GearScore™ Verdict — Which should you buy?
Travel & Vlogging — PowerShot G7X Mark II (2016): The G7X Mark II is one of the most popular compact cameras ever made — and for good reason. A fast f/1.8-2.8 lens, 20MP 1-inch sensor, flip-up selfie screen, and Micro USB charging combine in one of the most vlog-friendly compact cameras available. No 4K and no EVF are the main compromises, but the G7X II remains outstanding value on the used market.
Low-Light Video, Documentary & Available-Light Filmmaking — A7S II (2015): A landmark in mirrorless history — the first Sony with IBIS and internal 4K, its low-light video capability still impresses today at a used-market price.
