Hot Mirror Clip-in Filter For Sony FE – Magnetic

Kolari Magnetic Clip-in Filters For Sony FE-Mount (UV/IR Cut) are designed to block ultraviolet and infrared light while allowing only visible wavelengths (400–700nm) to pass through. This makes it essential for photographers using full-spectrum cameras who want to shoot in normal visible light. By cutting out these unwanted wavelengths, the Hot Mirror Filter restores natural color accuracy, improves sharpness, and delivers true-to-life results.

Engineered with the professional-grade optics that Kolari is known for, these filters are securely housed in a CNC-machined aluminum magnetic frame designed to maximize lens compatibility. This universal solution fits perfectly with lenses lacking filter threads and can be paired with external lens filters for added filtration effects.

Compatible with Sony FE cameras. (See compatible cameras below)

Also known as a lowpass filter or UV/IR cut filter, our UV/IR Cut Color Correcting Hot Mirror Filter blocks infrared light and some UV, and allows a full spectrum converted camera to take normal pictures. Our hot-mirror filters include an anti-reflective corrosion resistant coating, which reduces artifacts and increases durability of the filter in humid regions.

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.

A common question that people have while converting their camera to full-spectrum is whether or not they can still shoot in “regular light.” The short answer is yes, you absolutely can. The long answer is that with an external filter that’s designed to cut UV and IR light, the image will be taken within the visible light spectrum but some filters can just be a bit off in auto white balance.

This is exactly why we’re proud to introduce the next generation of filters of its kind, the Kolari Hot Mirror Pro 2. With more than 50 layers of optical coating put on over a 10 hour period, each Hot Mirror Pro 2 is made with quality and precision in mind.

When we introduced our original hot mirror filter, we optimized the spectral response to match the cameras that were on the market at the time as closely as possible. Now almost 10 years later, cameras have changed and our filter manufacturing capabilities have improved. We may have had the best hot mirror on the market already, but we’ve taken things a step further and outdone ourselves with the Hot Mirror Pro 2. We can now achieve even higher color accuracy and virtually identical performance to stock cameras with an auto white balance.

Compatible with: Sony A7, Sony A7II, Sony A7III, Sony A7R, Sony A7R II, Sony A7R III, Sony A7R IV, Sony A7R V, Sony A7S, Sony A7S II, Sony A7S III, Sony A9, Sony A9 II, A7 IV, Sony FX3, Sony A1*, Sony A7C*, Sony A7C II* Sony A7 V

NOT compatible with Sony FX6

*The Sony A1 & A7C require a magnetic mounting plate to work with our magnetic clip-in filters. If you own an A1 or A7C, please select “YES” in the “Magnetic Mounting Plate” drop-down menu.

Our Hot Mirror filters require a full-spectrum converted camera and will not produce the intended effects on stock, unmodified cameras.
