Milk thistle flower

Another rescued lens. This one is a 50mm Schneider Kreutznach Radionar f2.9. These can only be used for close-up work because at 50mm you can't get the glass sufficiently close to the sensor/ film plane for anything more distant. Focusing is by the sway backwards and forwards method. It is quite sharp wide open and gives a super bokeh. View it large to see how good it is.
