I regularly go out in nature with my dog and carry around my Nikon D750 with various lenses, the most important of which all have a 77 mm thread. Especially in the forest and in the Harz Mountains, I always use a polar filter to reduce reflections from leaves and water. The only problem is that pole filters always take light and you have to extend the exposure time accordingly, which is disadvantageous if I want to spontaneously photograph my dog. Until now, I've been skeptical of magnetic filters because I wasn't sure whether the grip would be sufficient when hiking through nature with the camera and filter mounted. Accordingly, I welcomed the opportunity to test this filter from K&F as part of the Vine program.

I have already had very good experiences with K&F products. Your program covers a very wide range, but there are some of your products that are of very high quality but are definitely aimed at ambitious amateur photographers precisely because of their lower prices. This filter is also one of the better products, which you immediately notice when you unpack it. The filter is very neatly finished, the magnetic thread and filter are a perfect fit. The filter comes in a matching box, and there is also a lens cloth that is well protected in aluminum packaging. Overall, it all makes a very good impression.

The thread is easy to screw onto the lenses, the magnet pulls the filter well into position and holds it very firmly so that the filter can be rotated easily without slipping in position. Since this is a slim design, it barely affects the image even with the wide-angle lens at 16 mm. My fear that a magnetic filter might fall off while hiking has made this filter clear. It really sits securely and firmly on the lens. However, it can be removed very quickly if necessary, which is much more convenient than lengthy unscrewing. For me, this is a significant improvement in the handling of filters in outdoor photography, where you often have to adjust your equipment spontaneously. I think I will now focus more on using magnetic filters, the test has convinced me of the functionality.

The filter performance is clearly in the better range of the pole filters that I use. There are really big differences in the reduction of reflections and color accuracy, and you have to invest quite a bit if you want reliable filter performance. I am very satisfied with the performance of this filter, you can clearly see how reflections are diminishing when turning.

Overall, this is once again a highly recommended product from K&F.
