Sony G SEL2070G 20-70mm
The 20mm ultra-wide end on this constant f/4 standard zoom sets it apart, delivering an expansive field of view unmatched by typical 24-70mm lenses. Its 0.39x maximum magnification and 9.8-inch minimum focus distance (manual) enable versatile close-up work, while dual XD Linear Motors provide fast, silent autofocus ideal for video with minimal focus breathing. This lens is best for landscape photographers and hybrid shooters who need a lightweight, weather-sealed zoom for both stills and movie capture.
