I test the camera by setting it up for “dummy mode” as by doing so I will no need to getting myself busy with controls. It is rather easy to operate with the shutter release. At first, I just not able to get the zoom ring to turn, however it not really matter since the wide angle is good enough for underwater shots anyway. It would be best and I would suggest the manufacturer to come with a zoom lens left at wide angle or a wide angle prime lens.
The DiCAPac WPS10 waterproof case notary seals at 2 points. An Ultra Violet coated polycarbonate lens anchoring screws onto the case within the digital camera lens. Towards the top, the seal case is look like a zip-lock baggie, and then fold a flap over for a couple of times as it is a dry bag. The seals also is with velcro. Lastly, a big velcro flap folds within the more compact flap. I’d point out the fact that this waterproof case is having a higher chances of leaking from a puncture rather than leak from the seals.
I bought this DiCAPac WPS10 waterproof case and bring it on a snorkeling trip recently. In spite of tested many times before use it on the trip, the case is actually getting leaking around the lens ring during my testing when I try to put it into the salt water and causing my Nikon D3100 DSLR camera getting damage due to the leak. It is better for you to invest your money on a $1500 hard case underwater housing if you really care about your camera. This DiCAPac WPS10 waterproof case just not worth for you to take the risk as it may ruin your expensive camera as well as your sentiment during your snorkeling trip.
