Ah yes, Aldo....a gifted photographer for sure...met Aldo on a recent trip and we compared housings. I also was wondering how the dome port handles the cameras with a variable I.O. I had thought this just was not possible to do.
I have been using the Gates housing with B.Cranston and we are quite a bit larger and a flat-port. I would post pics, but seems i have to have them on the web before posting.
