Leica S2 review updated
I’ve added a new Malfunctions page to my review of the Leica S2 in DAP.
I’ve also added an evaluation of violet fringing (purple fringing) to the Axial Color page, for the Leica 180mm f/3.5 APO-Elmar-S. No, violet fringing is not banished with APO.
One of the very few lenses capable of neutral color is the Coastal 60mm f/4 UV-VIS-IR APO macro. Or the Voigtlander 180mm f/4 APO macro. That’s all I know, and I have five Leica R APO lenses.
By the way, if you are white balancing using a gray target with virtually any lens (eg something other than the Coastal 60/4), always be sure to focus on the target precisely where you intend to set the white balance, otherwise you will get a magenta or green cast from color bokeh.
