I needed the 77 mm filter and a 67/77 adapter. I have the proper size and so far delighted. It remains to be seen how time will effect the strenth of the magnet and the ability not to be knocked of. ONE MAJOR complaint though you cannot use the lens hood for whichever lens you are using with the magnetic ring and filter attached, this is a terrible design fault and should be attended to ASAP. Only if using a matte box can you shade the front element

With this ring you can complement the rest of your lenses and leave it ready to use K&F filters.

I've been looking for a single magnetic adapter ring for a long time, because Neewer apparently doesn't have one!
So if you have the Neewer filters and want to buy accessories, the K+F is a 100% suitable choice.

I've always disliked needing to screw and unscrew filters but with this one, the filter is attached via magnetism and can be put on or taken off with little difficulty. The only possible downside is there is a small amount of wiggle room with the filter installed. Does not affect image quality. I recommend k&f concept.

The filter system is great. You can also stack them. If you do stack them you may want to buy filters that are bigger than your lens and put on a step up ring. When you shoot wide you’ll avoid vignetting.
If you have multiple lenses that are different sizes I suggest buying this system for the biggest lens and get a step up ring for the smaller lenses.

J’étais sceptique au début du prix, puisque bien souvent les filtres plus dispendieux sont de meilleure qualité. Dans ce cas-ci je n’ai rien à dire, après plusieurs tests à 20mm et 420mm, la netteté est la même avec et sans filtre!! La seule affaire est une légère teinte bleue, mais elle est facile à ajuster en changement la balance des blancs en post-production.
Aussi, le concept magnétique est super!! Beaucoup plus facile à utiliser et très bien sécurisé avec la force de l’aimant (j’ai tenté de secouer un objectif avec le filtre et ça a tenu).
Finalement pour ma part la bague se visse parfaitement à mes objectifs Nikon et ne reste pas pris ou en « cross tread » comme plusieurs personnes qui semblent avoir des problèmes avec les filtres.

Perfect budget-conscious variable ND for our Nikon lens. Construction seems durable, and vignetting is not noticeable unless super stopped down. I can't compare it to the higher priced brand name versions, but I have no complaints.

Have had the opportunity to use this filter. Quality of materials is very good. No noticeable colour cast which is important. Magnets hold strong. Very pleased and great value for the cost.

Very nice filter for the money. My photos colors are very nice using this filter and it allows me to slow my shutter speed for great waterfall pictures.
