SUMMARY
The Sony FE 28-70mm f/2.0 GM lens provides a constant f/2.0 aperture throughout its 28-70mm zoom range, a feature previously considered fantastical. It boasts a complex optical design with multiple aspherical and ED elements, delivering sharp images with excellent microcontrast and minimal chromatic aberration. The lens includes robust handling features like an aperture ring, zoom tension switch, and customizable buttons, alongside fast linear autofocus motors ideal for both photography and videography. While heavier and more expensive than some alternatives, it offers a full stop advantage over f/2.8 zooms and is more compact than its Canon f/2.0 equivalent.
