Tokina Announces Cinema IRND Neutral Density Filters
From Kenko Tokina USA:
APRIL 13, 2015 – Kenko Tokina USA, Inc. is pleased to announce the Tokina Cinema IRND neutral density filters for cinematography.
The Tokina Cinema IRND filters use ACCU-ND technology to yield a truly neutral color balance that will not add any noticeable color cast to your footage. This series was created specifically for the cinema and HDSLR video markets.
The Metallic ACCU-ND coating on the IRND filters do not color shift as you move from one density to the next, a common problem with almost all other series of neutral density filters. Now you can set your white balance once and have the same color balance even if you need to change filters due to changes in lighting, or have multiple cameras with different strengths of filters on them.
The ACCU-ND metallic coating also has the added essential benefit of accurately controlling and suppressing infrared (IR) light so color fidelity is maintained. This is important as IR can add its own color cast when recording outside and manly other IR filters on the market add their own color cast that can be difficult to correct in post production.
The IRND filters use an exclusive clear optical glass that has a metallic ACCU-ND coating bonded to the surface of the glass to create the neutral density affect.
The Tokina IRND series has round filters in common sizes from 82MM to 127MM and strengths from one stop (0.3) to four stops (1.2). The series also has two square mat-box sizes that are available from one stop to 7 stops of light reduction.
