This K&F Concept 82mm Gold Diffusion lens filter is fabulous quality, just as all glass I have ever had from K&F Concept is.

I am a hobbyist photographer and only occasionally dabble in a little video and prior to being given the opportunity to try this filter, have only experimented with electronic film LUTs in post.

Having given this a try, the results are certainly excellent and quite probably better than using post processing filters as I have in the past, however I do feel that to my untrained eye, any discernible difference unfortunately does not warrant the cost of the filter, particularly as if I want to use different lenses, I need a different step up ring for each one (I decided to go that route rather than buying multiple filters to fit each lens).

The other issue is of course that if you film with the filter on, the effect is baked into the footage, so if you want to repurpose your footage or decide you don't want the gold diffused effect, then you're stuck.

However, if you know for certain that that's the look you're after, want the look done very, very well and aren't planning to swap lenses all the time, then for sure, you will not be disappointed with these K&F Concept filters. In my opinion, they are as good as you get.
