DXOMark measures more technical aspects of a lens, especially its resolution. It doesn’t capture everything about a lens, and some lenses that score poorly on DXOMark may have other beautiful characteristics that make them worthwhile beyond just resolution. That said, DXOMark have reviewed Sony’s 24-70 F2.8 FE and find it to be an excellent lens.
One of the features of this lens that DXOMark doesn’t capture, but is of importance to fashion photographers, is the bokeh of this lens. Normally 24-70mm lenses are not known for smooth out-of-focus areas but this lens does surprisingly good in this area. This lens is weaker at the 70mm than the 24mm end, but that’s not unusual for this type of zoom lens. This lens can replace several primes for you if you can live with the F2.8.
