I'm using D700 & 17-35 with Zen 230 port but I still have problem with soft focus around the edge of my frame. Do I need diopter to solve the soft focus?

Unfortunately, if I understand the thread properly, that might be as good as it gets. The 16-35mm, despite being a less well-specified lens, seems to work better behind a dome.

By less well specified, do you mean just the maximum aperture? In other respects it is probably better 'specified' particularly for digital. Remember the 17-35 was developed in the film days. The reason the 16-35 behaves better behind a dome may have to do with the way the light is collated more specifically for digital sensors. I'm not sure I see the real differences topside between the 2 lenses, and in fact gave my 17-35 to a friend and don't miss it. The 16-35 also has VR.

Basically, although the construction of the 17-35 seems a little more rugged, too. You're right about the rest, the 16-35mm seems to be the one to house, even if it's not without problems and needs a big dome.

Does anybody have experience with the Sea@SEA D800 housing and the best extension to use with the S&S fisheye domeport for the nikon 16-35?

Hi pdemaagt,

I have heard two person who use 40mm + 40mm extension rings behind the big S&S fisheye 240 domeport. If I am not wrong S&S have also aproved this combo know! The pictures I have seen with this setup is perfect!
Anyone know if someone use Sea&Sea Optical domeport and the sigma 15mm fisheye direct on the MDX800 housing without extensions? Would be nice if it works without vignetting.

I tried an optical dome port with a 20mm extension and the Sigma 15 on a Nauticam D800 and it vigettes the sunshade pretty well. I think that dome is going to be too small for it.

Thanks!!
Practically it would mean I will add the Extension Ring 40 and the SX extension ring.....I don't have two 40's :-)
