Bokeh comparison 50mm f/2 AI, AFS 50mm f/1.8 G and 55mm f/3.5 micro at two different distances. The 50mm f/1.8 G seems to be a clear winner with repect to bokeh over the 50mm f/2. In its aperture range, the 55mm f/3.5 micro is second place, although part of that may be due to longer focal length. The files marked -P- are in proper portrait (head shot) distance.
