I've been diving for years now but am just deciding to make the plunge into UW photography. I want to do make a cheap compact set up to learn the basics before investing thousands obviously. I've done a fair bit of reading already to learn some of the basics.
I already have the Panasonic DMC-TS3. The spec's are here: Panasonic TS3 Specs. It has a cheap ikilite housing which I was hoping to add a moderately priced strobe too. The only thing that concerns me is that the aperature only seems to go from F 3.3 to 5.9 as far as I can tell from messing with the camera and reading the manual. Also, the only way I can seem to change the F-stop is by zooming, In macro mode it seems to always be at F3.3. I am able to change the other settings like shutter speed, ISO, and white balance manually. From what I've learned so far, I'm afraid this will allow to much light in as F8 seems to be the preferred aperture.
I'm wondering what problems I'll run into with these wide apertures, if any, and what other settings could I change to overcome them. Is it even worth it to buy a case and strobe for this camera if I can't adjust this value and I want to learn the basics of UW? What kind of shots will this effect the most, wide angle or macro or both?
