The Fotodiox Glass Filter Kit contains three must-have filters for every photographer. The kits come with a UV filter, a Circular Polarizer, and a Soft Diffuser. The UV Filter helps with clarity in sunny or hazy conditions and is super multi-coated to minimize reflection and reduce flares and ghosting. The Circular Polarizer removes unwanted reflections from non-metallic surfaces and the Soft Diffuser softens landscapes and skin texture in portraits.
