This set includes a UV filter, CPL filter, FLD filter, and ND2, ND4, and ND8 filters. Features: Compatible with 55mm lenses. The UV filter absorbs ultraviolet rays, helps provide clearer images, and protects your lens from scratches, scuffs, and smudges. The circular polarizing filter (CPL) enhances color and contrast by reducing reflections from non-metallic surfaces such as water or glass. The fluorescent light correction filter (FLD) provides color correction when shooting under fluorescent lighting. The ND filters (ND2, ND4, ND8) allow the use of slower shutter speeds in bright light conditions, enabling the use of larger apertures for achieving a shallow depth of field. Includes two storage bags, a lens cap to protect the filters, and a lens cap strap to help prevent loss.
