Subal ND70 + Sigma 12-24 + SWB dome

Hi Guys:

I was thinking of buying a Sigma 12-24 Lense for my Nikon D70 + Subal housing.

Could anyone provide some feedback about using this lense with the Subal SWB dome port.

Thanks

Hi,

I have this lens, but I use it with a Seacam housing but I'm sure the same considerations apply. I use the largest dome port I can get, as for a lens this wide, the larger the dome port, the less blurring in the corners you will get.

The front shade of the lens (attached) is too large to fit through subal extension rings.

Is there a reason you need full frame? If not, your money might be better spent on the Nikkor lens, or waiting for the smaller sigma DG zoom...

Good catch Ryan. Does the 14mm Sigma f2.8 fit through there?

Cheers

Will the Nikkor 12-24 go with the SWB dome? If so with what extension rings?

The Sigma 12-24 will work with Subal Extension Rings. Ryan is correct that the hood will not pass through the extension ring but the lens will pass through.

Here's the installation procedure:

1: Install the camera body onto the tray and place in housing

2: Install the Extension Ring onto the housing (40mm w/ 8" Dome)

3: Pass the lens through the extension ring and attach to the camera

NOTE: This is done blind so you really need to be comfortable with lens installation.

4: Install the Dome Port

In most cases a Zoom Gear is not necessary as the Zoom Drive on the housing will couple right against the Rubber Grip on the Lens Barrel.

I completely agree with James, you will get much better results with the 8" Dome Port with this lens.
