This is my first post here.
I bought a Canon S90 and Ikelite housing in 2010, but I haven't had much chance to use them. So I am still very new to this.
From my readings, I have my eyes on Inon UCL-165M67 and FIX UWL-04.
My Ikelite housing has a 67mm port, but I'm thinking of getting an adapter ring that will allow AD lenses to be mounted onto my port. Something like this http://www.bristolcameras.co.uk/p-10-bar-67mm-to-ad-mount-adapter.htm. My main goal is to facilitate easier lens changing underwater.
My questions are:
1. How do I mount a FIX UWL-04 to the now AD port?
2. Will the added distance change the capability of the UCL-165 and the UWL-04?
4. Is it worth changing to AD lens? Or should I just stick to M67?
5. Are there better alternatives (in terms of IQ) to UCL-165 and the UWL-04?
