Amazing picture. So I did a little math and concluded a 500 mph jet traveled 1.09" in 1/8000th second. Then I thought about converting that to pixels. I saw about 3 pixels of blur against the sky which wasn't moving, and 6 pixels of blur against the other jet. Then I decided I the math was beyond me, but someone out there should know how long it would take the jet to travel 3 pixels.

I find it impressive that today's cameras can achieve such high shutter speeds, but I wonder how accurate are these speeds. When cameras are represented to achieve speeds of 1/8000th of a second just how close do they get? Is it perhaps "close, but not quite" or are they 100% on spec? Are you aware of lab tests that verify the manufacturer's claims?

To me the exact number is not as important as picking the correct speed.

I am the OP that posted the question and my inquiry never stated that "I was concerned with inaccuracies in measuring fractions of a second" In fact, I was interested in finding out to what degree the representations of speed were accurate and nothing more. Perhaps some of you were not in a position to answer the question as you were either unable to correctly read my inquiry or you added your own facts to my question. For those of you that took the time to read and correctly understand my inquiry, I thank you for your educated responses.
