Nauticam NA 5D IV housing with 8.5 Dom positive buoyancy

Hi,

im using a Nauticam housing for a Canon 5D IV, flash trigger and 8.5 Nauticam Dome.

The Lens is a Sigma 15 2.8 Fisheye.

I have a very positive buoyancy. The camera plops to the surface

Do you guys have any idea how i get handle this

My 2 Sea&Sea YS-D2 makes it not realy better....

I have the Ikelite housing with 8" dome port for my 5D lV. I am using a Canon 16-35 F4L lens. I took it for it's first dive in Palau and found it to be very buoyant. I used a couple zip ties to add a two pound weight to the bottom of the housing. While it makes a heavy system even heavier when out of the water, it seemed to really help. I think three pounds might be perfect, but there was no three pound weight available.

Ok, but ikelite and Nauticam are a little bit different

So weights won't work with nauticam? Physics don't change

sure not, but the ikelite housing is a complete other building/construction/material...you cant compare this two housings...

That is complete , Well you know. If it is too buoyant you either need a smaller port or weights. That doesn't change if your housing is made of gold or balsa wood.

Ps depending on how much weight is needed, this tip might be handy.

Put some Z240s on it instead :-) Or metal strobe arms. My Nauticam 5D4 is just about neutral in salt water and negative in fresh.

Or weights. The advantage of adding weight is that you can put it in the right place to balance the housing into the upright position.

Add stick on lead weights which they use to balance the wheels on your car. Fine tune to perfect balance.

I use the stick on wheel weights on the fisheye dome port on my Sea & Sea, as it floats dome up otherwise. They work great. Just cover the bottom shade ring with them.
