  • Universal Lens Filter - 3 Pack

    This Universal Lens Filter combo pack equips you with two 50mm filters and one 70mm filter, designed for safely photographing solar eclipses and sunspots with your existing camera or binoculars. Made with Thousand Oaks Density-5 SolarLite film, these filters meet the strict ISO 12312-2:2015 transmission standard by rejecting 99.999% of all incoming sunlight.

    Meets ISO 12312-2 Requirements: Safe Solar Viewing and Imaging

    The core of each filter is the renowned Thousand Oaks Density-5 SolarLite film, which meets the transmission and quality requirements of ISO 12312-2:2015 for direct observation of the Sun. Meeting this standard ensures that no harmful radiation will reach your camera sensor or your eyes when used correctly over the front of an optical instrument. These filters are designed exclusively as accessories for cameras, lenses, telescopes, or binoculars and must never be used as standalone eyewear.

    Foldable Design for 50mm and 70mm Lenses

    Constructed from double-layer heavy card stock, each filter folds into a secure, cup-like shape that fits snugly over the front of your optics. This pack includes two 50mm filters and one 70mm filter, covering the most common objective sizes for camera lenses and binoculars. The interior surface is black to reduce internal reflections and maximize image contrast.

    99.999% Rejection for Crisp, Orange-Tinted Views

    By blocking 99.999% of the Sun's energy, these filters reveal our star in a crisp, clear, and aesthetically pleasing orange tint. This level of filtration allows for the safe, detailed observation of large sunspot groups and the dramatic phases of a solar eclipse. The high-density film renders a sharp solar disk, free from the scattering or distortion common in lower-quality filters.

  • Is the Universal Lens Filter safe for looking directly at the sun?

    Yes, but only when placed over the front of a camera, binocular, or telescope. The filter material meets the ISO 12312-2:2015 transmission and quality requirements for direct solar viewing through an optical instrument. It is not designed to be used as handheld glasses or eyewear.

    How do I attach the Universal Lens Filter to my camera lens?

    The filter is made of foldable heavy card stock. You simply form it into a cup shape and slide it over the front of your camera lens, binocular objective, or small telescope. The fit should be snug to prevent it from falling off during use.

    Can I use the 70mm Universal Lens Filter on my 10x50 binoculars to see sunspots?

    No, for 10x50 binoculars, you would need two of the 50mm filters, one for each objective lens. The 70mm filter is too large. This pack conveniently includes two 50mm filters, making it suitable for most standard-sized binoculars.

    Which filter from the Universal Lens Filter pack should I use for a DSLR with a 70-300mm telephoto lens?

    Measure the outside diameter of the front of your lens barrel, not the filter thread. The 50mm filter fits outside diameters of 50mm to 69mm and the 70mm filter fits 65mm to 89mm.

    What color will the sun appear through the Universal Lens Filter?

    The sun will appear in a sharp, high-contrast, and natural-looking orange tint. This is characteristic of the high-quality Thousand Oaks SolarLite film used in the filter's construction.

    Why is the inside of the Universal Lens Filter black?

    The interior of the heavy card stock is black to absorb stray light and prevent unwanted internal reflections. This design feature helps improve the contrast of the final image, ensuring you see a sharp solar disk against a dark background.
