It suits anyone who wants a layer in front of the lens during regular shooting, especially when working around dust or everyday handling. The Ceramic Protector name identifies its material, while WR is part of the product designation. Its best use is straightforward: fit it to a lens with a 95mm thread and keep it in place when you want front-of-lens protection. This isn’t a filter for changing exposure or adding a colour effect; its role is protection. If your lens takes a different filter size, this 95mm version won’t be the right fit.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003ePhotographers making landscape frames with a large-front-element lens, or working around dust and everyday handling, are the people I’d point toward this Sigma. The 95mm size is the practical detail to get right: it belongs on a lens with a matching 95mm filter thread, and won’t fit just because the lens looks large. The ceramic construction is the product’s defining material, while its role is plain protection, not an exposure or colour effect. For dusty viewpoints, leave it fitted while composing, then clean the filter surface rather than wiping the front element directly. It’s a focused accessory, not a creative filter.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Sigma\u003c\/li\u003e\n\u003cli\u003eDiameter: 95mm\u003c\/li\u003e\n\u003cli\u003eFilter type: Protection\u003c\/li\u003e\n\u003cli\u003eConstruction: Ceramic\u003c\/li\u003e\n\u003cli\u003eDesignation: WR\u003c\/li\u003e\n\u003cli\u003eModel: PTC-21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sigma","offers":[{"title":"Default Title","offer_id":57512907473236,"sku":"AFJ9E1","price":253.26,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.htf-store.com\/es\/products\/sigma-filter-95mm-wr-ceramic-protector-ptc-21","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
