Yes, by all means, congrats and all that! And, speaking as a consumer of Canon products, "You're Welcome!"
But with multiple manufacturing lines running simultaneously, does it strike anyone else as "interesting" that the actual, identifiable 100 millionth lens just happened to be their current flagship zoom, the ultra-cool and ultra-expensive 200-400 "rock star"?
The press release just wouldn't have had the same pizazz had they announced that Number 100,000,000 just happened to be lowly 50/1.8, now would it?
Surely, they didn't stop all the production lines after Number 99,999,999 just to hand-assemble another 200-400, so it could claim the prize ...
