The Tokina 4x5.65 Pro IRND 2.1 is a neutral-density filter for camera work where you want to reduce incoming light while keeping those exposure choices open. Its IRND designation also makes it relevant when infrared light may affect colour with strong filtration. It suits cinematographers and video crews working in daylight or other bright conditions, especially when a consistent exposure is important across a sequence. The 2.1 rating gives substantial light reduction, so this is aimed at situations that call for a strong fixed density rather than a small exposure adjustment. It’s a focused tool for planned setups, not a variable filter for changing conditions on the fly.\u003c\/p\u003e\n\u003ch3\u003ePlanning exposure with a strong ND\u003c\/h3\u003e\n\u003cp\u003eA dense filter is most useful when you decide which part of exposure you want to preserve. For motion work, that might mean keeping your chosen shutter speed and adjusting the iris or ISO to compensate for the reduced light. Set your exposure with the filter in place, rather than relying on a reading made before fitting it. That keeps the filter’s effect in the exposure calculation from the start.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003e“Will a 2.1 density make a visible difference to exposure?” Yes—it cuts light by about seven stops, so it’s for situations where you need a substantial reduction. For example, if an unfiltered daylight reading calls for 1\/6400 sec, seven stops of reduction brings you to roughly 1\/50 sec at the same aperture and ISO. The 4x5.65 format is a large rectangular filter size, suited to setups built around that format. I’d point a cinematographer toward it for bright exterior work where maintaining a chosen shutter speed matters. One thing to bear in mind: 2.1 is a fixed density, so it won’t give you fine, continuous adjustment as the light changes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Tokina\u003c\/li\u003e\n\u003cli\u003eFilter format: 4x5.65\u003c\/li\u003e\n\u003cli\u003eFilter type: IRND\u003c\/li\u003e\n\u003cli\u003eDensity: 2.1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tokina","offers":[{"title":"Default Title","offer_id":57564059402580,"sku":"TO-CIRND21P4X5.65","price":199.15,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.htf-store.com\/it\/products\/tokina-4x5-65-pro-irnd-2-1","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
