Hi everyone. I'm also interested in this topic. I currently dive with Sony A7CR, 28-60 and WWL-1. I'm interested in a dome and fisheye only for splits. For budget reasons I'm looking at the Sigma 15mm fisheye on an adaptor. Both can be had 2nd hand for good value. So, I'm wondering about the 230mm glass vs 8.5" acrylic. I'm sure the 230mm is superior image quality but given the weight and cost difference I'm thinking the 8.5" might be 'good enough' just for some splits.

Happy to share some pics.

Sure. There are a few big differences between the A7CR and the A7RV that you'd have to be comfortable with. That's the price you pay for having something much smaller, lighter and cheaper. One is the EVF and screen. The A7CR doesn't have the amazing 9mp EVF of the A7RV but just a 2.3mp EVF which is also smaller. The screen is 1mp rather than 2mp. I find this just fine as I mainly use the screen. However, for people who normally use the EVf they'd probably notice a big difference. The other big difference is the EFC shutter which limits the flash sync speed to 1/160th.

Tino. I'm using the 28-60mm Sony lens with the Nauticam wet lenses: WWL1 and CMC1 & CMC2. All these work brilliantly with the 28-60.

Hi everyone. I recently bought the A7CR and have just come back from diving with it in the Caribbean. I upgraded from M43 so don't have a comparison with the other Sony FF options. However, my experience was fantastic. My understanding is that this has exactly the same sensor, process and AF as the A7RV. It clearly has the lower 1/160th sync speed given it has the EFC shutter. I found the AF to be excellent and the animal eye detect astonishing. I have the Nauticam housing which is amazingly small light and compact. It's smaller than my previous EM5Mk3 housing. Taking the camera and housing together there's a significant cost saving over A7RV. Happy to share more of my experiences.

Hi. I've been diving and shooting photos for over 10 years with various M43 cameras (latest is EM5 Mk 3). I'm thinking about stepping up to the new Sony A7CR which seems like a smaller, lighter A7RV with only a few limitations. I'd love to hear from anyone who has dived with the A7CR. I'm especially hoping it will have the same outstanding manual white balance at depth as the latest Sony A7 cameras.
