K&F CONCEPT 67mm Magnetic CPL Filter Polarizing, Magnetic Adapter Ring with Alloy Lens Cap, Circular Polarising Multi-coated Optical Glass for DSLR Cameras (Nano-X Series)

These filters are excellent, prosumer grade. With top quality glass and very little colour cast. The magnetic mounting system is super quick and easy to use and strong enough to be sure the filter doesn't fall off accidentally. By all accounts they are almost indestinguishable from top quality professional systems but at an affordable price. I wouldn't hesitate in recommending them and have gone on to purchase more filters from the range.

Easy to change or stack these filters with good optical qualities.

It is a good cost-effective product.The Alloy Lens Cap needs to be improved， as it is difficult to take it on or off with lens hood .The pictures I uploaded was modified by me. It is much easier to use.

I love the portability of this filter kit and the magnetic attachment is great. They don't break the bank price wise but the quality seems very decent. I haven't compared results with the CPL against the one for my square filter set but images taken with the CPL are crisp and sharp and don't seem to have any colour cast to them.The magnetic lens caps are superb too. I've actually got adapter rings and the caps for all my lenses now as I find them so much nicer to use than the plastic ones that come with lenses.In summary they're good filters for a good price and the magnetic system is brilliant. Maybe for ultimate quality you'd still be better off with a proper square filter set but being able to carry a CPL in your pocket is way more convenient and the quality is great!

Very well made. The magnet is strong enough to keep the filter and cap in place under normal use, but could be knocked off when removing camera from bag. Overall great concept I have ordered more filters in the range and step down adapters to fit them on other lenses.

I am now using my polarizing filter far more sim ple because it's so easy to put on and take off.

I love the convenience of Magnetic filters , although I have many 100/150cm Nisi/lee filters with holders, so worried more about the quality of the filter rather than ease of use, it has to have both. I havent used yet to compare. I bought also the magnetic ND filter so stacking is easy. However 1 serious ommission on the design front, you Cannot use the lens hood of whichever lens you are using. This seems a terrible mistake by the designers. I would rather use a normal filter with lens hood than these without. If a lens hood could be used it would be 5 stars , without its a BIG mistake design wise

I had reservations on the strength of the magnet but it has been very good. Only dropped them once but that too was purely my fault. Otherwise, pretty good quality as expected and great value for money.
