If you want to know for sure, point the camera at something and lock it off with the tripod.
Take a light reading, then put the adapter on, & take another reading.
Check the manual for this (I've used the Canon & the Nizo UWIII, so I may be mixing things up here...) but the other thing is, you need to enable "macro" setting, and actually pull focus to the surface of the adapter. You're actually macro-focusing on the adapter glass.

Also, Canon recommends you shoot wtih an f-stop of 5.6 or better (e.g. 8) and this is good advice. Shooting wide open results in soft images. I have this adaptor for my 814XLS and I get soft images if I am not at 5.6 or so.

On the other hand, the wide angle attachment gives the camera auto exposure meter more area to determine the exposure setting, but does that make the auto exposure meter more accurate versus normal wide angle mode?
As for f-stop minimum's, I find that wide open usually does makes the wide angle image softer on my Eumig, but I have been satisfied with a minimum of a 2.8-4.0 split, but that is for a Eumig, so perhaps it's higher for the Canon as Rick and Matt suggest.
However an f 4.0 probably would render a decent result.
