In my opinion, is 0.7 times something little. When it comes to a major in a small space Capture angle (because that's the point in most cases), then 0.6 the ideal for me. For me is the 0.7 Effect too low, because what is the point if in a distance of about 3 meters half a person more comes to the image? However, less than 0.6 brings an excessive distortion. The build quality is great, but I would have gladly missed the conversion lens 5 stars, but one must also see the sense.
