This is the Nauticam acrylic semi-dome port for the Panasonic Lumix 7-14mm f/4.0 wide angle zoom lens. No extension needed as it is designed specifically for that lens. This is a nice lightweight port that fits any of Nauticam's Micro 4/3 mirrorless housings. It is in very good condition. There is a light 1/2" scuff on the outer edge of the port that does not affect photos at all that can be polished out with Novus. In fact, I'll do this for you prior to shipping and you will not know it was ever there. It includes the neoprene port cover as shown in the photo and it will ship in its original factory packaging. However, I do not have the back cover as it was not supplied from the dealer.
Selling because I have upgraded to a Zen glass port for this lens.
Original MSRP for this port is $500.
Selling for $300 + shipping
