why should canon rebate their big white lenses. I think that everybody who bought one, would own it until he dies ;-)
I was looking more than one year to get a uses one, but their wasn`t any offer !!!
So in May I bought a new one - it`s an awesome lens, the best lens I ever had - - I will own it for the rest of my life ;.)
The price since may is exact the same - I don´t think canon will rebate it.
