When it comes to accessory lenses for the iPhone, most people think of the wide variety of lenses made by Olloclip. There are a number of other manufacturers who are jumping into the iPhone lens world, making everything from cheap $10 clip-ons to the $229 iLens Pro lens kit from Schneider Optics I'm reviewing today.
The iPro Lens System consists of a macro lens, a super wide angle lens, and a 2X telephoto. Keeping the lenses safe during travel is a three-segment case that also serves as a handy grip tripod for taking photos or video. Your iPhone 5/5s slides into a case with a tiny bayonet mount onto which the lenses are placed.
As you can see from the photos in the gallery, the super wide angle lens really does give you a lot more coverage. As with most lenses of this type, however, you will see a lot of barrel distortion around the edges of the image. My suggestion for taking wide-angle photos? Just use the built-in pano function of your basic iPhone camera, or even better, use an app like Sphere to capture a 360 degree spherical image of your location.
