Bet your well pleased.How about movment across the screen!
Im going form a Mk3 to the 7-55 and the Mk3 was good.
I have just seen Street Kings and am still amazed, in what other scenes/movies would movement across the screen be tested?
I have to say, you can notice the local dimming if you have a black screen with i.e. a smaller white logo in the lower right corner, then you kind of see that the surrounding of the logo is a little brighter black than the rest of the screen. But if you watch normal TV (SD or even better HD) or a movie, this won't be noticed.
