Housing for Sony A7r VI

Hi, my next trip is in March 2027 Anilao. I will need a setup for the A7Rvi. Until now I used Isotta and I was fine with it. But there is no housing from Isotta for this camera until now. I already have the port, Vacuum system and some other parts like Nauticam full frame viewfinder.

Could you recommend a Marelux housing with a port adapter to Isotta? I will only go for Macro with the Sony 100mm. Or is the Nautical housing much better in handling?

What is your experience?

Is there any chance to geht an Isotta housing until March in the case, someone from Isotta is in this forum?

Many thanks

Susanne
