I didn't see it advertised anywhere but looking on Nauticam's website:
they are making a housing for the ZV-E1. I was interested to see if this was going to happen as the specs on the camera area great for video (FF 4k 60p with 5 axis stabilization) and it is a small camera body leading to a very cost effective housing. Seems to fill the niche of the A7c with all the spec of the A7sIII but at a fraction of the price. The challenge is the slow flash sync speed of 1/30th making it really only a video camera for underwater work that would be superb and small.
This plus some of the current and new nauticam optics could be a just great compact video rig. Since that is an oft discussed topic, I thought I would share.
