Some more photos attached.
I think the UFL is the fish eye lens which is not removable underwater.
I can switch between the UWL & the UCL underwater which is a huge advantage.
I do get some CA as i use the S70 which is 28mm at its wide position without the UWL.
I recommend you get the UWL but you need an external strobe as the internal strobe will lack power. Also the lens obscures some of the internal flash.
