They recently released an STF 135/3.5 lens that includes two apodisation filters. They say, "This techinique works to minimise two-line bokeh and give images similar to those human eyes perceive". I do not know who had the original idea, but this approach seems practical for consumer's products. When a Zeiss engineer was asked if Zeiss takes bokeh into consideration, he answered, "We are concerned exclusively about highest image quality in focus." This is what I read in an interview article in a certain photojournal. How about Leica? Cheers, Mikiro Strasbourg
