Upload & Sell: On
It seems that some people, including Canon obviously, believe that 200-400L will be a smashing success if and when it starts selling.
I am not so sure, given its anticipated price of $10k +.
Gearheads like ourselves tend to get very enthusiastic about novel gears, yet, when it comes to parting with $10k+ for one lens, the enthusiasm often fades.
Let us try to understand what are the reasons for our interest in 200-400L, or, to put it slightly differently, why should a zoom of that type and postulated specs/price succeed ?
