Haida NanoPro Magnetic ND Filter ND 3.0 1000x 10-Stop 67mm without Adapter Ring

You want to expose for half a minute in the middle of the day so the lake turns to glass and the clouds streak across the sky? That takes 10 stops, and that is what the Haida NanoPro Magnetic ND 3.0 in 67mm delivers. It holds magnetically on the adapter ring and snaps on in a second. Please note: this filter ships without an adapter ring. If you do not own one yet, you need to order the ring separately.

• ND 3.0 (1000x): cuts light by 10 stops
• Magnetic mount: snap on instead of screwing in
• Glass just 0.8mm thin, stackable with other Haida magnetic filters
• Scratch-resistant, water- and oil-repellent NanoPro coating
• Supplied without magnetic adapter ring

Long exposures in broad daylight

Ten stops turn fractions of a second into whole seconds

The filter lengthens your exposure time by a factor of 1000. 1/60 s becomes roughly 15 seconds, 1/15 s a good minute. Moving water turns into a smooth surface, clouds draw streaks across the sky and passers-by vanish from a busy square.

Focus first, then add the filter

Through a 10-stop filter you see next to nothing in the viewfinder, and autofocus often hunts. With a screw-in filter that means: filter off, focus, screw it back on and hope nothing shifted. Here you frame and focus while the image is still bright and simply snap the filter on afterwards. The focus ring stays where it is.

Thin glass, tough coating

The glass is only 0.8mm thick, so the filter sits very flat. The NanoPro coating is scratch resistant and repels water and oil. Spray on the shore or a fingerprint wipes off quickly with a microfibre cloth.

Works on smaller lenses too

With a Haida magnetic step-up ring, the 67mm filter also fits lenses with a smaller filter thread, such as 62mm. The step-up ring doubles as the adapter ring, so that lens needs no second ring.

What this looks like in practice

At the lake around midday

The camera is on the tripod and the adapter ring is on the lens. At f/11 and ISO 100 the camera meters 1/60 s and the water is choppy. You focus on the jetty, switch to manual focus and snap on the ND 3.0. Now you expose for around 15 seconds: the waves are gone and the jetty stands sharp above a calm surface. If a cloud moves in front of the sun, you take the filter off, meter again and put it back on.

What you should know before ordering

The adapter ring is not included

The filter has no screw thread and cannot be mounted directly on a lens. You need either the Haida magnetic adapter ring in 67mm or a magnetic step-up ring to 67mm. If you already own a Haida magnetic filter with ring, you have everything you need.

A tripod is a must

With 10 stops you are always shooting in whole seconds, which cannot be handheld. For exposures beyond 30 seconds you also need bulb mode and a remote release with timer. On DSLRs it is worth covering the viewfinder so no light leaks in from behind.

Too strong for soft water with texture

If you only want to blur a stream slightly or you are shooting at dusk, exposure times with 10 stops quickly become impractically long. The magnetic 6-stop ND filter is the better choice there. The two can be stacked, but with every extra filter the risk of darkened corners on wide-angle lenses increases.

The magnet holds, but not against hard knocks

In normal use the filter sits securely. A solid bump against the lens can dislodge it, though. Keep that in mind over water, on a bridge or in a crowd.
