Here are my first 2 images with the new Zeiss wide-angle 'ExoLens' for iPhones, in my case the iPhone 6s-plus. This lens widens the iPhone's ~29 mm effective view to ~17.5 mm. Using the Cortex camera app gives me slightly more detail with its 27 mp image than what the iPhone can provide with its default 12 mp image. Foliage isn't too great with the iPhone in any case, but the amazing thing about the ExoLens is the relative sharpness edge to edge. The ExoLens is serious glass, weighing nearly as much as the big iPhone. For comparison, the cheaper Olloclip lens for iPhones is very distorted and blurry toward the edges. iPhone 6s-plus, Zeiss ExoLens, Cortex Camera App, daylight exposure. iPhone 6s-plus, Zeiss ExoLens, Cortex Camera App, daylight exposure.
