Mitomo PR: True ND [Blackmagic Pocket Cinema Camera and Infrared Pollution]

“Accurate Transmittance and true neutrality TRUE ND is a clear glass coated with metallic alloy film on both sides. Manufactured under strict quality control, TRUE ND will offer you accurate transmittance and true neutrality. Troublesome infrared will also be filtered out by its flat spectral curve up to 750nm. TRUE ND is simply how ND filters are supposed to be….”

Mitomo True ND fixed neutral density filters – “a clear glass coated with metallic alloy film on both sides” – in densities from 0.3 to 2.1 aka 1 stop to 7 stops.
Mitomo True ND fixed neutral density filters – 4″x5.65″ and 6.6″ x 6.6″ aka 100mm x 150mm and 160mm x 160mm.

Commentary

I have been researching possible solutions for the infrared pollution problem inherent in Blackmagic Design’s cinema cameras which have little to no built-in protection against it, especially the Blackmagic Pocket Cinema Camera 4K aka BMPCC 4K.

So far there appears to be three different most viable solutions – IR cut filters mounted on the camera itself, screw-on IR cut filters to go on the front of the lens and IR plus ND (neutral density) filters screwed-on or mounted in front of the lens.

I have ruled out small IR plus ND filters mounted on the back or camera side of the lens as they are difficult to use and swap without getting dirty when in the field shooting documentary video though they may be more viable under controlled on-location or studio conditions.

It appears that some makers of ND filters do add IR cutting to their filters and some do not, complicating things just a little.

As I come across different brands of IR cut solutions I plan on adding them as link articles like this one.

My preferred IR-cut plus ND solution is either an IR-cut filter on the camera itself or as fixed or variable ND filters on the front of the lens.

As a self-funded independent documentary moviemaker affordability is key but I do not wish to sacrifice quality or portability.
