Just bought the LenzO for my iphone 7, which I know is a bit dated already, but I did not feel like taking another camera on my trip to the Galapagos. The trip was free dive/snorkel only, which brings a set of challenges to any camera use. I can stay down quite a while, but you have to be fast on shots. Not much time to carefully frame, focus and then shoot on free dive in the shallows. I contrasted the use of the LenzO with a companions gopro use. I would like to stress that none of us are high end photographers, although I dive with them often. That said, here are my thoughts. The buttons to take the photos threw me off a bit. The best one for a fast shot was the one on the bottom of the case. Took me a bit to get used to that. And you had to hold the case with both hands to get a shot. At times it would have been nice to hold on with only one hand and shoot. I got through this by just putting it on video instead for these instances. Switching from photo to video was easy though, as was zooming in, really appreciated that. Image wise, the gopro video was a bit better, but - again, this is the iphone 7. My friend that has an X would get much better results I am sure. Still overall the images were good, the housing never leaked and never fogged up (unlike more than one gopro I have used over the years, and I put my gopros in a housing even the new ones. Salt water is hard on them - I use them at work). In fact, I was rather cavalier with shoving the phone in and out of the housing. I was amazed that I did not have issues. So - great housing. Use of the phone instead of a camera with a more sophisticated sensor will always be a limitation, but worked for me on a two week trip. Note that if you are taking a shot above water after being under, carefully bring the dome up out of the water very slow and smooth a couple of times until the water clears off entirely with no drops. Got some nice shots. Will take it diving next.
