Urth Solar ND100000 (16.6 Stop) Filter Plus+ - 67mm

Yes, this ND100000 (16.6 stop) filter is specifically designed to reduce light so drastically that it is safe to photograph the sun directly with a camera. However, never look at the sun directly through the camera's viewfinder without the filter attached or if the filter is damaged.

While technically possible, this filter's extreme light reduction (16.6 stops) is usually unnecessary and impractical for general landscape photography. It is intended for specialized uses like solar photography and extreme long exposures in very bright light.

Use a clean microfiber lens cloth. For tougher spots, use a small amount of lens cleaning solution or distilled water on the cloth. Always wipe gently from the center outwards. Avoid using paper towels or rough cloths that can scratch the glass.

16.6 f-stops means the filter reduces the amount of light reaching your camera sensor by a factor of 100,000. This is an extremely significant reduction, allowing for photography in conditions that would otherwise be far too bright.

The CoraNano coating and quality Schott glass are designed to minimize color casts and maintain color neutrality. You should experience true-to-life colors, especially when shooting in RAW format.

The 'Plus+' designation typically indicates enhanced features, such as a more advanced multi-coating (like the 20-layer CoraNano), a slimmer rim design, or superior glass quality compared to previous or standard models.

While possible, stacking filters can increase the risk of vignetting and reduce image quality due to increased light interference. Given the extreme density of this filter, stacking is generally not recommended or necessary for its intended use.

Switch to manual focus mode. Use your camera's focus peaking or zoom assist features to achieve sharp focus, as the extreme darkness can hinder autofocus performance.

Double-check that the filter is fully screwed onto the lens and that no light is leaking around the edges. Ensure your camera's ISO is set to its lowest native setting.

Verify that you are using the correct filter size for your lens. The ultra-slim rim design minimizes this, but on some ultra-wide lenses, slight vignetting might still occur at the extreme edges. Ensure the filter is not obstructed by lens hoods or other accessories.

Grip the filter firmly by its metal rim and gently twist it counter-clockwise. If it's stuck, try using a rubber grip or strap wrench carefully to avoid damaging the filter or lens.
