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.

Astrophotography & Low-Light — A7S (2014): The original A7S pioneered the concept of a camera optimised entirely for low light. Its 12.2MP sensor has enormous photosites — extraordinary high-ISO performance that still holds up. Lacking IBIS and limited to 1080p internally (4K requires external recorder), it is a specialist tool. For astrophotography, event videography, or any scenario where light is genuinely scarce, it remains outstanding.
