Tho the 3D lens I had in the video did have red/cyan colour plastic over each lens... It may have been in the 1%. Really, Did not know that.

It's great to see all these lenses lined up side by side. One small correction: The "old 2perf 35mm 3D cinema lens" was not fitted with red/cyan lenses. It was fitted with linear polarising filters. It is a common misconception that the 3D movies in the 1950s were red/cyan anaglyph - but in fact 99% of them were polarised. A lens attachment isn't required for anaglyph 3D projection. Nice work!
