That makes a lot of sense to me. In all the analysis, my primary thought beyond where it is used, is what could you live without? The missing 35 mm at the long end of the 24-70 is easy to compensate for by cropping. Sure, lost of pixels, and noise becomes more apparent if at high ISO, but it can be done with minimal penalty. Plus, I often have another lens in the bag that could be used to compensate.

But f/2.8 vs f/4. If you need that stop of light, if you want that bokeh, there is not an easy replacement.
