Thank you for viewing. I am selling this because I am getting a new camera. Nikon D850 This is a set of housing & port compatible with the Nikon AF-S VR Micro Nikkor 105mm f/2.8 G IF-ED. [Items] ◆ Housing Nauticam NA D850 S4FG (tax included ¥701,800) with NA Vacuum Leak Sensor System ◆ Port Nauticam NA Macro Port N105VR (tax included ¥85,580) ◆ Focus Gear Nauticam NA-N105 VR-F (tax included ¥36,080) ◆ Accessories Camera fixing plate, hand pump, grease, instruction manual, spare housing O-rings ※ Direct base is not included. [Condition] I purchased it new and used it for about 3 years. I was able to use it without any problems until the summer of 2025. With a reliable vacuum leak sensor system, there has never been any water damage. Each button and the leak sensor have been confirmed to be working. The exterior shows some scratches that are typical of normal use. Also, there is a whitish, hazy discoloration overall. There are no scratches on the port lens. There is almost no deterioration of the grip. The original O-rings for the housing are still attached, but please replace them with the spare O-rings when necessary. There are no scratches on the O-rings for the macro port, but we recommend replacing them with new ones. I have not had it overhauled since I purchased it.
