[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Zeiss makes a huge range of aspherical lenses for uses other than camera lenses. I see this kind of thing all the time from our Zeiss Stereo Discovery V12: http://www.zeiss.de/C1256D18002CC306/0/A1D786765758C134C1256F2F0034D395/$file/46-0008_e.pdf I respectfully disagree on the bokeh of the Leica aspherical lenses, particularly from the 35/1.4. I have a pile of the asph lenses, but I sometimes am careful about how I use them or reject photos because of the out of focus rendition.
