Ewa-Marine EM U-A100 Reviews

Decent inexpensive housing but with issues

By kevin

First of all, the package appeared to be missing parts. The instructions describe brackets and the inclusion of rings to fit the end of the lens into the housing. These were not included - there was just one lens ring. So you have to buy your own step up/down rings for your lenses. Good: The wrist attachment works great and its very buoyant. Even with a A7RII and large metal lens, no way this sinks if for some reason it comes off your wrist. The glass cover is crystal clear so it did not add anything to the image. The 'snap-in' attachment holds the lens at the end of the housing well. Not so good: The added layer of plastic interfered with the camera's finder/monitor so the monitor would not stay on. Couldn't change the setting while mid dive as using menu and fn keys and dial was next to impossible. So had to preset exposure settings and hope for the best. I could reliably adjust on/off and aperture/shutter wheels, but not much else - no way to get to the aperture ring on the lens. Bad: It leaked a small amount. It seemed air tight when testing it in the sink/bathtub as suggested by the guide. I was snorkeling with this and the first outting I didnt do any dives with it. Seemed fine. On 2nd outting, I dove down with it to around 15-20 feet. Thats when the pressure forced a small amount of water - a few drops that on the A7RII amounted to rain on a sealed body. So no biggie. However, the issues began when it seemed like the camera was overheating or the sealed nature of the bag pressed to the camera made it so there was no place for the heat to dissipate. This was in 75 degree water in Hawaii... This in turn caused the housing over the lens to start fogging up. There was no way to fix this without taking the camera out, ensuring the interior was completely dry and then adding defogger to the glass like it was goggles. Because its already pretty humid, it was impossible to get it completely clear so I really only got good images on the first snorkel.

Does the job !

I took it snorkeling with the Sony FX3 just for fun. I didn't have a prime with me so I used the GM16-35. I had to shoot between 20-35mm because the housing just wasn't long enough to support the lens at 16mm with the FX3. I went back out with the A7rIII and it worked fine at 16mm. Cool thing was I was able to mount a small Aputure LED on the top, I used the lens ring that came with it to seal it to the front glass on the housing and there was no glare. Too bad I figured that one out at the end of the day. I'll trust this on a job now. Easy to set up and the little finger indent allowed me to access all my controls. Touch screen did not work. but I don't rule out operator error on that. Also on the FX3 shooting internal 4k, that sucker did get warm but did not over heat after an hour of shooting.

For the Nikon D850 without the battery grip. Which will be a better fit, the EWA-Marine U-A100 or U-B100? For underwater wildlife / Snorkeling use.
Asked by: Lewis
The Ewa-Marine U-A100 is too small for the Nikon D850. The Ewa-Marine U-B 100 is prefect as long as the camera body and lens is not longer than 7.28". The filter thread on the lens has to be 82mm or smaller.

Would anyone recommend use for Nikon D3300?
Asked by: Deantanika
The Nikon D3300 will fit in the Ewa-Marine U-A100 Underwater Housing for DSLRs and Mirrorless Cameras. Make sure the lens on the camera has a 82mm or smaller filter thread. The lens and camera cannot be longer than 6.7". The housing includes the CA82 Adapter and the RA77-82 Step-Up Ring. If your lens has a different size filter thread you will need a different step-up ring. For more help please email [email protected]
