Solar Filter K&F Concept ND100000 for Eclipse Photography, fits 52 mm lenses

Solar Filter K&F Concept ND100000 for Eclipse Photography fits lenses with a 52 mm thread and is intended for safe imaging of the Sun and solar phenomena. The filter provides very high neutral density attenuation (ND100000) to reduce incoming light to a level suitable for camera sensors and optical systems, enabling correct exposure when photographing eclipses, sunspots, or other bright solar details with compatible 52 mm lenses or adapters.

Advantages

The filter delivers extreme light reduction in a compact screw-in form factor compatible with lenses that have a 52 mm front thread. It is constructed to maintain image quality while protecting the camera sensor and internal optics from excessive light and heat during direct solar observation and photography. Its neutral density characteristic ensures minimal color cast and preserves contrast for accurate solar detail capture.

Suitable for

• Photographing solar eclipses with 52 mm threaded lenses or adapters
• Imaging sunspots and solar disk features
• Astrophotography setups requiring a solar-safe attenuation solution
• Visual solar observation through compatible optical systems when mounted correctly

Key specifications

• Filter type: Neutral density solar filter with very high attenuation (ND100000)
• Mounting: Screw-in design for lenses with 52 mm front thread
• Optical effect: Strong reduction of visible and infrared light for safe solar imaging
• Construction: Thin, flat filter element designed to minimize image degradation

How to use

Attach the filter securely to a lens with a 52 mm front thread before pointing the camera at the Sun. Confirm the filter is clean, undamaged, and seated evenly on the lens thread. Compose and focus the scene with the filter in place; use live-view or electronic viewfinder rather than the optical viewfinder to avoid eye exposure. Adjust exposure settings (shutter speed, aperture, ISO) as required for proper solar exposure while monitoring histogram and highlight clipping indicators.

Usage recommendations

Only use this filter for direct solar imaging when fully intact and correctly mounted on a compatible 52 mm lens or adapter. Do not look through an optical viewfinder when the filter is not securely fitted. Inspect the filter for scratches, pinholes, or delamination before each use; discontinue use if any damage is present. For prolonged sessions, periodically check the filter and camera for excessive heat. Follow all safety guidelines for solar observation and photography.
