GoPro to SJ4000 color filter converter

This is a converter from GoPro size colour filters to SJ4000 camera size filters.

I bought on Aliexpress diving lenses that where described as GoPro/SJ4000 compatible. When it arrived... well they where only GoPro compatible.

The most logical way out, was to create a converter - but this would make filter so far from camera lenses, that it frame would be visible on recording.

Luckily, this filters can be easily dismantled in three pieces

• base, that is attached on GoPro underwater lens cover
• top part, that is keeping filter in place
• and the plastic, colour filter

I've prepared replacement for first part - base - that is SJ4000 camera compatible (mine is plain, old SJ4000 - no wifi etc), and you can (without any modification) use filter and top cover from original part.

That's it :)
