I use the K&F magnetic filter system and when I get a new lens, I need to set it up to take advantage of using this magnetic filter system. To do this, if the filter threads are the common 77mm, all that is required is adding one of these empty magnetic filter rings to the lens’ filter threads. The lens is then ready to accept all the different magnetic filter elements in my kit. The nice thing about using a magnetic filter system is there is no worry about threading and unthreading a filter onto a lens in the field and getting it cross-threaded or dropping the filter while trying to do it. Simply pop it on and pull it off. That simply.

The variable ND I attached to this, works awesome. However I the filter has already popped off a few times. Luckily I was over grass so I just had to clean the glass. I bought a few for my lenses and different sizes too. Will have to be VERY careful and make sure not too bump into the side of the filter!

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.

Also interesting experiments on the magnetic filter K&F, so that the system is comfortable and can be relação custo-beneficio. Este adaptador de filtro magnetico com filtros K&F é exatamente o que eu quero.
