Sony has announced the FE 20-70mm F4 G, a standard zoom that extends out to the ultra-wide region while maintaining its reach at the long end. The unstabilized lens offers a constant F4 aperture in a relatively compact and lightweight body.
The 20mm starting point gives an additional ten degrees of diagonal angle-of-view compared to 24mm (for reference, the difference between 28 and 24 is around eight degrees). Sony points out that this means you can still maintain a wide angle of view even with the additional crop applied by engaging digital stabilization in video.
The lens weighs 488g (including the supplied hood), is 78.7mm (3.1") wide and 99mm (3.9"), extending to around 139mm (5.5") when fully zoomed-in. It has a 72mm front filter thread. As you might expect for a modern zoom that covers the ultra-wide range, it requires digital correction as part of its design.
