The Tokina 112mm Pro IRND 2.4 is a neutral-density filter for reducing the light reaching the camera, so you can use a longer exposure without relying on a darker scene. Its IRND designation refers to infrared neutral density: this type of filter is intended to manage infrared light as well as visible light. That makes it relevant when you’re aiming for controlled tones in long-exposure work. It suits photographers and filmmakers whose setup takes a 112mm filter and who need a strong reduction in light. Think flowing water rendered with movement, or a slower shutter in daylight. The 2.4 rating points to a substantial reduction, so it’s a considered tool for a specific exposure problem rather than an everyday filter.\u003c\/p\u003e\n\u003ch3\u003eUnderstanding the 2.4 rating\u003c\/h3\u003e\n\u003cp\u003eA 2.4 optical density corresponds to eight stops of light reduction. In practical terms, that gives you room to trade a fast exposure for a slower one while keeping the same aperture and ISO. The filter won’t choose the shutter speed for you; you’ll still need to meter and adjust for the scene. But knowing the strength helps you plan the exposure before you set up, rather than guessing at how much light the filter removes.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eEight stops is a strong reduction, so this isn’t the filter I’d reach for when only a small shutter-speed adjustment is needed. It makes sense when bright light is the obstacle and you want a visibly slower exposure. The 2.4 rating gives you eight stops to work with: as a guide, 1\/125 sec without the filter becomes about 2 sec at the same aperture and ISO. That’s a useful starting point for giving moving water a soft, continuous look. The 112mm size is a specific fit requirement, so match it to a setup that takes that filter diameter. For milder light control, this strength may be more than you need.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct: Tokina 112mm Pro IRND 2.4\u003c\/li\u003e\n\u003cli\u003eFilter size: 112mm\u003c\/li\u003e\n\u003cli\u003eFilter type: IRND\u003c\/li\u003e\n\u003cli\u003eDensity: 2.4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tokina","offers":[{"title":"Default Title","offer_id":57503626363220,"sku":"TO-CIRND24P112","price":140.62,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.htf-store.com\/zh\/products\/tokina-112mm-pro-irnd-2-4","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
