In my opinion this lens is a deception for full format digital. As far as I remember it delivered quite good results on film with a Bessa L. It's based on the famous Topogon design and it's slow. With an Alpha 7 there is vignetting wide open which doesn't completely disppear when closed down. Edges are soft (or distorted) wide open and even closed down they are softer than the center. The lens has no close focussing facilities. However it is extremely small and lightweight, but it's quite expensive. I will try it on the A6000 later.
