Restores your Full Spectrum camera to a regular color camera. 58 mm (Canon) or 52mm (NIKON)filter screws directly onto your lens. Corrects the full spectrum effect and allows you to use your DSLR as a normal camera without UV and IR coloring.

52 or 58mm Hot Mirror Filter

  • This is a high quality polished optical glass filter from Kolari Vision. Size 58mm has standard front and back threads.

    Also known as a lowpass filter or UV/IR cut filter, this filter blocks UV and visible light, and allows a full spectrum converted camera to take normal pictures. Pair it with a two spectrum converted camera for the best color rendition.

    This is the first filter designed specifically for use with a full spectrum or two spectrum converted camera and was designed with a similar transmission of the hotmirror filters that cameras normally employ. Because of its design, it allows for normal use of the camera with all of the regular white balance presets still working. You will notice the color of this filter is blue, unlike other hotmirror filters that are clear. This is a good thing, the original lowpass filters found in cameras are this same shade of blue, this is a visual confirmation that the filter is blocking the same wavelengths.

    A note about wide angle: Unlike the B+W 486 filter (a popular hotmirror filter), this filter does not block light by interference, but instead uses absorbtion. This means that regardless of the angle of incidence, the color will not change. The B+W 486 will cause color changes on wide angles around the edges, ours will not.

    The filter requires no exposure compensation.

    Not all camera lowpass filters have the same transmission. Ours is designed with aggressive IR blockage to eliminate IR leak on all camera models. Consequently, it also has more UV transmission than many cameras, for outdoor uses it is best to pair it with a UV filter, or even better, use it over our two spectrum conversion. See bottom of page for transmission curves.

    For best results, this can be paired with our two spectrum conversion to filter out as much UV light that most current camera lowpass filters.
