Hi ! yesterdat I shot some test with this camera at 30fps and the best resoluc. 12 o'clock midday , sun on top in a swimming pool . Problem : otuside water the image is perfect but underwater, the image comes out very soft ... really really soft kind of out of focus and can't find the focus anywhere ( not near not far ) ...
Talk to a friend of mine, and told me its strange...
somebody knows why?
could be cause of the sun? the water was clear ... the walls of the swimming pool are light blue ...

its not uploaded in the best resoluc, but its aprox as I see it in my monitor..

Here's what they say on their web site about it:

To me that looks like a lot more than a "slight loss of sharpness". But a curved outer surface and the
refractive index of water being higher than that of air would definitely account for the results you got.

There is already a flat glass available from an other company.
