The Cokin H521 set includes the Cokin P BP-400 holder, P197 filter - sunset 1, adapter and a box for 4 Cokin P filters. Cokin filters are mounted using a holder (holder), which is attached to replaceable mounting adapters, with diameters that can be adapted to your lens. The P system is recommended for compact system cameras with interchangeable optics (mirrorless) and amateur SLRs with APS-C matrixes used with kit or long focal length lenses. It can also be used with small video cameras. The sets have a written dedication to the specific camera brand on the packaging, but they will work the same way with any other camera and lens with a matching thread diameter.
