That sounds better. Now, the question is: If you have a 9" prime lens that will look 14" long with the lens hood attached, could you get by with the lens hood reversed, and then put it on once in? And second question: If you have a 9" lens, could you get by with a 1.4x or 2x TC in a pocket, and attach that once inside? It follows the lens under 10" rule, though would be over 10" with the TC attached, and the lens hood extended.
Hmmm...all the ways one could try to flout the rules!!
In the end it's semi-ironic, as the intent which one would presume to be avoiding someone from getting unauthorized press-access through the standard crowd access, or for privacy protection of drivers, celebs, etc that the longer lenses could theoretically reach...yet it's the superzoom P&S cameras with their 800+mm equivalencies that actually can more readily zoom in from the stands to the starlet smooching with the F1 driver in the pits, or the pit crew doing something unseemly or ungentlemanly during the race...even some 10" DSLR lenses can't get as close in as some superzooms can!
