So yeah, I was having a though about that it shouldn't be that difficult to make some kind of adapter for regular camera filters for the CGO camera. But I haven't seen one anywhere on the net. Have any of you though about designing one? Just the regular threaded ring with clips instead of the ready made one with the glass already there. I really have a hard time justifying €60 for a bunch of filters that don't fit on my other camera(s).
