Aaah, lol, all these R's and 5's from different brands. Didnt even realise it was Canon you were selling and Sony you are buying. But if you really want to go smaller, look into something that works behind a small 4" dome, those 230mm and 180mm domes are big, no matter what camera you have (just assuming you are going with similar lenses from before).

2 minute job. UWT trigger and A7IV.

I just listed the A7RV housings in the table since the op was looking for that. TBH, i dont see the point going from Marelux->Isotta, specially when the op has full set with all bells and whistles for Marelux. The miniscule size difference just dont justify it for me atleast. Maybe when changing camera model/brand, but sticking with A7RV makes no sense (to me).

How much smaller is the dealbreaker for you? Below are the A7RV housing sizes with base housing only. Ports ect should be fairly same size for all. Isotta Nauticam Marelux Sea&Sea Width 28.2cm 34cm 33.46cm 33cm Height 18.6cm 17cm 18.98cm 16.9cm Depth 12.7cm 12.7cm 13.23cm 13.7cm Total 59.5cm 63.7cm 65.67cm 63.6cm % larger 0 7.06% 10.37% 6.89% Weight Not listed 2.7kg 3kg 2.9kg Isotta is clearly smallest in width, and you can see that in pictures also. It also looks most crammed with buttons in the back. Wouldn't say Isotta is very compact compared to other aluminum housings, with 7% difference.

Review of somesorts from Bluewater. I havent watched it yet.

This is internal?

Atleast you can make the trip with borrowed strobes. So Backscatter strobes are just rebranded AOI ones?

Some next level DIY stuff right there. 👍 And great documentation for us to see. And you arent the only one (or the last) to notice the horrid battery life on mirrorless compared to DSLR's.

At Lembeh pretty much all are (macro)photography oriented. I have stayed numerous times at NAD Lembeh and can recommend.

Camera bodies are almost identical with small 1mm difference in size. Nauticam housing for A7V has playback lever moved from top left to a button bottom right. Also slight streamlining can be seen in the body also. I went from A7RV to A1ii and the new one has little bit different main o-ring seating than old housing, i suspect this new system is also in the A7V housing.

Unfortunately you most likely have a leak somewhere. Could be any of the buttons ect with an o-ring. You could try to use leak detection smoke to pinpoint where it is, but if its really small, it might be useless. Your local dealer can service and change everything im sure.

$1100 for the housing plus $165 for the periscope stick (Ø37x350 Carbon Fibre Aluminium Float Stick (Buoyancy 190g)) Well cheaper abroad obviously.

Looks like Nauticam is back on the compact camera housing market. Saw this pop on my socials feed, nothing on Nauticam website tho.

I thought there was a thread about Mikomoto already, but couldnt find one. Anyway. Going to Japan early autumn and have set my sights on Mikomoto. Recommendation needed on operator, accommodation, ect. The whole lot. I know theres the occasional storm when diving is cancelled and im thinking for a week, but is that too much? Also do the operator offer for example macro diving at Izu if Mikomoto is stormed off? Or is this to be arranged on your own? Lens choices, most footage is from far away in the blue, so strobes can be left in hotel im sure? Sony full frame shooter, what are best options? Or just GoPro? Any help appreciated.

Doesnt sound familiar at all, right?
