Magnetic Filters
Simply screw an adapter ring into the filter thread once, and then each filter attaches magnetically and can be changed in a second. Here you’ll find magnetic ND filters, polarizing filters, UV filters, and Clear Night filters from Haida, as well as magnetic step-up rings and lens caps.
Why magnetic?
Anyone who’s ever swapped an ND filter for a stronger one at dusk with cold, numb fingers knows the problem. Screws take time, and time is exactly what you don’t have when the light is changing.
The benefit
The change takes one second instead of twenty—for every filter. During a sunset, when the brightness changes every few minutes, that’s the difference between getting the shot and missing it. As a bonus, the system solves two persistent annoyances: filters that get stuck and can’t be removed in cold weather are a thing of the past, and the lens thread isn’t stressed with every change.
How it’s set up
The basis is an adapter ring that matches your lens’s diameter and remains permanently screwed into the thread. All filters from the same series attach to this ring. Filters come in two versions: with their own adapter ring for beginners, or without a ring to add on if the ring is already attached to the lens. Be sure to pay attention to this when ordering, or you’ll end up with five rings and no use for them. Magnetic step-up rings also allow you to connect lenses of different diameters to the same filter set.
What You Should Know
The magnets are strong enough for normal use, but a hard impact can dislodge the filter. When shooting over water or from a bridge, it’s a good idea to take safety precautions. Stacking works, but becomes wobblier with each filter and, like screw-on filters, shifts forward. For more than two filters at a time, a slot-in filter system is the more stable solution. A practical bonus: Compatible magnetic lens caps stay on the same ring, so you save yourself the trouble of screwing the cap on and off as well.
