We have probably the best article in this topic:

And probably for the same reasons I explain here. The electronic IBIS must know the real lens FOV to electronically compensate your movements.

Since we are really splitting hairs now 😄 Here is my take. One aspect nobody has talked about is shooting in murky water with the WWL. In my experience, the WWL suffers from the same issues as the EMWL, and I don't see why it would be any different. I happened to shoot video in a river where there was a lot of mucilage in one area. The mucilage particles inevitably ended up in the space between the lens and the port. Unfortunately, you couldn't see anything with the naked eye on the monitor, and by the time I moved into an area with crystal-clear water, it was already too late. My buddy, using a standard port, brought home several good shots. Mine were all to be thrown away. Also, for anyone who takes video seriously, I should point out that wet lenses that change the lens FOV trick the IBIS algorithm, which needs to know the focal length of the lens. The impact is minimal, but the footage will never be rock-steady. People have always thought I was a bit crazy, and I believed this was a problem with Panasonic, which has the best IBIS on the market. Then recently, @bghazzal sent me a link to a Nauticam page about Sony cameras that talks about this exact issue: Nauticam "forgets" to mention that 99% of the time its users are using zooms and not prime lens...

Hi Rafa, Welcome aboard! I'm hearing "downsize" a lot, lately... Ciao

From what I understand, then, the button on the Nauticam housing works. I don't have a Canon, but... check the EVF settings. In Lumix cameras, there are settings where the EVF and the display can be set to activate exclusively. As soon as you bring your eye close to the EVF, the display turns off. There is a proximity sensor near the EVF. When you close the back of the housing, it's as if you were bringing your eye close to it. Maybe there is some setting causing this mess. Without the housing, try covering the EVF with a finger and using the button to see if it works. Ciao

I have it too on my Nauticam port but it didn't show on video.

Hi Alex, Welcome aboard! We hope tou enjoy the forum. This is an introduction forum so it's better post questions on the relevant forum. Ciao

As I already wrote, the WWL front element has no coating.

Not the documentary you want to see before a blackwater dive 😀

Hi Mike, Please add a Jpeg file.

Let us know how it went. I'm curious to get some feedback on Mediterranean BWs Ciao

Time for a little coming out: I scratched my WWL twice, and both times it was diagnosed as fatal (keep that in mind for when I put it up for sale 😉). Huge shoutout to a very talented friend who completely rescued it, minus a tiny little speck that I can only see if I shoot straight into the sun. It was just too deep to get rid of completely. Anyway, Nauticam confirmed that the coating is entirely on the inside. So, breathe easy. P.S. I'd give Novus a shot before escalating to cerium oxide.

The L10 has a different sensor (many say it's the GH7 sensor) without extra crop: f = 10.9 - 34mm (24 - 75mm in 35mm equivalent in 4:3, 3:2, 16:9) (28 - 88mm in 35mm equivalent in 1:1) https://www.panasonic.com/uk/consumer/cameras-camcorders/lumix-digital-cameras/premium-compact-cameras/dc-l10.specs.html
