EOS R100vs X-A7vs Nikon D7500
Which should you buy?
First Camera / Beginner Photography — EOS R100 (2023): The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
Beginner Fujifilm — X-A7 (2019): The most affordable X-mount entry — Fujifilm colour and film simulations with a large flip screen for beginners.
Sports, Travel & Dslr Shooters — Nikon D7500 (2017): The D500's BSI sensor in a compact, weather-sealed body — excellent high-ISO performance and DSLR reliability at a great price.
