The Formatt Hitech 37mm Firecrest Neutral Density 5.4 Solar Eclipse Filter produces images with a neutral color tone and no color-cast or loss of sharpness. Its 18-stop exposure reduction, built-in infrared cut, and 5.4 density blocks radiation outside the visual spectrum that imaging sensors are able to detect, which can cause interference with capturing clear images, and creates a darkening of the entire image that makes it effective for solar and solar eclipse photography. With this filter, users can capture photographs with a wider aperture or slower shutter speed than normally required. This is strictly a photographic filter and is not suitable for direct solar viewing with the naked eye.
Warning; under no circumstances should these filters be used to view a solar eclipse with the naked eye. These products are strictly for on-camera use. These filters do not offer the same level of optical protection as solar eclipse viewing glasses and using these to look directly at the sun before, during or after a solar eclipse could permanently damage your eyesight.
Formatt-Hitech will not be held liable for any costs, associated expenses or medical claims relating to damage to your eyesight as a result of improper use of these filters.
Due to the extremely long exposure times these filters make possible, the risk of light leaking in through the camera body and manifesting in your shot is high. We recommend that you take steps to mask the eyepieces/viewfinders and and ports to prevent this from happening. Many photographers use a low adhesive black tape for this purpose however it is your responsibility to ensure that anything you affix to your camera will not cause damage to the camera body or functionality. Another option is wrapping the camera in a thick black cloth although you should leave some areas of the body exposed to dissipate heat.
Even with the extreme density of these filters, we recommend you contact your camera manufacturer to assess the suitability of your camera for shooting directly into the sun. Formatt-Hitech will not be held liable for any damage caused by continued exposure of your camera sensor to direct sunlight with or without our filters in place.
