The K&F Concept Magnetic Filter Kit is available from 49 to 82mm sizes at $110 to $149. I personally can’t wait to put these to good use with my dp Quattros, and with lockdown easing in Scotland, I can start to plan some trips. It’s easy to recommend the K&F Concept Magnetic Filter kit to anyone looking for such a solution. Starting at $110 for three filters, a magnetic adaptor with a nice pouch to carry them all in. So as you can imagine, I’m a happy man and found a great little kit to use on both cameras. Using the magnetic adaptor ring, CPL and 10stop gave no vignetting on the Sigma dp0. Luckily though it wasn’t an Issue on the Sigma dp3q, I then tested it on my 14mm dp0, which I was sure would be affected. A way around this would be to buy a larger version and use a step-up ring. Here’s a photo of the combo used for the above shot, and as you can see, stacking the filters makes it protrude quite a bit, which could lead to vignetting on some cameras. The UV filter seems not to affect image quality here, while the CPL and ND add a little bit of color cast. This image was taken with the CPL and 10Stop ND on my Sigma dp3Q.Īnd here are some crops without a filter, with the UV, then CPL, and finally the all three.Īs you can see, even when attaching all three filters, the sharpness is still fine.

Allowing you to switch filters between lenses quickly. This lets you keep the Magnetic adaptor ring on one lens and the UV on a second.
One of the nice things about this kit is that you can attach the UV filter to the lens in two ways: 1.
I was concerned about the filters falling, but even when I was jumping around with the camera, the filters stayed firmly in place. Removing the filter is just as simple as popping it off. Snap! The filter is now securely in place. You screw the Magnetic Adaptor ring onto your lens and then place the magnetic filters on top. The pouch also has a velcro belt loop on the back to attach to other bags, belts, or even your tripod, as well as a D ring for hanging or attaching onto things.Īs I was looking for a nice compact kit to complement my Sigma dp3q and dp0, I opted for the 58mm versions.
