These filters should be called UV blocking filters, as there are filters for technical applications that transmit UV radiation and block all other wavelengths. Nevertheless, the short-term \"UV filter\" has become established among photographers. UV filters are ideal for photography at high altitudes (in the mountains), by the sea, and in areas with very clean air. Images gain brightness, and distracting blue casts are avoided. Because the glass is colorless, color rendering is not altered, apart from the elimination of unwanted blue casts, and no increase in exposure is required. This makes a UV filter very suitable as protection for the front element of the lens from dust, flying sand, seawater spray, and other contaminants, and it can be kept on the lens at all times. It is recommended for analog color and black and white photography, as well as digital photography.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003ch2 class=\"h2Lit\"\u003eKey Features of the B+W 77mm UV-Haze F-Pro Brass Ring - Premium German Optics\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eClear Protective Filter\u003c\/li\u003e\n\u003cli\u003eAbsorbs Ultraviolet Light\u003c\/li\u003e\n\u003cli\u003eReduces Bluish Cast of Daylight\u003c\/li\u003e\n\u003cli\u003e1x Filter Factor, No Exposure Change\u003c\/li\u003e\n\u003cli\u003eMRC Multi-Resistant Coating\u003c\/li\u003e\n\u003cli\u003eSchott Glass Construction\u003c\/li\u003e\n\u003cli\u003e77mm Front Filter Threads\u003c\/li\u003e\n\u003cli\u003eF-Pro Brass Filter Ring\u003c\/li\u003e\n\u003cli\u003ePlastic Case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\n\u003cbr\u003e\n\n\u003cdiv class=\"gText\"\u003e\n  \u003cdiv\u003e\n    \u003ch2 class=\"h2Lit\"\u003e\u003cspan class=\"h2Lit\"\u003eCoated to improve image quality\u003c\/span\u003e\u003c\/h2\u003e\n\n    \u003cp\u003eEach glass surface is vacuum-treated with a layer of anti-reflective coating.

Compared to the previous standard mount, the F-Pro mount, introduced in 2001, has become thinner. Now it can be used with wide-angle lenses, including most 24mm focal lengths on a full-frame camera body, without vignetting. Another advantage of the F-Pro mount is its redesigned retaining ring, which is no longer threaded from the front but holds the filter glass in place from the rear. When removing a filter or lens hood that has been screwed on too tightly, the retaining ring is not at risk of loosening.\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\u003cul class=\"mpn\"\u003e\n\u003cli\u003eMPN - BW70156\u003c\/li\u003e\n\u003cli\u003eGTIN - 4012240701568\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"B+W","offers":[{"title":"Default Title","offer_id":48983996203193,"sku":"148834","price":99.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/8897\/7337\/files\/35c0a473f654cde4ccc306f5ceddfebe.jpg?v=1787788430","url":"https:\/\/www.digidirect.com.au\/products\/b-w-77mm-uv-haze-f-pro-brass-ring-premium-german-optics","provider":"digiDirect","version":"1.0","type":"link"}
