After a long search and cheaply processed Chinese parts, I have finally found a high-quality set of filters for my Dji Mini 2. The frame is made of aluminum and fits perfectly. See photos. Nothing wobbles, no fumbling and you don't torture yourself during assembly. Ok, you should show some fine motor skills when you put them on the gimbal but otherwise, as I said, very easy because it fits perfectly. Tip: Cotton gloves avoid greasy fingerprints. Handy if you often change filters on the go. K&F is a manufacturer of various aperture filters in the professional field of photography. Accordingly, the quality has failed. Just great. Image material of my videos is therefore first class. There are filters for all imaginable lighting conditions in the storage box. By the way, this is made of transparent plastic and lined with foam. The filters are protected in a practical and space-saving way. In terms of price, the large set is really worth every cent. At the latest when you look at his videos, you are not happy that you have saved money in the wrong place. My conclusion: If you are looking for quality, this is the place for you.
