Hello

I am searching for any feedbacks and/or advices concerning the use of canon 8-15 with a seafrogs housing.

In fact, it seems that seafrogs now allows to use Sony fullframe with canon 8-15 with either 6 and 8’´ dome ports V7.

Anyone has any feedback of this setup?

I don’t see other cameras in their port chart to use with this lens.

For APSC, unfortunately ,I still don’t see the tokina 10-17 in the APSC port chart…Someone already tried it?

Thank you

Seafrogs aluminium or plastic ?

Where did you see this?, I find Sea Frogs documentation for this hard to follow. It seems they have two different ports with built in extension for their plastic housings so don't really attempt to precisely position the lenses behind the dome. The citeria seems to be just make sure it doesn't vignette. I see they have extension rings listed now, but don't see them mentioned anywhere in their lens charts.

On the 8-15 on full frame - it's either 8mm circular of 15mm diagonal fisheye so unless you want circular fisheye you don't need a zoom gear and if you can use it at 15mm without vignetting it's probably as good as you can get in this system. On the 15mm fisheye, it's probably a bit short for your stated interest in big animals, particularly sharks and rays where you can't get quite that close.

And in the comments they said that no vignetting at 15mm with the setup used.

And a quick video on youtube showing that the buyoncy seems good :

Concerning the fov, I currently have a Sony 16mm with fisheye converter so is should be equivalent to 10mm fisheye on apsc.

So if i m not wrong, it should be the same fov as the tokina 10-17 at 10mm on apsc or the canon 8-15 at 15mm on full frame. Is it correct ?

I agree that i don’t need zoom gear for the canon because i would use it at 15mm.

I also have the Sony 10-18 with the 7’´ nauticam dome port and i used it just a couple of time because i prefer the fisheye fov.
