{"product_id":"tiffen-44sky-4x4-sky-1a-filter","title":"Tiffen 44SKY 4x4 Sky 1A Filter","description":"\u003ch2\u003eTiffen 44SKY 4x4 Sky 1A Filter | Square-format UV filtration\u003c\/h2\u003e\n\u003cp\u003eFor outdoor scenes, the Tiffen 44SKY gives you a square-format UV filter in the Sky 1A designation. It’s for photographers whose filter setup uses the 4x4 format and who want a dedicated filter for managing ultraviolet light. That makes it relevant for landscape work, travel photography and outdoor architecture, where a filter can stay in place as you compose a series of frames. The 4x4 format is the key practical detail: it tells you the filter’s format before you plan how it fits into your existing workflow. Sky 1A identifies this particular Tiffen filter, rather than a generic UV filter. There’s no need to treat it as a creative-effects filter; its appeal is a straightforward UV-filtering role in a specific square format. If that’s what your setup calls for, this is a clearly named option.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003e4x4 tells you this is a square-format filter, so I’d first match it to a workflow that already uses that format. In practice, it suits photographers building outdoor landscape or architectural images with a square filter setup; use it as the UV filter in that arrangement. The Sky 1A name is useful when you need this specific filter type again, rather than just searching for any UV filter. I’d keep expectations focused on that role: this isn’t described as an effects filter, and the product’s appeal is its 4x4 format and Sky 1A designation. If those are the details you need, it’s a straightforward one to identify.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Tiffen\u003c\/li\u003e\n\u003cli\u003eFilter format: 4x4\u003c\/li\u003e\n\u003cli\u003eFilter designation: Sky 1A\u003c\/li\u003e\n\u003cli\u003eCategory: UV filter\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tiffen","offers":[{"title":"Default Title","offer_id":57564036137300,"sku":"44SKY","price":220.46,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.htf-store.com\/zh\/products\/tiffen-44sky-4x4-sky-1a-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
