Product Features in Detail

Snap On in Seconds
The JetMag Pro 49MAG magnetic system is built for speed and reliability, using strong magnets to hold each filter securely in place. Filters snap on or off in seconds, so you can adapt to changing light without breaking your flow—and the stackable design lets you combine multiple filters effortlessly for maximum creative control on the go.

Locked On Tight
JetMag Pro 49MAG features a secure locking mechanism that keeps your filters firmly in place, even during fast movement or rough conditions. Simply twist the filter until it aligns with the white line on the adaptor to engage the lock—giving you complete confidence that your filters won't shift or detach while you shoot.

Color-Coded Control
Every 49MAG filter has its own color-coded handle, so you can identify the look you want at a glance and grab it fast. The tactile handles make it easy to attach, stack and remove filters by feel—even in low light—keeping you focused on the shot instead of your kit.

One Filter, Many Lenses
Fit a 49MAG adaptor ring to each of your lenses—available in 39mm, 40.5mm, 43mm, 46mm and 49mm—and a single filter works across them all. Move one filter from lens to lens in seconds, with no step-up rings or extra gear, saving time and space in your kit.

Every Creative Look
From True Color CPL and Full-Spectrum ND to Black Mist, Pure Mist, Film Glow, HDF, Cross Screen and the Yellow, Orange and Red monochrome filters, the 49MAG system covers every creative look on one magnetic platform—so you can build your kit and switch between effects in seconds.

Built for the Field
Premium optical glass and NiSi's low-reflective nano-coating cut glare while repelling water, oil, dust and fingerprints, so your filters stay clean and wipe down easily. Slim, aerospace-grade aluminium frames are built to handle real-world shooting, wherever the day takes you.

Fits in Your Pocket
The whole 49MAG system is made to travel light. Slim filters, magnetic caps and the compact Caddy Pouch keep everything protected and organised in a package small enough to slip into a pocket—so you can carry every look without the bulk of traditional filter cases.
