Review and comparison with Voigtlander 40mm f1.2 and Loxia 50mm f2
If you want to use it for landscape and architecture photography stopped down you should best stick to f/8.0 [...] Bokeh at most distances is unobstrusive and smooth, only at full body portrait – depending on the background – the corners might look a bit messy. Flare resistance is surprisingly good, especially stopped down.[...] Size and weight are still a delight for a lens with these parameters.
