Great examples James. Thanks for the info.

Bokeh

Bokeh and the sharpness of the subject at given aperture seems to differ with every lens. Your lesson on the 600mm is as informative as it can get. Thank you.

Very nice examples of the effects. Wanted to add to the comments that it also depends on how far away the background is to the subject. At different background depths each f stop will give a different effect than the ones shown. Things like lighting, blade shape and configuration, lens quality also come into play. My Canon lenses gave a much different bokeh than my Leica or Schneider lenses do as will a Nikon lens. This gives a good general visual representation of how it works. A nice starting point for folks to consider.
