This is my very first L lens and it's absolutely wonderful. I did find it to front focus just enough that I have to be very careful.. such as moving subjects away from the camera. That'll have to wait until I get a camera with AFMA.
By the way, anyone know how much it would cost to replace the front element? Bought mine used for a decent price. It has hair width scratches. Can't tell in images so no problem.
