Here is an image from a shoot I did last week of 4 Friesian colts that are for sale. This was in shutter priority and the head pretty much filled the frame. So when I do it "right", even in shutter priority the bokeh is fine. The head of the Lusitano as well as the ones of him backlit on the hill are heavily cropped which makes a big difference in how much bokeh you get. I am just going to have to practice some more on using aperture when not at a real shoot, and get the "shooting in aperture" problem figured out.
