Me again: was Palawan = Tubbataha? Looks like it to me. Did you like it?

Ok, I think HD cam have less noise in dark, correct?

You can brighten the picture using gain, but it adds noise. I set my auto gain limit to 6 or 9. This is a personal preference as each of us will have a different tolerance to noise. You can go all the way up to +18 gain.

To my eyes, when I shoot underwater with this setting plus the red filter, the brightness looks the same through the camcorder than it does with my own eyes viewing the scene. If I need to brighten the shot, I'll remove the filter.

Ok! This is a good information, thanks. I'll see this setup on the cam, thanks.

Other question about wide angle : I need 80° wide angle minimum, and on the description of wide angles on the net I always see 0.7x or 0.8x : how can I convert that information into angle? 0.8x = 80° ?
thanks

 

[mobula]

I think it is like this:

wideangle of the cam / 0,x = wideangle with the adapter

I would recommend at least 80-90°.

Ok, but I can't find the wideangle of the fx7... I've found 3,9-78 mm for the focal...
Do you have a trade/model to recommend?
thanks

Do already own a FX7? Housing?

There are two possibilities:

1) Housing with good optics

2) Adapter behind Glasport, brands: Century (Schneideroptics), 16x9Europe or raynox. My recommendation is century or 16x9.

 

[Recif]

Yes, I think I'll take the aditech one (http://www.aditech-uw.com/product_info.php?products_id=541) with glasport http://www.aditech-uw.com/product_info.php?products_id=740
Because no "small" wideangle is available for. Only phantom extra large wideangle but can't put a red filter on.
I do not already own the fx7, but preparing to.

This one would be ok?
