Anthis Nexus port mount

Hi,

have just bought a used Nexus house for my Nikon D80.

What is the difference between M4, M5, M6 port mounting? can I use an M6 port on a house that is M5 port mount?

Mats

Hi Mats,

welcome to the wonderful and confusing world of Nexus!

Here's their Port Mount chart that shows which mounts came on what housings. They do have various adaptors so you can use

say an M5 Port on a M6 housing, like I am doing myself. I'm not sure if there is a M6 port to M5 adaptor though. Unfortunately it

is hard to get clarity on some of the detail on-line as the Nexus site is in Japanese and Goggle does a very sketchy job at translating.

Have a look around as you can often pick up M5 ports 2nd hand, in fact I'm sure Ryan at Reef could help you with some.

Cheers,

Jim.

The ID of the M5 is 100mm, M6 is 108mm & M4 is 116mm.

Best to stick with the right size port. Some ports will not work with the adapters.

Thank you for all your answers!

What is the port I should use with the Nikkor 14mm 2.8 ED? Is it the same as I use my Nikkor 10.5 mm? Have not double checked but I think it is M5 on my D80 housing.

Hi Mats,

your D80 housing could be either M5 or M6 but simple to check. Did you see the M5 60mm port in the WP classifieds ? Perfect macro port for green waters.

Hej Mats,

The FP170 and the FP230 ports are recomended for the Nikkor 14 mm (114 deg. AoV). The FP120 port for the 10.5 fisheye is too small. I use the FP170-5 (M5) for the Nikkor 12-14 with 40 mm PE and +4 diopter. The "-5" indicates an M5 size port.

I have a FP160-5 dome as it's clearly an M5 port mount.

What lenses are the FP160-5 dome intended for?

Hi Mats,

the Nexus FP160-5 dome should suit the Nikkor 14mm 2.8 ED with the addition of a 20mm extension ring (PE20-5).

The next question would be is a diopter required with this combo for sharper corners? Time to jump in a pool for some tests maybe.

Cheers,

Jim.
