I'm an avid diver and serious amateur photographer, but I'm just starting to put the two together. I'm off for a week of diving in January, and I usually dive one or two weeks a year.
I own both a Canon G9 and a Canon SD800 ... I'm wondering for which I should buy a housing and take with me. I could go either way.
The SD800 has 28mm equiv ... but the G9 shoots RAW, has a higher resolution sensor and has many more manual controls including manual focus, TTL strobe capabilities, among others ... but the wide end starts at 35mm equiv.
Is the 28mm wide angle worth leaving the other functionality behind, particularly as I'm still just starting out?
Thanks in advance for any advice!
