Sony FE SEL2070G 20-70mm
Its unprecedented 20-70mm zoom range starts at an ultra-wide 20mm, a first for a standard f/4 zoom, paired with a constant f/4 aperture and a lightweight 488g, weather-sealed build. The lens delivers outstanding G-series resolution across the frame and refined video performance with minimized focus breathing, while its 0.39x maximum magnification offers excellent close-up capability throughout the zoom range. This is the ideal single-lens solution for travel photographers and hybrid shooters who need wide landscapes and standard framing without swapping optics.
