Hello, I've owned an Isotta housing for my Nikon Z8 since last year and I'm very happy with it. Before that, I had a Hugyfot housing. What I appreciate most is the ergonomics; all the controls are perfectly positioned (I have small hands and I was sometimes uncomfortable with my old housing). It remains compact despite the size of the Z8, with double seals, a vacuum system, and a locking mechanism and the price... It's compatible with Nauticam, so I use the 24-50mm lens with the WWL-C. Elisa from Isotta is very responsive and answers any questions quickly. However, it's important to clearly define what type of flash connection you'll be using. Personally, I didn't get the Isotta trigger to mount a TRT Electronics Smart 3. Upon delivery, the housing was assembled with LEDs and cabling incompatible with the TRT. I had to order compatible parts and replace them. Isotta offered to make the modification at the factory to keep the warranty, but this would have meant returning the housing I had just received.
