatible lenses or filter holders with a 55 mm screw thread and is intended for use with cameras and optical setups where secure, optical-grade solar attenuation is required.
Advantages
This eclipse filter offers very high attenuation, enabling safe imaging of the sun and bright solar features without damaging camera sensors or eyepieces. Its optical-density design produces a neutral, even darkening across the field to preserve contrast and detail on the solar disc. The 55 mm threaded mounting provides straightforward compatibility with lenses and filter holders that accept 55 mm filters, allowing stable attachment for photography or visual observation. The filter’s construction focuses on consistent light reduction and protection from non-visible radiation important for sensor safety and image fidelity.
Suitable for
- Photography of solar eclipses and partial solar events
- Solar disc imaging with DSLR, mirrorless cameras, or compact systems fitted with 55 mm adapters
- Attaching to telescopes or spotting scopes via 55 mm adapter rings or filter holders
- Field solar observation where a compact, screw-in solar filter is preferred

- Optical performance: uniform visible-light reduction with UV/IR blocking properties
- Compatibility: designed for lenses and filter holders that accept 55 mm threaded filters
How to use
Before attaching, confirm the lens or adapter accepts a 55 mm threaded filter. Mount the filter securely by screwing it onto the lens front or into a filter holder with a 55 mm thread until it is seated without cross-threading. When using with a camera, ensure the camera is on a stable tripod and frame the sun using live view or electronic viewfinder; never look through an optical viewfinder while pointing at the sun. Check that the filter is free of scratches, pinholes, or other damage before every use. Use proper exposure settings for solar photography, typically short shutter speeds and low ISO, and bracket exposures as needed to capture detail in different solar features.
Usage recommendations
For safe operation, always inspect the filter for any damage before use and avoid using the filter with optical viewfinders or without proper mounting. Use only with equipment that securely accepts a 55 mm screw-in filter and follow manufacturer guidance for your camera and lens to prevent light leaks. When photographing eclipses, practice framing and exposure beforehand and allow time for careful mounting and alignment on the day of the event.
