Seafrogs Underwater Housing for Sony A7iii A7riii +WA005F Dome port Kit [40m/130ft] Waterproof Case with 6" Dome for Sony A7r3 A7m3+ 16-35mm F4, 28-70mm F3.5-5.6

I bought this on a friend’s recommendation and was skeptical about the quality and durability. After using this for the last year and a half I’ve been very impressed. I have had zero leaks and the images through the dome have been sharp. That being said I make sure to inspect the o-rings very closely and use the silicone lube provided. I have had a few scratches but was able to get rid of them with some acrylic polish

Purchased from Seafrogs for scuba diving. Very bad alignment issues. Got this Seafrogs salted line and dome port for my old Sony a7III and Sony 16-35G PZ. The zoom gear mechanism is pretty iffy. The control dial is not aligned such that you can't change modes from aperture priority to shutter to auto etc. The worst is the on/off switch. If the camera is on, it will allow you to switch it off but won't let you turn it on again. You will have to take the camera out to turn it on again. The other buttons are fine (don't have to be precisely centered to work). Too bad I spent about $800 on the housing and dome port, plus additional on the vacuum pump. I feel that I've been had.
