I've been meaning to do a more detailed analysis of the Moment lens kit but haven't had the time to. I took the wide lens out camping with my brother and friends last weekend. But due to too much fun I gave up photographing anything. The weather was just too nice and hot to sit around and get into the science of comparing iphone w/ lens vs non lens output. I promise ill get around to it soon.
For now here are a few shots my buddy Sean & I manage to take using the wide lens. Notice the vignetting around the corners. Ive made the image black and white so you can see it easier, its subtle but still there. In full color it's less distracting.
