well you guys already covered it but...

While it's nice to see a better-looking MTF chart we all know the theoretical doesn't necessarily translate to the real world. The original 24-70 does have some problems but they fall under the "no lens is perfect" category imo. It's a fine zoom that could've really benefited from IS. Price, size and weight would all have to increase but as it is Canon (nearly) doubled the price without adding the one feature the lens "needed" most.

And short 2.8 primes with 7-blade apertures don't do much for me, IS or no IS.
