{"product_id":"urth-39mm-magnetic-infra-red-r72-filter-plus","title":"Urth 39mm Magnetic Infra-Red (R72) Filter Plus+","description":"\u003ch2\u003eUrth 39mm Magnetic Infra-Red (R72) Filter Plus+ | A magnetic route into infrared photography\u003c\/h2\u003e\n\u003cp\u003eThe R72 designation is the defining choice: this is a dedicated infrared filter for photographers who want to explore infrared imagery, rather than a general-purpose filter. Its 39mm size makes it a specific fit choice, so it’s worth matching that diameter to the filter size you need before planning a setup. The magnetic design gives the filter a different way of attaching, which may suit photographers who prefer magnetic filter handling. It’s best for deliberate experiments with infrared photography: trying a different visual approach to landscapes, foliage or architecture, and seeing how familiar subjects translate through an infrared filter. The Plus+ name identifies the version, but the information available doesn’t support claims about its materials or optical performance. This is a focused creative tool, not a UV filter or an everyday protective filter. Choose it for the infrared effect you want to explore.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003ePhotographers who like reworking landscapes, leafy scenes and architecture into infrared images are the people I’d point towards this Urth. The R72 marking tells you its purpose is infrared photography, so approach it as a specialised effect filter, not an all-day lens protector. Its 39mm size is the detail to get right for your setup; the diameter matters when choosing a filter. The magnetic attachment is useful if magnetic handling is how you prefer to fit filters. I’d start with a simple, well-composed subject and compare the result with your usual approach. One honest point: this is a narrow-purpose filter, so it makes most sense when you’re keen to make infrared work a part of your photography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFilter diameter: 39mm\u003c\/li\u003e\n\u003cli\u003eFilter type: Infra-red (R72)\u003c\/li\u003e\n\u003cli\u003eAttachment: Magnetic\u003c\/li\u003e\n\u003cli\u003eSeries: Plus+\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Urth","offers":[{"title":"Default Title","offer_id":57492255998292,"sku":"D309451","price":40.51,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/D309451_01.jpg?v=1791544730","url":"https:\/\/www.htf-store.com\/zh\/products\/urth-39mm-magnetic-infra-red-r72-filter-plus","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
