Ewa Marine D-MM

SUMMARY: These types of bags are awkward to use, and do not work well with all types of cameras.

I bought this for my Nikon Coolpix 7900. According to Ewa Marine this is the model best suited for my camera. I was going on a Caribbean Cruise and planned to do some snorkeling or cave tubing, or something involving water. In the past we have bought disposable underwater 35mm film cameras. But I had this nice digital camera, and I wanted to be able to take digital photos in a wet environment. When we were in Grand Cayman two years ago, the excursion photographer had an Ewa-Marine bag for her digital SLR and flash unit. It seemed to work great. I researched and found the model that was supposed to work for my camera was D-MM and I could buy it for under $100. On the other hand, Nikon makes a shell specifically for my 7900 camera, but it cost over $200. I decided to go with the Ewa Marine. First, I found the directions kind of confusing. Then when I placed my camera inside the bag, it was kind of loose. I was also worried about the lens on my camera which extends when turned on. Would it hit the glass? What would happen if it hit resistance?
Anyway, on the cruise, we booked a cave tubing excursion. The camera was awkward to manipulate when inside the bag. It worked in daylight. When we entered the mouth of the cave, and the camera needed the flash, the flash would reflect off of the inside of the bag’s glass, and the camera would take a picture of a white blur. Without the flash, the camera could not a take a decent picture in the available light…at least with the settings I was using, and it would be difficult to set up in this awkward bag floating on a river.
As we left the cave and I had light again, I was able to take pictures again. The pictures all seem fuzzy maybe due to water drops on the glass? At one point I went to take a picture, and my camera showed a lens error. This happens when it tries to extend the lens and hits an obstruction. Apparently it hit the inside of the glass. I had gotten this before and can usually cycle the power off and on to fix it. But this time with the lens halfway out, I couldn’t get it to do anything. I stopped on the side of the river and took the camera out of the bag, and couldn’t get it to reset. I sealed the camera back in the bag to mess with it at the end of the river. Later, on the bus back to our ship, I did successfully get my camera to reset by slapping it softly but firmly on my hand while cycling the power.
I found the bag very disappointing. They may be great for a different type of camera. I don’t think they will work well with any camera that has a lens that extends. I don’t think they will work well for a camera that has a built in flash.
I will probably sell this bag on eBay, and maybe buy the Nikon underwater shell.
