This extension ring can be used to extend the basic macro port so that a 105 mm macro lens can be used. It is a very common ring and I used it with my 2004 vintage Sea and Sea housing to extend their 8 inch dome for use with a Nikon 12 -24 mm lens. Please refer to Sea and Sea's lens and port information to identify the correct ring sizes for their latest housings.
I will sell the ring for $170. It is in mint condition. If interested, please contact me at jimirak9@aol.com.
I have attached a jpg file showing the ring.
Only USA orders and Paypal payments please.
