Sigma 17-70 mm dome

I would appreciate any recommendations based on experience for a dome port (Zen, Nauticam or S&S) useful for the Sigma 17-70 mm (macro) lens.

Thank you.

This lens works well in pretty much everything other than the small 4" dia domes used for fisheyes. So if you have a mid-size to big dome chances are you don't need to buy anything else. But if I were setting this up from scratch I'd use a 170mm optically coated glass dome w/ 5-6cm of extension (depending upon the 17-70 variant).

Ryan,

Thank you. I need a new dome, so I will order a Zen 170 mm in the next couple of weeks.
