Hi all I've tried the search feature but I can't find an answer. Has anyone tried the 50mm zoom lens from ragecams http://ragecams.com/shop/50mm-mega-pixel-lens-installed-hero3-black-p-582.html on their H3-2D? I need to zoom + gimbal + osd + some kind of recording the altitude. I think DVR on the fpv gear recording the OSD output would be fine... Regards, Scott.
