ChrisF, that is correct it is 1/100th. It isn't a full prop rotation though. In order for the full rotation, it would require about 1/30th or slower. That shot would be a "throw away" if I wanted to submit it for some publication of aviation photography. Fortunately, I don't do anything in that industry! I should have phrased my response above to say "in order to get a full rotation, I had to go to". Thanks.
