Ikelite housing for RX-100 and vignettig on WA

[roswin67]

Hi guys,
I've just bought a new and shining RX-100 and I'm thinking to take her with me underwater. I've been using happily for many years a Oly 5050 in Ikelite along with the UWL 100 and macro lenses with a 67mm set. I have also two ikelite DS125.
I'd like to buy the ike housing for the RX-100 but I'm concerned with the vignetting issues. Are they really exist in particular with the UWL100?
Thanks

Inon has two types of UWL100 lens, one of them is dedicated for 28mm focal length, but together with dome unit it can vignietting.
Ask people at bluewater they did some test of the lenses and RX100.
