Should I buy the Canon EOS M50 Mark II or a used Sony A6100?

For most people, the used Sony a6100 is the better buy. It generally offers stronger autofocus, better battery life, and a broader lens ecosystem through Sony’s E-mount, which makes it a better long-term system for many buyers.

Choose the Canon EOS M50 Mark II if you can get it much cheaper, prefer Canon’s simpler handling, or especially if you want the fully articulating screen for vlogging, selfies, or easy front-facing shooting.

If 4K video matters to you, the Sony a6100 is usually the safer pick. The M50 Mark II’s 4K mode is more limited, so it’s not the best choice if 4K is a priority.

One important caveat: exact prices, availability, and lens options can change over time, especially for used gear and discontinued systems, so it’s worth checking current listings and the official source before buying.
