In response to one reader, I have added color images to this aperture series, in addition to the previously posted black and white renditions. The color versions show the degree of magenta/green color bokeh of secondary color and of violet fringing.
This close-range series from f/2 through f/8 is to show general rendering style. In particular, the 50/2 APO has such impressive color correction that it makes a super lens for black and white photography, as shown here.
Includes image up to full camera resolution from f/2 through f/8.
