I couldn't agree more with everyone else.
The 24-70II is indeed one heck of an all rounded lens. And yes, i too sold away all my unused lenses to fund this one and i might end up selling more because this replaces many other primes.
I do 90% portraiture and this lens fulfills almost everything i need to shoot portraits. Yes, for nicer bokeh and sharper close ups i still use my Sigma 85 for those shots but for everything else, this lens is pure magic at every focal range at any aperture i throw at it. i've done many shoots entirely on this one lens alone. I sold my 35 and 50 because with this, i simply don't need them. I also stopped using my 17-40 or 24-105 because they don't come close in terms of sharpness.
Here's an example of why i love the sharpness of this lens..the photo is post produced but because of the quality of the lens, the details were there to be brought out…
