49mm Empty Magnetic Base Ring (Works ONLY with K&F Concept Magnetic Filters / Quick Swap System)
SKU: KF05.283
This works so well and has earned a spot in my camera bag. It worked so well, I ordered one more lens size.

I've bought a few things from K&F Concepts over the past few months. ND filters, a Camera Backpack, and a tripod. The magnetic ND filters are wonderful (see an example of a long exposure with K&F Concept 1000ND filter attached), these make me very happy.
The bag I bought was very good for the cost (around £70, but have since changed this again as my kit size and level have changed a lot, but that's no poor reflection on K&F Concepts, I simply needed a larger volume.
The tripod was an unfortunate experience, I had some issues with it and returned it for a full refund., which K&F Concepts honoured without any fuss. Great.... I then received an email from K&F Concept's Customer Service Manager (Rina Kuromiya) reaching out with concern about my review of the tripod. I was offered a compensatory gift which I had a choice of either picking anything from their product range to the value of the tripod I purchased, or I could take a gift voucher of a set value. I chose to take the products from their range and have even more magnetic filters from them and I couldn't be happier. Delivered the following day!
K&F Concepts' aftersales service and customer care are amazing. A lot of other companies could learn a lot from these. Yes, I would highly recommend them and will be purchasing more equipment from them in the future. - if Rina Kuromiya is reading this, I thank you sincerely, and would be more than happy to be a product tester for K&F Concepts ;)

I took this out for a little testing. I was able to get some good 60 second exposures on a bright sunny day. The sun was around 2p and no clouds in the sky.
On a couple of the photos at the river there is a showing of some slight vignetting in the upper left corner. It is easy to crop out, but it is there nonetheless. It should be noted that the vignette occurred at 24mm and I did have a CPL filter covering the ND1000.
There "may" be some color casting as well. It could have been the angle of my scene, however, and the CPL might have interfered. I won't knock it for color cast.
The magnetic design makes this so easy to use. When stacking, it can take some extra care to remove some of the filters without removing all of them.
Overall, I'm happy with these filters. I searched way too long among what is available at this time, and ended up with these. I'm glad I made the choice.

Pros:
- affordable price
- high-quality workmanship
- system can be used with adapter ring or UV filter as basic elements
- very good coating of the filters without negative color shifts or visible loss of sharpness
- no vignetting from 15mm onwards
Cons:
- bag does not correspond to the quality of the filters
- CPL filter at 14mm, slight vignetting
- unfortunately no other ND filters are currently available for this system.
Conclusion:
a more than successful set that is worth every euro, not just for beginners in the subject. Ambitious users will also find a good alternative to the filters of established brands here.
We can only hope that K&F brings more of these magnetic filters onto the market because I would like to have another ND8 and ND64.
Therefore, I can, in good conscience, give a very clear purchase recommendation

I've been wanting to try these K&F Concept Magnetic Filters since they were announced.
I'm glad I bought these. They are great,
super easy to use and swap out in the field. Simply attach
the magnetic ring to your lens and then it's just a case of attaching and changing the filters with ease,
No hassle screwing the filters in and out, this is a game changer in my opinion, I own a bit of K & F gear and these are good quality as always.
I have the K&F square filter kits but that's a lot easier, the case that comes with it is really nice too,
they're not cheap but they're not cheap but
they're a lot easier get what you pay for, I'm extremely happy overall
