FREEWELLStep Up Filter Adapter Ring 77mm-82mm (Works with Freewell M2 Magnetic Quick Swap as Well as Your Threaded Filter) Not Compatile with Freewell V2, K2, Eiger System

I bought 2 ND filters for my trip to Maui to do sunset timelapse photography at Haleakalā National Park. It worked like a charm. The filters had very little color shift. Also each of the ND filters came with a UV filter, which saved me some additional money. I mainly use the UV filters as a form of lens protector especially in dusty areas like Haleakalā Nation Park. Some of the trails into the dormant volcano were super dusty and this help make things easier to clean and less prone to damage.I got the largest size Freewell makes, the 82mm, just so i can use them on lens that i buy in the future that have a filter thread larger than 67mm. I did buy step-up rings from 67-82mm.Compared to Breakthrough Photography's magnetic lens filter system (which i know they are still in the process of redesigning) and PolarPro's screw on filter system, the Freewell magnetic filter system were super easy to use and change filters. Both those brand's filters easily run $150 to $200 each.The only caveat for the Freewell magnetic system is that you need to use screw on either the supplied UV filter lens, which the ND filter attaches to via the magnets. But luckily, if you don't like to use any filters in front of your lens such as UV filters, Freewell also includes a separate magnetic ring without any lens to work with the Magnetic ND filter. They also include a magnetic lens cover, that's made of metal, with all filter purchases.Best bang for the buck, for $250 i got 2 high quality ND filters (10-stop and 5-stop), as well as 2 magnetic UV filters and 2 magnetic filter rings and 2 step up rings. To get what I got from Freewell from the other top filter makers, it would of easily cost me over $600 - $700. Highly recommended!!!

This step up ring is so useful because it allows me to adapt my filters to fit multiple lenses rather than having to get a different filter for each different diameter lens I have. The build quality is outstanding and it even comes with a padded magnetic carrying case to keep it protected when you’re not using it. I use this on my Sony A7iii and 55mm diameter lens and it allows me to use my 67mm filter seamlessly without adding bulk.

Good

I like one ring to rule them all. Better than stacking. This brand makes good quality stuff for decent prices. Their magnet system is interesting but things can fall off if you bump it while walking. I screw things on.

The magnet is strong on this ring. I haven't had it get stuck on another filter but only time will tell. I gave it four stars because this adapter seems a bit pricey for what it is.

The adapter works perfectly and allows me to use my lens filter with a smaller camera lens size.

The stock that Amazon sent, is not compatible with the original Magnetic Quick Swap system, even though Amazon says it is. The packaging does not say "Quick Swap" on it.The ring *is* magnetic at various spots around the ring like all my other Freewell Magnetic Step Up rings that do work with my Freewell Magnetic Quick Swap CPL and ND filters, but does not "stick" to it when brought close.

I have a 67mm magnetic filter I've used on my 67mm thread lens with no problem. The magnetic connection is strong and great. But I bought a step up ring to adapt the filter to my 52mm thread lens and to my surprise the connection isn't nearly as strong. With the cap or an extra stacked filter on, the extra weight makes the filter easy to bump or shake off the adapter. I almost think I got a defective one or something. The magnetic strength is fine and passable, but it's not nearly as strong as the magnetic base ring that comes with the filter and doesn't give me confidence to not drop my expensive filter. I'd consider buying just a normal step up ring for the magnetic base ring instead.

Works well, leave it on, I also bought extra lens cap to match filter size and leave on.

Attention, contrairement à ce que le constructeur précise sur son site internet, cette bague step-up (52-67mm dans mon cas) n'est absolument pas compatible avec la version M2 de Freewell : l'aimantation est inversée et donc inutilisable quant à son usage initial.

It's beautiful 5 star for sure

Es justo lo que esperaba, con buenos acabados.

Ik heb deze aangeschaft en er uiteindelijk een UV filter opgeschroefd, dus had evengoed een goedkopere kunnen kopen zonder magneet.
