Do i need a extension port for my S&S setup?

Hi Guys,

Recently, i just acquire a Kenko PRO 300 AF DGX 1.4X teleconverter to give CFWA a try. However, i was wondering if i can just use the teleconverter with my existing setup without adding any extension port.

Currently, i'm using Nikon D300 + 10.5mm fisheye lens housed in a Sea&Sea MDX-300 + NX Fisheye Dome port setup. Does anybody have any experience for similar setup like mine? Hope someone could advice. Thanks in advance!

Cheers,

Cephas

When you add the tele-converter you need to add a 3/4" or 19mm extension or get a longer port.

Thanks for your reply Bill!
