Hello,
I'm a professional photographer but new to underwater. I'm also a PADI certified scuba diver, have been for more than 20 years but every time I go on a diving trip I have to get refresher courses LOL (that's how often I dive!).
I got a soft case to get my Canon 5D underwater (not too deep, to be sure) but found I have a lot to learn and a better case!!
So I'm really learning from you all.
