My guess is Canon realized this milestone on account of Peter's unexpected, last-minute 200-400 order.
I will be glad to receive 90,000,001.
As for the photo, it's a composite. Each lens was photographed separately. Actually, it's quite possibly a CGI image. In any case, the lenses behind others have the same clean highlight, which hasn't been obscured by the lens in front. Also, if you look at the reflection of the front row of lenses, you'll see white spaces between them, whereas that doesn't exist above the reflection. I don't think these kinds of images are done in 'one shot' any longer...
On a tangent, but this might be fairly representative of the current state of product 'photography.' A friend who works with ad photographers has indicated many he works with are routinely hired to shoot the scenes in which product will be placed (such as a car), with the product itself being CGI.
