High Def Filters
 
I've seen filters advertised as High Def filters, like the Formatt High Def filter I saw on b&h:

I think Tiffen has a filter set advertised as 'HD'. Just wondering if anyone had tried these, and genuinely found them better for HD cameras than other filters?

I could be totally off, but for the last ? years, filmmakers have been using good ol' regular filters. Not sure what about the glass may have changed to make them up to HD standards. Good glass filters are good glass filters. 6x6's seem to be fine for 35mm scanned at 4k, not sure why you would need better for HD. I understand that lenses for small format cameras must be far sharper than those lenses for 35mm, but I can't see why filters would. Sounds like marketing to me

Hi Def filters, at least the tiffen one aren't a new line of filters, for instance, there won't be hi-def polarizer filters. What hi-def filters are is basically a tool to limit the sharpness of HD, I think. If you watch second unit TV's filter episode they go over it

If these same filters are good enough for a 4x5 view camera, it's certainly more than enough for any digital format.

Tiffen has a set of "Digital Diffusion-FX" or something, which is basically their Gold or Black Diffusion-FX filter with the pattern of gold or black dots removed, since the deeper focus of some video cameras risk having the pattern come into focus. The removal of the dots just means that the filter has a slight contrast-lowering effect besides the softening.
