Great video ! I like the clean backgrounds.

It is beautiful to see them 'graze'.

 

Do you have an additional wet lens, or only 100mm macro ?

I was persuaded to have 8'' domes as the previous owner had told me. Hugyfot doesn't manufacture any 8''.

 

I already told you so ;) :

 

I think fisheye port 6.608 is 174mm, being 6.85''.

Which brand is your 8'' dome port ? Does it require an adapter ?

I think vignetting in this topic is more about the position of the lens

to the dome, rather than the diameter of the dome port.

 

When the lens is too far in (example below), you will have trouble

focusing. When the lens is too far out you will get vignetting (and

probably trouble focusing too). If an adapter between the dome and

the housing is used then your nodal points might be off.

Why the disapproving smiley face ? Just put on the 7'' dome and

go diving !
