Choose the 6-stop OKKO Magnetic Pro ND for flexible daylight motion blur, or the 10-stop for long-exposure water and clouds. Match the thread to your lens and buy the adapter ring separately.
Quick answer
Pick the 6-stop OKKO Magnetic Pro ND when you want controllable motion blur in changing daylight; pick the 10-stop when you need very long exposures of water, clouds or empty streets. Then match the filter thread to your lens and budget for an Okko magnetic adapter ring or magnetic UV filter, which is sold separately.
What the stop difference actually changes
The 6-stop and 10-stop versions are both neutral density filters, but they cut light by very different amounts. A 6-stop filter gives you more shutter-speed headroom than a bare lens while still letting you see and compose easily; a 10-stop filter pushes exposures into the tens of seconds in normal daylight, which is why it is the classic choice for long-exposure water and moving clouds.
That extra darkness is not automatically better. The more light you remove, the harder it becomes to autofocus and frame without recomposing, and the more likely you are to need a sturdy tripod and a remote release.
Why the magnetic mount matters for filter changes
Okko's magnetic system lets you swap a filter without unscrewing it from the lens, which is useful when light is changing and you want to move between no filter, a 6-stop and a 10-stop quickly. The catch is that the magnetic adapter ring or magnetic UV filter is not included with these ND filters, so the first purchase is really a system purchase.
Both filters use slim aluminium frames and 16 layers of anti-reflection and anti-fingerprint coating on German-engineered B270 Schott glass, and both are all-weather sealed. Those shared traits mean the stop value and thread size, not build quality, should drive your decision.
Thread size: match the lens, not the filter you wish you had
The 6-stop is listed here in 77mm, while the 10-stop is offered in 72mm and 82mm. That is a practical limitation: you cannot choose any stop value in any thread size from this selection, so check the filter thread printed on your lens before deciding.
If you shoot several lenses with different threads, buy for the largest thread you use and plan on step-up rings, or accept that one filter will not fit every lens. The slim frames help avoid vignetting on wide lenses, but slimness does not solve a mismatched thread.
Decision rules for buying an OKKO Magnetic Pro ND
- Choose 6-stop if your exposures are handheld or mixed: Buy the 6-stop when you want to blur moving people or water slightly while still shooting in changing light, or when you do not want to carry a tripod for every shot. If you regularly shoot without a tripod, start with 6 stops.
- Choose 10-stop for deliberate long exposures: Buy the 10-stop when your goal is smooth water, streaked clouds or near-empty streets in daylight and you are prepared to use a tripod and manual focus. The 10-stop is a specialist tool, not a general-purpose walkaround filter.
- Check the thread before you check the price: Measure or read the filter thread on your lens. This selection offers 77mm in 6-stop, and 72mm or 82mm in 10-stop; if your lens is a different size, plan for a step-up ring or choose another option. A filter that does not fit your lens is not a bargain at any price.
- Budget for the magnetic adapter: Add an Okko magnetic adapter ring or magnetic UV filter to your basket, because the ND filter alone will not attach to your lens. Treat the adapter as part of the filter's real cost.
Product facts
- OKKO Magnetic Pro ND Neutral Density Filter 6 Stop 77mm: 6-stop neutral density filter in 77mm, with German-engineered B270 Schott optical glass and 16 coating layers. A useful middle density for slowing shutter speeds in daylight without making composition and autofocus difficult.
OKKO Magnetic Pro ND Neutral Density Filter 6 Stop 77mm - OKKO Magnetic Pro ND Neutral Density Filter 10 Stop 72mm: 10-stop neutral density filter in 72mm, requiring an Okko magnetic adapter ring or magnetic UV filter sold separately. Best suited to long-exposure work on 72mm lenses, but the adapter cost and availability must be part of the decision.
OKKO Magnetic Pro ND Neutral Density Filter 10 Stop 72mm - OKKO Magnetic Pro ND Neutral Density Filter 10 Stop 82mm: 10-stop neutral density filter in 82mm, with the same B270 glass and 16-layer coating specification. Gives owners of 82mm-front lenses the 10-stop option without stepping down, which matters for wide lenses where vignetting is a concern.
Who should buy which
Best for
- Landscape and city photographers who want a quick-change magnetic ND system
- Travel shooters who want one 6-stop filter for flexible daylight motion blur
- Long-exposure specialists with 72mm or 82mm lenses who need a 10-stop
Not for
- Photographers who want a single filter to fit every lens thread without adapters
- Buyers who have not confirmed they own or will buy an Okko magnetic adapter ring or magnetic UV filter
- Anyone expecting a circular polariser or graduated filter in the same purchase
