Roger has stripped down the 100-400 II and reckons it could be the best engineered lens ever. Perhaps one reason why it is twice as expensive as the Tamron 150-600mm or the Sigma C.

Oh, that's neat!
Nothing haphazard about the construction of that lens.

As an engineer I appreciate well built products. I don't imagine Canon could buy better advertising. I was leaning this direction before, but this helped seal the deal.

Thanks so much for this article Roger.
It's amazing to see what goes into a lens.
Such a complex piece of engineering for relatively small money.

I recently got a new pair of spectacles which cost around $1100, which my wife thought was OK.
After showing her these photos, she won't be complaining about the value for money my L lenses are!
