Why do you say it does bad? My video (shot in R-5) seems ok and shows no vignetting on my video???
R5 in the HD1 is 127 FOV and its the only mode that doesn't vignette with the drop in type lenses using the HD1 camera, this is the same with the HD2 as only 1080P medium 127 and narrow 90 along with medium photo mode will be fine with drop in lenses.
All other modes will show vignetting, so you dont get to use the full 170fov fisheye lens underwater with those types of fixes. If you only shoot in r5 mode with a HD1 then you will be fine with that lens.
