Thanks Rebecca,
The Fathom 90 is a bit too wide for macro work. The flip-out macro lens does not work with the Fathom 90. You can zoom in with the Fathom 90 but it will still be wide for real macro work.
So, I tend to decide on the port to use before the dive. For night dives, I definitely use the standard flat port and then can use the flip macro lens plus camcorder zoom to get some good macro shots. For low-vis dives, I will follow the same strategy. See http://www.peterwalker.com/peterwalker.com/Seahorse.html
But, if I am expecting clear water, big creatures, or a shipwreck, that's when the Fathom 90 is perfect. So, when I have the Fathom 90 on the housing, I don't look for tiny stuff.
Of course, you could argue that having the flat port on all the time gives you the versatility for different size critters from whale sharks to tiny shrimps. But the Fathom 90 is so good at bigger vistas, that I'd miss it underwater. See http://www.peterwalker.com/peterwalker.com/WhaleShark.html
Even in my normal (not underwater) photography, I will follow the same strategy of using either a telephoto, normal or wide-angle lens for a whole shoot. I find that my mind gets into a groove with a particular focal length and that lets me see the images better.
What kind of video do you plan to shoot?
Regards
Peter
Thanks Peter, this is really helpful to know.
As for my video plans, I'm going to keep learning a bit more on my HC7 setup and will use that for my upcoming trip to the deep south Sudanese Red Sea next month. It's a bit frustrating though, because I broke my remote monitor, cannot get a replacement (phased out long ago) and so now I have to look through the little spy hole on the back of my housing to get any feedback on colour, composition, focus, exposure, steadiness, etc. Not a great way to work on my skills as I have to wait until I'm out of the water to see my mistakes but guess I'll have to deal with it.
I figure I will have bought my new set-up prior to my March 2012 trip to Indonesia (Triton Bay, Misool, Halmahera), so I want to have the appropriate equipment for that sort of diving - it will be predominantly a mix of macro and reef shots and maybe some random blue water shots if any big stuff shows up.
It's going to be a huge outlay of money (for me at least) for a new housing and camera so I wanted to determine the best strategy for a lens. Apart from the big annual trips, I'll be diving locally in and around Sydney which, as you may know, is typically 10 metre visibility, relatively green water and a good bit of macro life.
From what you are saying, it sounds like I would be okay for a while with the standard port and the flip macro (though I do have dreams of seeing my first whale shark and being ready to film it). I've scheduled a trip to Socorro for Feb 2013, so I figure that I'll need a wide lens by then. I think I will definitely need a red or orange flip filter up front (can you have both a macro and a red filter in the new housing at the same time?) as I often like shooting without my lights when diving in Sydney.
