Just a few days ago I revisited the 50 Zeiss Planar, which I adored but even that lens will render a more perfect scene then the Zeiss Sonnar. I argued that it may be wise to own BOTH the Planar and the Sonnar. This way, you get your sharper more perfect look as well as your classic bokeh filled look for just about $2000, or $300 less than a Leica Summicron lens alone :) It’s a win/win.
