my 1st post. I have just purchased a tokina 10-17mmFE for my ikelite D70rig. I have a 6" ikelite port for my Sigma15FE which can be used with the tokina if the shade is removed. What impact will the removal of the shade have on my photos. I will purchase the 8" port if there is an advantage. Any opinions?
I have 2 DS125s with standard 6" arms. i was going to purchase 2 x 8" bouyant ultralight arms. opinions? What will the bouyancy of the system be like with the bouyant arms and 8" port? my current rig has left me with a tired arm on long dives.
all help appreciated

Without the shade you'll really have to be careful on your strobe placement, especially with on 6" arms. 2x8" arms will be better, but remember to keep the strobes back from the plane of the lens. The further back the lesser the chance of blowing out the corners of the shot.
The buoyancy arms will help a little, but you'll probably still be quite negative.
Also, watch out for internal reflections off the lens body. Maybe someone else can comment specifically about the 10-17, but my 10.5 has a gold ring around it that will give nasty reflections off the inside of the port if I don't blacken it.
Hi and welcome.
The 6" port is a bit of a handful without the shade. You will tend to get unwanted reflections and flare creeping in when you least expect. It works but you will have a tough time. I seemed to get a lot of reflections from the join between the dome and the body with mine - And the image was pretty soft at the edges.
From memory the Ike port for the has a stand off but I am pretty sure that at the wide end the Tokina will be not wanting it - or maybe you have one of the new design with interchangeable sections.
Anyhow FWIW I have found the 8" dome in comparison is a joy. And it will work with the sigma (which is a great lens ).
