Yes, the 80A is not a red block filter, but a color correction filter. It
needs to let pass some red light in order to work correctly. If you use it
to correct "B" light to daylight, you need to block a lot of red light, but
not all, or you will get no reds in the final image.
>- - The 80A might not block near IR light as much as the visible red light.
It can be true, but I doubt it.
