Has/is anyone using a 1:1 viewfinder on their nauticam housing with a sony mirrorless camera like the a7rv, presumably with the sony viewfinder in "zoom out" mode?

I've seen a post where someone used this on their nikon z series, but interested specifically in a sony unit.

Believe @Alex_Mustard uses the 0.8:1 unit and prefers it. see this video:

I''m sure other Sony users will chime in.

Thanks Chris,

Just watched this.

I have the old model on my A7RV, I guess that's 1:1? It fits and you can see most of it at the right angle...... it's my first viewfinder though so I don't think I can offer much actual opinion on it (didn't want to pay thousands for the new one and potentially find I don't like it) - I found it quite hard to use, but expected that to happen. And I'd probably find the 0.8:1 hard to use too!

The Nikon Z8 (maybe other Z cameras) has a feature that slightly reduces the size of the EVF display. This allows the camera to work with the older Nauticam viewfinders without clipping the display. Works great for me.

Does Sony have a similar option?
