K&F Concept Lens Filters
Although it's usual for photographers to use filters to protect their lenses from scratches, thumbprints, and dust, the real benefit lies in the way filters improve images and, in some instances, achieve effects that even the best photo editing suites cannot replicate. There are many different types of lens filters, each for a specific purpose. Filters attach in one of two ways. The most common are circular filters that directly screw onto the lens. The second method is to use a filter holder that accepts universal type rectangular filters. This is useful if you use multiple filters to obtain different effects.
