I shoot the 5D mk2 in an Ikelite. It is my 3rd Ikelite housing, and I like the fact you can fully use all the buttons on your rig. I also like the fact you can "see" a flood happening (if it does), instead of the "too late" alarm other housings have. If you keep your seals clean, you'll be fine.

As to lenses, I use the 17-50, a 15mm fisheye, and a 100 macro (all Canon). You cannot fit a 16-35 2.8 lense in the housing (too large of a diameter).

If you go ports on the macro, go with the modular macro port, the focus port (has knob, and useable on other lenses), and whatever else you need.

I also have the large dome port, great for the wide-angle stuff.

Ikelite upgraded to a 4 point lock system on their ports a couple of years ago.

This is not to slam the aluminum ports, as they are obviously very nice. However, you won't feel bad when you upgrade bodies, then have to say goodbye to a $3000+ housing. The Ikelite accessories are also more modestly priced, for what it's worth.

Might be interesting in selling an Ikelite for a 5d2 (am looking at going to a 5d3). Message in interested.

Ah, questions, questions.

On the holder for the Subsee, go single or dual flip holder?

Thanks
