its exactly described here, what I wanted to use, I believe more and more that my camera has a problem...

thanks for that descriptions, the only thing is that I 'm not using object tracking, its off! I used only cont autofocus, tried it with a stativ and a not moving subject which is easy to focus (good contrast and light). And yet the frame does not match the focus point. Roughly it looks like the picture I have attached. (Sorry for the primitive drawing, but I gave my A7R5 back to my dealer yesterday, looking for a new system now). It's not always the same result, but I got deviations with every new focussing even though camera and subject are fixed. Underwater it made live really hard.

It's not only underwater, its also when I work with a stativ on land (A7R5). I set the Focus point on a not moving object with cont autofocus, and get a larger frame around but not exactly where my focus point is, even when it is something like a intersection of a cross, which is easy to focus. I'm sure this was not the case when I started with the camera in 2023. The example is a 0,5 cm fruitfly, with the focus (hand hold) direct on the eye. I dont know if its depending on the focus point, but the continious autofocus is not aligned with my focus point.

My friend has a Canon R5 and he can choose a significant smaller autofocuspoint. I put an example (land) from my A7R5 here: this is cropped by around 200 %. Its not really sharp, the conditions were perfect, its 1/250 F16. Object is 1 cm. Problem is, I can focus the front of the insect, but not the eye. Underwater its the same. The second picture is with Nauticam SMC3, cropped 300 % for demo, focus on the front of the nudi is hardly possible but not on the "horn, (rinophore?)" as you can see. So as a result I'm not sure if I should change the setup. Supermacro is my really passion.

Hi, thanks for your comment, I have actual the A7r5 with the sony 90mm setup in an Isotta housing. But since one of the firmware updates the Small Focus point is not really working for me, almost never hit the exact point. I use cont autofocus with tracking, but tried also Manual. Last trip to Anilao I had somehow 70 % not in focus, comparing with other trips a really bad result. For Supermacro the focus point seems to "big" for me. I tried it also on land with the same result.

so, let us assume 25000 Euro. Including also something like viewfinder, monitor etc... Wishlist is Macro, Supermacro still and video. Questions I ask myself, like the best macro lense, same setup for still and video, for example viewfinder or monitor, Sony: really the 90 mm which is so hard to focus ...

Ah ok, good point, mainly shooting in warm water, Macro, Supermacro (video) on the wishlist.

Hi all, what macro setup (which macro lense-camera combination) would you buy when you could start from begin? Should have also video capabilities. LG Susanne

Price for the pure housing is 2000 Euro. Including the manual trigger and a spare trigger from Isotta. What could be sold together, is Macro port, Vakuum check, Backscatter trigger, camera, 90 mm macro from Sony ... More Pictures can be sended. Housing is in perfect condition. Shipping in Europe, located in Vienna for personel visit.

SOLD!

I had the same issue before 2 weeks, let it closed overnight, and next day when I opened it, there was a little water inside. Luckily it worked after drying. I did not found any problem on o-ring or elsewhere. I changed the almost new o-ring without really thinking that this was the issue :-(.

Thanks again, I ordered exactly a 24-16 adapter, and another adapter for M16 (picture) to be on the save side, if it arrives tomorrow , my problem should be solved and I could use the BS trigger in Anilao 🙂

Hi meanwhile everything works! The problem was the camera! After resetting it and configure step by step, testing with a Godox flash, it works. Now unfortunately I have the problem that my Backscatter Dual Bulk Head adapter doesn't fit on my Isotta housing, I think the cutout for the hole part diameter is too small, so I cant be completely screwed in. It leaks :-(.

Thanks! Yes, I tried with wireless on/off, and a normal Godox flash works, so I think camera is working. Now I will get a pair new cables from my dealer. This is the next test. I have the single universal configuration in an Isotta house, and the thing is, it worked before! Unfortunately I do not have the double version.

Hi all, 7 days ahead to my trip to Anilao, I tested my new BS trigger with my Sony A7R5 (connected and disconnected with backscatter HF flash) again (I did it before 4 weeks, and it works all fine), but now it doesn't. The diode is not showing any light. It doesn't work with remoteflash setting on or off. The trigger akku is full, the green light blinking 5 times and then the bluelight is blinkling, Sony setup is on fillflash, M, and like writen, remoteflash on and off Am I doing something wrong? Does anybody here have the same problem. I think I got some of the first BS was selling. Many thanks, I'm a little desperate since this is so short before my trip to the Phillies. 😞
