For an all-around high performance lens for the A7 IV, I recommend the new Sony FE 24-70mm f/2.8 GM II. This ultra-sharp zoom covers wide angle to short telephoto focal lengths perfect for landscapes, portraits, street photography and more. The fast f/2.8 constant aperture maintains excellent image quality and separation through the entire range. Optical stabilization also helps when shooting handheld. For those needing an even more versatile range, look at the Sony FE 24-105mm f/4 G OSS as an alternative.
