Include Magnetic Mounting Plate? (Only One Required Per Camera)

Fujifilm GFX cameras have a non-magnetic plastic inner mount. With this magnetic mounting plate you can easily convert your cameras to be compatible with our magnetic clip-in filters. Once installed, the plate makes your camera fully compatible. Only one plate is needed per body.

Items with pre-order status are in production and have not been made yet, and typically take a few months before they ship. Items "On Backorder" are temporarily out of stock, and may take several weeks to months until they are back in stock and ready to ship.

Kolari Magnetic Clip-in Filters For Fujifilm GFX G-Mount (Astro)

Enhance night sky clarity and reduce light pollution for astrophotography.

Our Kolari Magnetic Clip-in Filters for Fujifilm GFX (Astro) provide options to help enhance your Astrophotography images.

Crafted with the premium optical glass we’re known for, our Kolari Magnetic Clip-in Filters for Fujifilm GFX 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 Fujifilm GFX cameras. 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.

Our UV/IR Cut Filter (H-Alpha Pass) is specially designed for astrophotographers using full-spectrum converted cameras. It blocks unwanted ultraviolet and infrared light while allowing critical emission lines—specifically H-alpha (656nm) and Sulfur II (672nm)—to pass through, making it ideal for capturing deep-sky objects like nebulae with enhanced clarity and detail.

With a similar transmission profile to our standard UV/IR Cut Hot Mirror, this version offers an expanded spectral window tailored for emission line imaging. When paired with a full-spectrum modified camera, it delivers over 4× greater sensitivity to the H-alpha line and more than 6× greater sensitivity to Sulfur II compared to an unmodified stock camera. This dramatic boost in signal allows for shorter exposures, finer details, and better contrast in faint astronomical targets.

While designed with astrophotography in mind, this filter is also effective at minimizing IR contamination when used with stock unconverted cameras that experience residual IR leakage.

Our Kolari Magnetic Clip-in Filters for Fujifilm G-Mount are compatible with the following cameras: GFX50S, GFX50R, GFX100, GFX100IR, GFX100S, GFX50S II, GFX100 II, GFX100S II

We understand that Astrophotography can be challenging, but don’t worry, we have many resources and tutorials available for astrophotographers.

Here are a few of our most popular tips and tricks below:

Choosing a Full Spectrum or H-alpha Conversion for Astrophotography

Packing for Wilderness Backpacking for Astro and Infrared Photography

Narrowband Hydrogen Alpha Filters for Landscape Astrophotography

Choosing a Camera Brand for Astrophotography

Astrophotography thoroughly tests the optics of any camera system and lens. Ultrawide lenses are particularly challenging because of the high rear incidence angles involved where any additional glass has the possibility of inducing a field curvature which can cause loss of corner sharpness on a lens-by-lens basis; this effect is most noticeable at wide apertures. While this should always be a consideration with any ultra wide lens, we typically only see issues with astrophotography where the target subject is a series of geometrically perfect points of light at infinity, shot at wide apertures.
