Why don't we merge this group and the other main hm100 group?
I subscirbed both and most of the video published are the same... shall we migrate to the other group? It has more videos uploaded, so it makes sense...
I have a Letus Extreme that I use with the HM100. Initially I purchanced 2 step up rings to attatch to the camera, however since the filter ring threads are recessed on the hm100, that didnt work out well. The best soultion I found is to attatch it to the lens hood since it is also a 72mm thread.
