It can be used to darken bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.

This filter has a 0.9 band of density across its center region. After a hard-edged line of transition, it tapers to a clear area. This design allows the filter to match the sun's position when it is at or immediately above the horizon. The hard-edged line of transition is useful for hard transitions between the sky and land. The filter features a waterproof and low reflection nano coating and comes with a leatherette carry pouch.

Q: 1. Does this fits Tilta 4 x 5.65" Stackable Filter Tray Holder (BH #TIMBT16SFH)?

A: According to Tilta, the Mirage-system supports 2mm and 4mm filters like this Nano IRND 2.1 filter. The issue with your question, however, is that the stackable filter tray holder is not the device you need to hold the filter. You need TIMBT16SFT (stackable filter tray) AND TIMBT16SFH (stackable filter tray HOLDER) to work with the Mirage matte box.

Q: 2. Does this have the scratch resistant coating which was demonstrated at NAB 2016?

A: Scott, these particular NiSi filters do have a scratch resistant coating, BUT, it is not the same as what was demonstrated during NAB 2016. NiSi has a new line of filters with a very strong scratch-resistant coating coming out later this year. That is what was being demonstrated at NAB 2016.
