The 82mm ExpoImaging ExpoDisc 2.0 White Balance Filter V2 features 18% calibrated light transmission for ensuring correct exposure and white balance settings while shooting and editing. It attaches to lenses or filters with an 82mm thread via a button-activated spring attachment. This is even compatible with low-profile filter threads. Also, the ExpoDisc 2.0 V2 can be used with smaller lenses by simply holding the filter in front of the lens.
The ExpoDisc 2.0 V2 can also be used to dust map a camera sensor due to the neutral image it creates.
Each filter is made and calibrated in the USA for accuracy and includes a lanyard and carrying case.
