I am off to dive a large wreck. Baggage restrictions limit me to a single housing.
I wanted to use my D700 and 16mm for some natural light/high ISO shots.
I'm told there is also some macro life now on this wreck.
I have a DX outfit with both dome and macro ports but no macro port for the D700.
I have tried my 60mm macro lens and it doesn't foul the dome port of the D700 housing.
So...
Has anyone tried to use a macro lens behind a dome port? The macro lens is so close to the port I have a feeling it won't see the virtual image and may look straight through, a la flat port.
Full Version: Anyone tried this?
Hi John,
Will be absolutely fine as long as you don't need to go macro-macro. Good down to small frogfish/ornate ghost pipefish size. Tiny nudibranchs, shrimps etc - the dome will be a limiting factor.

Wonderful, isn't it - Wetpixel? Thanks.
I've shot clown fish with a 100 macro behind a dome port - the only difference that I could detect in the files was that the marginal chroma needed different correction from normal - if you bother!
Hi John,
I've used macro lenses behind dome ports for ages. Starting with a Canon 50mm and F1n body in an Aquatica housing in the mid-80's. I still use Nikon's 70-180 Micro-Nikkor behind a small dome almost as often as I use it behind flat glass. You get a wider angle of view and don't get quite as much magnification. Example: With my 70-180 I can focus down to .75x at minimum focus. With the small dome I can only get to about .4x. With the dome I can shoot larger, grouper size fish, with less water distance. So the dome changes the size range of critters handled most easily. In effect, making it like I have two different lenses. Another advantage of using a macro lens behind a dome is since you are focusing on a virtual image that is much closer to the dome for distant subjects, the lens focus point changes less between infinity and much closer subjects. And because of this the auto-focus is noticably faster.

They were right!
I needed to photograph some computer displays at depth. I used the 60mm Macro behind the dome port of my Hugyfot D700 and the pics are sharp as a tack.
Here's a little octopus that I met on the way back up. Not extreme macro but good enough 2:1 anyway.

Which dome port; 128 or 174?

Funnily enough, I took the D700 on the trip because I wanted to photograph the wreck of the Don Pedro by natural light using high ISO settings and the 16mm Fish-eye but the visibility was so poor I needed to use flash anyway, just to get some contrast. I could have taken my DX camera set-up with dome and macro ports!

Well boogers! I am trying to find the post about using a macro lens (50/60?) in a dome port on a black water dive. I want to set up a Nikon D80 with the the older 60 mm macro in a Nexus housing with a small dome port. Fully extented, the 60 mm lens is well into, but not touching the Bare dome port (for Tokina 10-17, has about 38 mm extension) with a 20 mm port extension. Since the lens will focus on the virtual image, should I use a longer PE?
Does anyone know the link to macro with dome post? I think is was a blackwater dive.
TIA,
Bob
