Once again - G2 v CP5000; how is the G2 macro?

Looking to get into UW digital, don't have any digital equip. yet. Figure it's best to wait on the DSLR technology for awhile - by the time I get MY ability up to it the technology will be much more advanced anyway.

So, I've been reading lots of past threads on camera choices. I think I've narrowed down to G2 and CP5000. As I see it, the G2 has the CP5000 beat on most counts except the macro (that add on lens for the CP sounds kewl). I do most of my diving in the Pacific NW - cold water and lots of macro. Except for when the wolf eels and octos are out - then we're all about wide angle! So the Nicon lens that is highly flexible sounds very intriguing for that reason.

Can anyone point me to some small critter stuff taken with the G2? Are the add-on lenses changeable UW (so I could still switch back and forth on the same dive)?

I have a G2 / Ikelite housing set up with a DS-125 strobe. I have no complaints about the macro capabilities. You can see a sample of some of my shots at http://cosmiccontamination.com/jsparks/index.htm

Keep in mind I am still somewhat of a beginner at this stuff. I just got my INON WA lens for the housing, but I haven't been able to use it yet.
