Ok I've finally got my pics up, been playing with the G7 + Ikelite + UWL-100 in Sipadan for a week. No strobe though, and unfortunately it was very overcast for the first 3 days of my trip so the light wasn't great. Things did brighten up towards the end though. Was still an amazing trip though, if you haven't been to Sipadan you must go immediately!
Here's my gallery:

The vast majority are with the UWL-100, the nudibranchs and grouper and night dive shots aren't though. There's quite a few panoramics too which are stitched together from about 5 shots each, WA portrait. A few pics have been cropped slightly and I played with the red balance & contrast a bit too.
I started off on manual but after missing some good shots switching between aperture and shutter speed I decided to stick with TV mode. I set C1 to 1/50, underwater white balance (I tried setting it manually using a white slate but I thought the underwater setting was fine) and tried to shoot in ISO 100 or 200, but when it was really gloomy I crept a bit higher.
All in all, I really like the set up and kept the WA lense on for most of the trip. There are a few issues with it though. Even with no zoom, the edges are sometimes a bit blurry. This can be solved by cropping your pics but that's not ideal. If you start to zoom the blurring gets worse quickly so basically forget about zooming with the WA attached. This means you have to get really close up.. ok if there's millions of turtles about but more tricky with fish. Also forget about using the built in flash with the WA, even with the Ikelite diffuser. I'm really interested in getting a strobe to use with this lens, preferably one with a really wide angle of coverage and hopefully just the one. Anyone got any suggestions?
I'm happy with the housing although one one dive things got a bit foggy for no particular reason. On another dive the mode select dial stopped gripping (some moisture in the I presume) so I was stuck in whatever mode I was in. This was despite having loads of silica gel on board. Sometimes the buttons are pretty stiff and I came out with dented fingers after a few times. Also, after taking a shot, you can half press the shutter to get of review and take another shot quickly (e.g. if a shark is swimming right towards you). I found this hard in the housing and ended up triggering another shot by accident on the half press then being stuck in review again and missing the shot i actually wanted. Minimum review time is 2 seconds, I wish you could change it to 1.
Anyway, a great first trip with the G7, I certainly learnt a lot (this is my 1st U/W camera too). Can't wait for the next outing. Got some video I took with the G7 which I'll try and edit and stick on youtube.




p.s. yes i was using the short port
