Variable ND filters that allow you to enjoy full-scale long exposures with your smartphone
K&F CONCEPT's variable ND filter (67mm) was an item that expanded the range of expression to such an extent that I couldn't think of shooting with a smartphone. ND2 to ND32 can be adjusted with a single image, making it possible to express expressions that were difficult with conventional smartphone cameras, such as waterfalls and river flows during the daytime, and light trail photography of night scenes. There was little color coverage, and thanks to the nano-coating, there was almost no deterioration in image quality. The clip, which can be attached with one touch, is also very convenient, and can be fixed without putting stress on the smartphone. It's also lightweight, making it perfect for shooting on the go. The silicone pad prevented slipping, and I was able to use it stably in both vertical and horizontal shooting. Since it is compatible with the 67mm standard, the fact that you can make use of your camera filter assets on your smartphone is also attractive. Recommended for those who want to rank up their smartphone photography.
