Get to know it

Choose your size

One polarizer, five MAG sizes.

Every size is the same glass in the same frame. Pick the MAG size of your JetMag Pro adaptor ring, not the thread on the lens.

MAG size is the filter's own size, not your lens thread. A JetMag Pro adaptor ring in the matching MAG size is what puts it on the lens, and it is sold separately: 39mm to 49mm threads go to 49MAG, 49mm to 67mm to 67MAG, 62mm to 82mm to 82MAG, 72mm to 95mm to 95MAG, and 82mm, 95mm or 105mm to MAXMAG. MAXMAG also has rings made for individual ultra-wide lenses with no front thread.

Already own JetMag Pro filters? Buy the polarizer at the MAG size you already use, and it goes on every lens that has a ring for it. If you would rather thread a polarizer straight onto the lens, the same film is in the screw-on True Color CPL.

How it works

Three moves, then turn it.

One ring per lens. After that the polarizer goes on and off in about a second, and it never has to be threaded.

Find your ring

Fit the ring

Thread a JetMag Pro adaptor ring onto the lens and leave it there. Every JetMag Pro filter in that MAG size then fits the lens.

Snap the filter on

The magnets catch the polarizer and seat it square on the ring. No threads to cross, even with cold or gloved hands.

Turn it to taste

Rotate the filter to set how much reflection comes off the scene. The patented locking design holds it in place, including when another filter is stacked on top.

Why this polarizer

True Color glass on a magnetic mount.

Two things had to be true: the film could not warm the scene, and the filter had to be quick enough that you actually use it.

No warm cast to correct

Most circular polarizers push the scene warm or yellow, and you spend the edit pulling it back out. NiSi uses an exclusive True Color polarizing film here, so skies stay blue and foliage stays green while the reflection goes.

02 / 08

On in about a second

The ring stays on the lens. The magnets pull the polarizer onto it and seat it square, so it goes on and comes off without threading, without cross-threading and without taking your eye off the light.

Turn it until the glare goes

Rotate the filter to pull reflections off water, wet rock, glass and foliage. Skies deepen, clouds gain separation, haze drops back, and what is under the surface of a pool comes through.

A lock, not just a magnet

A patented locking design holds the filter on the ring during the shoot. Point the camera down, hand the rig to somebody, walk with it on a strap: the polarizer stays where you set it.

Stack it with the rest

Put the polarizer under an ND, or a diffusion over both. Each JetMag Pro filter locks to the one beneath it, so a stack behaves like one piece of glass and travels as a single puck between caps.

Silver handles, found by touch

Every JetMag Pro filter has its own handle color and the polarizer's is silver. In a stack of four it is the one you can pick out without turning the camera around to read an engraving.

Slim enough to stay out of frame

The frame is ultra-slim, which is what keeps a polarizer off the corners of a wide lens. It matters more here than on most filters, because a polarizer usually has something else stacked on it.

Water and oil bead up

A low-reflective nano coating cuts internal reflections and repels water, oil and dust. Spray, drizzle and fingerprints stand up in beads on the surface and wipe off, instead of smearing across the front of the polarizer.

Reflections on glass

One photograph, split across the middle. Below the line is the bare lens: the sunlit face of the tower is a sheet of white glare with nothing in it. Above the line the polarizer takes that reflection down, so the glazing and the window frames come back and the sky holds an even blue.

Through the surface

On the left the shallows are a milky sheet of reflected cloud. On the right the polarizer takes that reflection off, and the pebble bed and the old fence posts running out into the water come through, with the blues left where they were.

Waterfall and rock pool

Without the filter the pool holds a pale sheen of sky. With it, the rust-colored stones on the bottom come through and the wet rock stops shining.

Mountain bay

Shallow water over rock, below a long escarpment. The filter takes the sky off the surface so the submerged boulders read, and deepens the sky at the same time.

Farmland and sky

No water in this one at all. This is the other half of what a polarizer does: a deeper sky, more separation in the cloud, richer color in the crop, and no shift in the tones that were already right.

Questions

Before you buy.

Which MAG size do I need?

MAG size is the filter's own size, not the thread on your lens. It comes in 49MAG, 67MAG, 82MAG, 95MAG and MAXMAG, and the one you want is the size your JetMag Pro adaptor ring is built for. Starting from scratch, pick the MAG size that covers your largest lens: 49MAG for 39mm to 49mm threads, 67MAG for 49mm to 67mm, 82MAG for 62mm to 82mm, 95MAG for 72mm to 95mm, and MAXMAG for 82mm, 95mm and 105mm as well as several ultra-wide lenses that have no front thread at all.

Do I need anything else to use it?

Yes. A JetMag Pro adaptor ring in the matching MAG size is what mounts the filter, and it is sold separately. The ring threads onto the lens and stays there, so you only buy one per lens and the filters move between them.

What does True Color mean on a polarizer?

Most circular polarizers add a warm or yellow cast that shifts skies and skin tones. NiSi uses an exclusive polarizing film here that is made to keep color neutral across a wide range of light, so what comes back needs less correction afterwards.

Is this the same glass as the screw-on True Color CPL?

It is built on the same NiSi True Color polarizing film. What differs is the mount: this one snaps onto a JetMag Pro adaptor ring and locks, rather than threading onto the lens, and it comes in the five JetMag Pro MAG sizes instead of thread sizes.

What does a CPL actually do?

It removes reflections and glare from non-metallic surfaces: water, glass, wet rock, foliage and painted surfaces. Rotate the filter to set how much. Along the way skies deepen, clouds gain contrast, haze drops back and you can see into shallow water.

Can I stack it with my other JetMag Pro filters?

Yes. It locks to the filter beneath it as well as to the adaptor ring, so a polarizer under an ND behaves like one piece of glass. The frame is ultra-slim, which is what keeps a stack off the corners of a wide lens.

Does it cost me light?

Yes. Every circular polarizer absorbs some light, so you lose a little shutter speed or gain a little ISO. Fit the filter and rotate it to where you want it before you meter, because the reading changes as it turns.

How should I clean it?

The nano coating repels water, oil and dust, so most of it wipes straight off. Blow the loose dust away first, then use a clean microfiber cloth. If you need fluid, use an alcohol-free lens cleaning fluid and never put anything containing alcohol on the coating. The NiSi Nano Optical Cleaning Kit has both.
