Easy modification to new lens to allow use of magnetic filters

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.

Needs stronger magnet

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 bought the wrong size

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

Great for use on more targets

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

Also fits with Neewer magnet filter

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.

Magnetic filters are super useful

Great image quality, no noticeable colour cast.
Magnetic ND filters are a must due to constant manual focusing adjustment in between compositions. So much faster than screwing on/off filters. The lens cover is also incredible!

Very cool design

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.
