Learn how to install and use the NiSi JetMag Pro True Color CPL MAXMAG magnetic polarizer. Follow these steps to avoid color cast and get clean polarization.

Quick answer

Attach the NiSi JetMag Pro True Color CPL MAXMAG to a compatible lens or step-up ring, then rotate the filter to control reflections. The magnetic mount lets you snap it on and off quickly, but you still need to align the polarizer correctly for even polarization.

Why the magnetic mount changes your workflow

The MAXMAG magnetic system is designed for speed: you can attach or remove the CPL without screwing it on. That convenience matters when you are switching between polarized and non-polarized shots, but it also means you need to check that the filter is seated flat before each shot. A partially attached filter can cause uneven polarization or vignetting.

Because the filter rotates freely once mounted, you can adjust the polarization effect by turning the outer ring. This is especially useful for landscape photography, where you may want to darken the sky or cut reflections from water. However, the magnetic hold is not a lock—avoid lifting the camera by the filter or storing it attached in a bag where it could be knocked off.

When to use a True Color CPL instead of a standard polarizer

The NiSi JetMag Pro True Color CPL is built to minimize the warm or yellow shift that some polarizers introduce. If you shoot scenes with critical color accuracy—such as foliage, blue skies, or product photography—this filter helps preserve natural tones. That said, no polarizer is completely neutral; you may still see slight color changes depending on the angle of light and your camera's white balance settings.

For situations where you need maximum reflection control and can accept a slight color shift, a standard CPL may suffice. But if you want consistent color across a series of images or plan to stack filters, the True Color design reduces the need for post-processing corrections.

Step-by-step setup and usage

Attach the magnetic adaptor ring: Screw the MAXMAG adaptor ring onto your lens filter thread (or use a step-up ring if needed). Hand-tighten only; over-tightening can make removal difficult. Checkpoint: ensure the ring sits flush against the lens front. A cross-threaded adaptor will prevent the filter from sitting flat.
Snap on the CPL filter: Bring the NiSi JetMag Pro True Color CPL close to the adaptor and let the magnets pull it into place. Rotate the filter slightly until it seats evenly. Checkpoint: the filter should not wobble or sit at an angle. If the filter feels loose, remove it and check for debris on the magnet surfaces.
Rotate to adjust polarization: Look through the viewfinder or at the live view screen and turn the outer ring of the filter until you see the desired effect—typically maximum reflection reduction or sky darkening. Checkpoint: avoid over-rotating past the point of maximum effect, which can cause uneven polarization in wide-angle shots. For wide lenses, rotate slowly and check the corners for uneven sky density.
Verify color neutrality: Take a test shot and review the colors on your camera's LCD. The True Color design should keep whites neutral and blues natural. Checkpoint: if you notice a strong warm cast, ensure the filter is the only polarizer attached and that your white balance is set appropriately. Stacking a second polarizer or using a warm-tinted filter will negate the True Color benefit.
Remove before storing: Slide the filter off the adaptor when not in use. Store it in a case to protect the glass and magnets. Checkpoint: leaving the filter attached during transport can stress the magnetic mount or cause accidental detachment. Keep the adaptor ring on the lens if you plan to reattach frequently, but cap the lens to protect the ring.

Product facts

NiSi JetMag Pro True Color CPL MAXMAG Magnetic Filter: True Color Polarization with No Color Cast – Eliminates unwanted reflections from water, glass, and other non-metallic surfaces while preserving accurate, natural color reproduction. This means you can cut glare without introducing a warm tint, so skies stay blue and foliage stays vibrant straight out of camera.
