#DIYgearchallenge DIY Variable ND filter adapter

Hi guys,

I had an variable ND filter laying around which I didn’t use. So I decided to make me a adaptor for my insta one R.

And this is what it looks like.

It’s always better to use what you have instead of buying new stuff. And also I think there is no variable ND for the 4K mod.

The whole prise of the setup is around 30$

20$ for the filter

10$ for the step down/up rings
