Tried Canon 200-400f/4L IS today & asked the price, told it didn't exist :-)

As a cps member at that show I was allowed to play with it to my hearts content. It's a thing of beauty but they wouldn't say a price

Having worked in several marketing departments, the price is the last thing decided.  Cost of Goods (production), expected demand, competition, currency exchange rates, ...  all go into the final decision

Those photos do a great job of showing the lens' size.  It's bigger than I expected.

It is hand holdable easily it seems... although more interested in samples on how it would compare to a 400 mm f/2.8 prime... and the price I believe will surpass the price of the supertelephoto primes themselves.

Sure hope that Canon keeps the price in check, especially since the Yen has weakened.  Above $12,000 hard to justify

I held it - I wouldn't want to handhold it for more than a few minutes - especially not when coupled to a ! series body
