Tokina 86mm Pro IRND 0.9 Filter

The Tokina PRO IRND 0.9 Filter is an ND filter with a 8x filter factor that provides a 3 stop exposure reduction. It's 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the colouration of the image and are ideal for pairing with other filters. The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, colour casts can occur when photographing darker subjects that require increased exposure times. To provide a high level of neutrality across the visible and infrared spectrums in order to eliminate colour casts and ensure cleaner, truer blacks, each glass surface includes one layer of ACCU-ND Vapour Deposition coating. Tokina?s Accu-ND Technology redefines the combination of IR and ND filtering Professional-Grade Optical Glass Avoids the need for white balance adjustments, colour corrections, stops IR pollution & colour shift Metallic ACCU-ND coating Available in the following sizes: 82, 86, 95, 105, 112, 127mm diameter, plus 4x4" and 4x5.65...
