When choosing a housing for your Sony A7r IV, you must first decide on a budget, which would determine whether you get an aluminum or polycarbonate housing. Read more about the differences here.
Nauticam have the advantage of a very robust port system, which can support nearly any relevant lens and many Canon lenses as well using the metabones adapter. Aquatica have a slightly more limited port system.
However, Aquatica includes the vacuum system for a slightly lower price and allows you to choose the bulkhead that will fit your choice of strobes.
Nauticam are generally more available than Aquatica and we can deliver most of their housings rather quickly, while Aquatica take a bit longer to receive, as some of their housings are made per order or in lower quantities.
If you choose to go the polycarbonate route, a big consideration is strobes – NiMAR fully supports Sea & Sea Inon strobes while with Ikelite you can only use Ikelite strobes, or S&S type on manual only. You cannot trigger strobes optically with Ikelite.
