Nikon 17-55mm f/2.8 DX and a Sea&Sea housing

I would appreciate some advice on using the nikon 17-55 with a Sea&Sea housing (MDX-D300). Sea&Sea themselves haven't included it in their system charts as an option (which is a bit of a surprise to me).

Can somebody tell which port (and extension rings) they are using?

Any help is welcome.

Regards,

Peter

I'd recommend stacking an extension ring 40 & an sx extension ring in most domes, and a +2 diopter.

thanks! So you do recommend using a diopter as well?

Would it make a difference using the large fisheye domeport or the smaller one?

I've only shot it in the 200mm Zen dome, and that was with a +2 diopter. We've had customers use it in the Optical Dome Port w/ +2, but I haven't seen the results.

Just as a reference point, I use the 17-55 with my Nexus FP170 port, which is about 6.75" dia. +3 or +4 diopter depending on subjects I'm looking for. +4 seems to produce a slight sharper image in the corners, but lens will not focus at infinity at the 55mm end - good otherwise. With a +3 it will focus throughout the entire zoom range.

Thanks Ryan and Jim for the inputs!
