I have always taught folks that shutter speedsof 1/4 or 1/5 sec. are best for creating zoom blurs. At Heislerville, NJ there have been groups of 10,000 to 15,000 shorebirds on the late afternoon high tides. Denise and I have enjoyed creating a variety of blurred images especially at dusk. Not sure why but I tried for the zoom blur effect while using a relatively fast shutter speed of 1/30 sec. I zoomed from 400 to 100 as fast as possible. To my surprise, I got some nice ones.

Don't be shy; all comments welcome.
ps: The bulk of the birds were Semipalmated Sandpipers.
