UWL 04 vs UWL 28m 52

Hey, I got canon S100 and Ikelite Housing and still confused to decided to buy Fisheye UWL 04 or UWL 28 for ultra wide (weitwinkel) (weitwinkel) angle,

Here the spec

UWL 04 has 130° field of view at 0.42x magnification and Diameter 157mm x 92mm

UWL 28 has 168 degree and 0.41 magnification and Diameter 126mm x 85mm

From the spec UWL 28 has wider field of view but smaller dome diameter. I saw from the sample photo on the web, UWL 04 has wider FOV, and I think with bigger diameter of dome can make better split shoot photos, what do you think??

Anyone have been try to compare both of them with canon S100??

Hope anyone can help me, thanks for your respond
