Got my 24-70 f2.8L II today

Put it in my signature already

Only had chance to take some test shots indoors with and without a speedlight.
Everything seems pretty cool so far

Very crisp and rich images. I actually did a quick comparison between the 70mm end with the 70mm end of my 70-200 f4L IS lens and it seems that the 24-70 f2.8L II is a bit sharper even without IS. Impressed as I thought I've read somewhere that the 70mm end is it's weakest area.
It balances well on the 5D MK III...I guess you could say it's a little heavy, though after a while of use i felt the weight helped me keep the camera nice and still. Actually, hanging round my neck with my optech super classic pro loop strap it doesn't feel a bad weight at all really.
The focus ring is really nice and smooth. The zoom ring is fairly tight but I guess that may loosen with a bit of use. One thing I noticed is that the zoom ring feels a little bit less smooth at 24-28 then it smooths out nicely and then is a little less smooth again at 50 -70. Nothing dramatic but it is noticeable. Anyone else notice this with their copy?
