Sony designed the G Master lenses with its full-frame mirrorless cameras in mind, and if you’re going to want any glass for an A7III or A9, the Sony 16-35mm FE 16-35mm f/2.8 GM is a great place to start. Sure, it’s $2,200, but this wide-angle lens is perfect for photographers who want to take wide, closeup shots. The f/2.8 aperture will ensure you get great bokeh effect, aka a perfectly blurred background, and you also won’t have to worry about the edges around your shots not being perfectly rendered.
