I've been thinking about adding MFO1 and/or MFO3 to my collection. Also likely to want to move to the new sony 100mm macro. In researching these additions, I found Edward's comments here. I would be really interested in hearing about new Sony 100mm macro owners' experiences with the MFO1 and 3 and whether Edward's comments about the wet lens and the functional changes to the older Nikon and Canon lenses hold true for the new Sony.

Thank you.

Still studying my new housing. Can anyone help me understand what this blue lever/button that con-rods to the back of the housing and presses on the small microswitch adjacent the flood protection switch? I know the microswitch turns off the flood alarm, but what's going on with the blue button? Is it so you can quickly dump the port if you have a flood (and you're out of the water), keep the camera facing downwards and mute the alarm without having to fully disassemble the housing?

Yes. Interested to see if @Yorkie88 has this turned on and if its still cropping his viewfinder slightly.

@Yorkie88, is your a7r5 in zoom out mode?

Thanks Chris, Just watched this.

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.

Options are 709, 2020 and P3.

I didn't get a shade in the box. I guess they thought the brightness of the screen would be able to break through the brightest sunlight. Here are some pictures of the external routing to the m24 port on my a7rv housing. They do also supply a m16 port connection that has a moulded-in flat ribbon.

So, i designed the hard mount to provide a compact, slightly tilted view for what i thought would be the majority of my photography. I also designed it to accept the standard ball mount arrangement if I need it of find that the hard mount doesn't suit me after all.

My eyesight is the frustrating thing. I've always used the rear screen and never the viewfinder. 99% of my experience has been with seafrogs where the rear screen is always flat on the camera. I've only just made the change to Nauticam that has the screen sitting slightly tilted up, which is actually a big improvement. In the end though, while I have a prescription mask that I've updated over the years, the camera screen is just too small and I'm hoping to get a new lease on life with the external monitor.

The monitor is already in a housing. It's a dedicated underwater monitor.

I've not done video... yet. See video of the screen settings under HDR... is this what you mean? 20251021_184511_640x360.mp4

This is how the hood looks, printed in ASA and vapour polished. This again is only printed in a lightweight, standard profile, so it might not be robust enough. If i print it as "strong", its quite a bit heavier and I will need to increase its volume slightly to compensate. I'll try this one first and see how it goes and how long it lasts.

This is just a prototype in PETG. It's a simple U shape with one hole sleeve for the mounting. I'm intending to print in ASA/ABS and surface smoothed to try and ensure it remains sealed. Time will tell how long it lasts.
