Not perfect though : see rendition of twigs in a distant background (my latest december post). In such case, the overcorrection of spherical aberration becomes apparent, leading to edgy twigs. In your shots above, there is no significant outlining.
One cannot expect a lens to be perfect at all apertures and distances, should size and weight remain decent, as is the case here. So far my only "faultless" fifty was the Zeiss Milvus 50/2. The two extra stops provided by this Voigtländer are worth giving up some of the Zeiss perfection, in some circumstances. None can replace the other. I find the Voigtländer particularly well-suited for B&W.
