Thomas, Golunvolo and Tom, thank you again for your support.
We are about at the end of this story, but there might be more to come at the end of this month (surprise). Statistically speaking: from Tuesday evening through Thursday noon (1 ½ days), I took around 850 pictures, of which more than 300 were eliminated straight on i.e. bursts of 3-4 images at 8-12 frames/s of which one is kept. So that left me with 550 pictures uploaded to Lr. Of these, 50 are considered printable, and you have seen already 30 of it. I was quite surprised about the high "retention" rate, which normally does not exceed 5%. I was also surprised about the low level of pictures taken, which would have normally been twice as high, and for which the sole explanation I have, was that I only concentrated on two cars, and one team.
For Tom: the Nikkor 16-35mm f/4 is a great lens. In another thread: "16-35 vs. 18-35"
http://nikongear.net/revival/index.php/topic,2691.45.html you can see the exceptional definition, up to the corners. To my surprise, there were very little UWA situations, at least less than I expected. But this will not be a reason to leave the 16-35mm home, next time. And I found the chosen combination (16-35, 28-300, 300mm) ideal, but one should know that I'm not owning one single lens belonging to the Holy Trinity (14-24, 24-70, 70-200mm). The only criticism I have on my choice, is the need for wider aperture in the midrange (50-200mm range), not because of the lack of light, but to keep down the DOF, as backgrounds are, in most cases, not desirable.
Anyway, I have a further look, and see if I have some more to show 😊
