Iridium Clip-in Filter For Sigma FP/BF L-Mount – Magnetic

Unlock vibrant color and stunning infrared effects straight out of the camera with the Kolari Iridium Filter. Designed for both standard and full-spectrum converted mirrorless cameras, the Iridium Filter enhances image quality by selectively filtering out “in-between” wavelengths of light, letting pure reds, greens, and blues shine through with exceptional clarity. On standard cameras, this innovative filter produces images with richer saturation, deeper skies, warmer skin tones, and more vibrant landscapes with no editing required. On full-spectrum, the Iridium Filter delivers surreal, infrared-inspired imagery similar to the classic “Wood Effect” achieved with a 720nm filter, but with no channel swap required. Crafted with the premium optical glass we’re known for, our Kolari Magnetic Clip-In Filters for Sigma FP/BF (L-Mount) are finished with advanced anti-reflective and anti-smudge hard coatings to boost light transmission and reduce flares and ghosting. These multi-coated filters are also hydrophobic, dust-resistant, and scratch-resistant, making them easy to clean and built to withstand the demands of any shooting environment. Each filter is housed in a precision CNC-machined aluminum magnetic frame designed for maximum lens compatibility. This rear-mounted solution works seamlessly with lenses that lack front filter threads and can also be paired with external lens filters, allowing for flexible, multi-layered filtration setups.
