Looking at the Hero Session and wondering if the extra $100 for the Hero5 Session is worth it? The only feature that interests me is the image stabilization. There's a few videos that make it look like it is effective like this guy: https://www.youtube.com/watch?v=ri79GDP77XI but nothing with aggressive downhill riding.
Does it work good enough to be worth the extra $100?
Well, the stabilization is surely decent. But not worlds apart from the Session. You may want to buy a three axis Gimbal instead. But if you wish to play in the rains, yes the little stabilization the Hero5 brings may be helpful.
