I am planning to add a secondary camera - a modded gopro with a 100°FOV (narrower than stock) lens - to my gear.
To avoid the flat port issues, I am seeking a wide converter - first to provide nice corner IQ then to restore FOV.
Which wide converter shall I try? Inon has a gopro-specific unit (UFL-G140) but that is only available with SD-bayonet
which seems to be impossible to mount on my 3rd party aluminium housing. Besides, the UFL-G140 is obviously designed
for the stock lens, I don't know what it would do with a narrower one.
