What about the diameter of the lens itself, the rear part that fits the magnet. Is it any larger than 13mm?
On the rear part of the lens there is a thin ring (diam. 13mm) similar to the one you see on the cameara front. Next is cylindrical diam. 14.5mm / length 2.5mm - then diam. 16mm / length 3mm. Maximum diam. front of lens is 20mm / total length of lens is 16mm.
Hope you are able to fit the lens on both your cameras! I like to put it on my planes as it makes the movements look smoother because of the wider angle of view. It is not GoPro quality, but at least you don't have the irritating GoPro bending horizon..
