Good alternatives to the Canon G7X Mark III include the Sony RX100 series (for superior autofocus and video features), the Sony ZV-1/ZV-1F (ideal for vlogging with features like a flip-out screen), other Canon G-series models like the G5X Mark II (longer zoom, EVF) or the newer G7X line-superseding Canon Powershot V1, and the Panasonic Lumix ZS200 (excellent travel zoom). For budget or interchangeable lens options, consider the Fujifilm X-T30, Olympus E-M10 IV, or a used Nikon Z50/Z30.
