Best lens I ever bought in my life. No more comments!reviewed July 8th, 2016 (purchased for $1,825)
Note: the "stiff" zooming is caused by the customer's mistake: the lens is supplied with its zoom-lock-ring put into the "lock"-position. Please, unlock, turning it to the left (anti-clockwise). Otherwise it will remain stiff, until you destroy the mechanics of this lens. So be careful with it, to enjoy!
