The lenses are well built, but the optics are disappointing. The telephoto exhibits quite a bit of distortion and softness at the edges, while the fish-eye lens picks up the outer edge of its housing, resulting in a thin red circle around the image. I stuck with the 0-degree lens most of the time.
And what about that durability? I'm happy to report that my iPhone 5s remains intact after being splashed, exposed to sand, immersed in swimming pools and the saltwater ocean, and, yes, dropped by my deliberate butterfingers.
The PhotoProX, alas, did not survive two real-world contacts with the sidewalk: on the second drop, from about 3 feet, the plastic fractured where the case met the top latch. I can't discount the possibility that it hit at just the right angle to break the housing; I did not deliberately attempt to subject it to anything other than a casual fumbling. Optrix advertises the case will protect the phone from a 30-foot drop; I can verify that the iPhone is indeed fine, even if the case was sacrificed.
Do you plan to get wet? Or dirty? Or sandy? The Optrix PhotoProX offers the protection you want when making photos with your iPhone 5 or iPhone 5s in those less-than-pristine situations. Unfortunately it did not survive a drop test (but did protect the phone). I also wish the lenses performed better, since they seem to be the main draw aside from the waterproof protection.
